Signotaur v2.0.0.19825 giu 2026
Funzionalità
  • Safer backup restore. 'archive restore' now warns before overwriting the server configuration, database and certificates, and requires confirmation. Unattended restores must pass '--yes'. It also reports clearer errors for corrupt or truncated backups, databases still in use, access-denied paths and master key sealing failures.
  • Improved command-line output. 'archive' server command now displays clean, readable output instead of raw log lines. It also supports '--theme' ('General', 'Dark', 'Light' or 'None') and '--no-color'. Use '--theme Light' or the 'NO_COLOR' environment variable for white-background terminals.
Correzioni
  • Encrypted backup restore. Passphrase-protected '.sigbak' archives created by the previous release omitted required cryptographic parameters and cannot be restored or verified. After upgrading, create a new backup, verify it with 'archive verify', and discard any backups from the previous release. Live server data and secrets were not affected.
Signotaur v2.0.0.190Versione principale24 giu 2026
Funzionalità
  • New Enterprise Features:
    • Enterprise licenses are now available for Signotaur. Purchasing an Enterprise license grants access to new features related to internally and externally managed certificates. Note that every server gets a one-time 90-day grace to set it up and evaluate it without an Enterprise license: you get a single managed web (TLS) certificate, valid for up to 90 days, after which the server reverts to self-signed. Add an Enterprise license to keep that web certificate auto-renewing and to issue and sign with managed code-signing certificates.
    • Internal Certificate Authority: Signotaur can now run its own built-in CA hierarchy (root + intermediate) to issue and manage code-signing and web (TLS) certificates directly. This includes on-demand issuance, automatic renewal and expiry notifications. A managed certificates list tracks current and superseded certificates.
    • External ADCS issuance. Managed certificates can also be issued from a Microsoft Active Directory Certificate Services server, over either the DCOM or Certificate Services (CertSrv) web transport, using enterprise certificate templates.
  • New Features:
    • Web (TLS) certificate management. A dedicated admin area for the certificate presented by the server web interface, allowing selection of the source (self-signed, an existing PFX file, the Windows certificate store, or the managed CA), view the live certificate, its chain and expiry, and download the chain anchor (PEM or DER) with instructions for distributing it to client trust stores. Note that using the managed CA as the web-certificate source requires an Enterprise license, but a one-time certificate can be issued with a capped 90-day validity.
    • Encrypted, portable backups. A new archive command (create, restore, verify, extract) produces passphrase-protected .sigbak backup bundles containing the configuration, database, and CA/managed certificates. Restoring a bundle on another machine re-seals secrets under that machine's key, providing a supported migration path. Scheduled backups now emit a full .sigbak archive when a backup passphrase is configured.
    • At-rest secret protection (DPAPI). On Windows, the master encryption key is sealed with a machine-bound DPAPI key, so an off-box copy of the configuration, CA private keys, and other at-rest secrets (VM snapshot, copied disk) cannot be decrypted without a proper restore. OAuth client secrets are now also encrypted at rest.
    • Per-API-key rate limiting. Optional fixed-window rate limiting can be enabled for gRPC signing endpoints, with configurable request counts and window durations per API key (off by default).
  • Improvements:
    • Most server settings now take effect immediately, without a service restart -including email, event retention, password policy, session/login expiry, update-check preferences, the PKCS#11 PIN-failure limit, and enabling/disabling rate limiting. Settings that still require a restart (hostname and port, OAuth providers, log-file changes, and changes to an active rate limiter) now clearly indicate so with a restart-pending banner.
    • Configurable login session lifetimes. A login where "Remember me" is left unticked can now be given a shorter idle timeout, separate from the longer remembered-login lifetime, so unattended sessions expire sooner. Administrators can also choose whether sign-ins via external providers (Google, GitHub) stay signed in or last only for the browser session. Both are set under Settings > Options.
    • Concurrent-edit protection across all configuration screens: saving uses optimistic-concurrency tokens, and a conflict dialog shows when another administrator changed the same settings (and who/when) rather than silently overwriting them.
    • Editing settings now warns about unsaved changes before you navigate away, and a pre-save summary lists exactly what will change and when each change takes effect.
    • The installer offers five certificate-configuration modes (existing PFX, Windows certificate store, self-signed, built-in CA, and external AD CS) with dedicated sub-pages, and validates your selections - PFX/store certificates, self-signed generation, AD CS connectivity, and subject names - before letting you continue. The installer also honors the configured backup directory and takes a pre-upgrade backup.
    • The admin web app gained consistent save dialogs, buttons, dirty-change detection, and certificate-table layouts throughout.
  • Infrastructure:
    • Updated .NET SDK to v10.0.301.
    • Various third-party package updates.
Correzioni
  • Reworked several account and configuration forms to react correctly to edits - fixing cases where a submit button could remain disabled.
Signotaur v1.2.0.16111 giu 2026
Funzionalità
  • Detached CMS signing is now supported for archive and disk-image formats (.zip, .7z, .tar, .gz, .tgz, .bz2, .xz, .iso, .img, .vhd, .vhdx) via the new --detached and --signature-file <Pattern> options.
  • CMS and RDP signing now support ECDSA code-signing certificates in addition to RSA.
  • Unsupported file types that are detected to be valid PE images are now automatically signed with Authenticode, including staged .tmp binaries produced by build tools such as InstallShield.
  • The server now translates low-level cryptographic provider errors (CSP/CNG/KSP) into clear, actionable messages when signing or loading certificates, instead of surfacing raw error codes.
  • PKCS#11 signing now verifies each signature before returning it and automatically retries transient token errors, improving reliability with hardware tokens and HSMs.
  • The message shown when an unsupported certificate type is used for signing is now clearer.
  • The client now returns more specific exit codes for a wider range of failures - including Win32 file errors, additional CMS/cryptographic errors, and AppX/MSIX packaging errors - and previously unmapped errors now map to dedicated codes rather than a generic failure.
Correzioni
  • Fixed misleading authentication error messages during first-user setup and two-factor login, and hardened client-side parsing of server error responses.
  • Fixed intermittent ECDSA signature verification failures caused by an ASN.1 integer-encoding error.
  • Fixed a PKCS#11 locking issue where signing and certificate-lookup operations on the same token were not serialized, which could cause spurious "user already logged in" errors.
  • The SMTP password is no longer cleared when email settings are saved without entering a new password.
  • The user-account popup in the store-certificate registration dialog now closes only when its buttons are clicked, rather than on any outside click.
  • The Display Name field is now correctly optional during external-login setup, with its form label linked correctly.
  • Infrastructure:
    • Updated the .NET SDK to v10.0.301.
    • Third-party package updates.
Signotaur v1.2.0.10723 apr 2026
Funzionalità
  • Remote Desktop Protocol (.rdp) file signing is now supported, including timestamping and verification.
  • The server now returns the certificate chain with each signing certificate, removing the client's dependency on AIA fetching in firewalled or air-gapped environments.
  • CMS, NuGet, VSIX and RDP files are now signed in parallel within a batch for faster throughput.
  • The --separate-timestamp option is now respected when signing CMS, NuGet, VSIX and RDP files, not just Authenticode files.
  • New DSA certificate registrations are now rejected. DSA was withdrawn by NIST FIPS 186-5 and is no longer validated by code-signing runtimes. Existing registered DSA certificates continue to work.
  • A warning is now shown when an ECDSA certificate is used with --add-sha1-signature, as Authenticode dual-signing with ECDSA primary signatures is not supported by the Microsoft Trusted Root Program.
  • Warnings are now shown when CLI options are passed but have no effect on the specified file types.
  • Infrastructure:
    • Updated .NET SDK to v10.0.202.
    • Third-party package updates.
Correzioni
  • Fixed the server web UI footer showing "Forbidden" for non-administrator users.
Signotaur v1.2.0.801 apr 2026
Funzionalità
  • NuGet package (.nupkg) and Visual Studio extension (.vsix) signing is now supported, including timestamping and comprehensive verification.
  • Added CMS/PKCS#7 signing support for .mobileconfig, .mobileprovision, .provisionprofile and other non-Authenticode file types.
  • Certificates without a matching private key or Code Signing EKU are now rejected at registration.
  • Unsuitable PKCS#11 certificates are shown greyed out with warnings in the certificate selection UI.
  • A warning is now displayed when signing MSI files without --description, which can cause a cryptic publisher name in Windows UAC prompts.
  • New '--unsupported-file-types' (--uf) option controls how unrecognised file types are handled during signing and verification.
  • Infrastructure:
    • Moved ClickOnce/VSTO manifest signing from server to client, reducing the server's reliance on Windows-only native code.
    • General improvements to error handling.
    • Updated .NET SDK to v10.0.201.
    • Third-party package updates.
Correzioni
  • Fixed certificate key type and size not showing immediately after registering a new certificate.
  • Fixed database warning caused by an unnecessary transaction in API key lookup.
Signotaur v1.2.0.6310 mar 2026
Funzionalità
  • Added scheduled database backups, configurable via a new Backup settings page.
  • Added --renew [DURATION] and --allow-validity-reduction options to the rotate-key command for API key renewal workflows. --renew extends the new API key's expiry instead of inheriting the old key's expiry, with an optional validity duration, while --allow-validity-reduction permits rotation even when the new key would have a shorter validity period than the original.
  • Added option to test web configuration post-installation from the installer.
  • Added post-expiry reminder interval for certificate expiration notifications. This is configurable via the Notifications settings page and replaces the previous fixed daily post-expiry notification, and defaults to 28 days.
  • Added log file retention policy, configurable via the Logging settings page.
  • Added Last Used column and auto-revoke date/time hover tooltip to the API Keys table.
  • Settings and profile pages now warn before navigating away from unsaved changes.
  • Made some UI improvements on settings pages.
Correzioni
  • Fixed sorting issue on certificate tables with multiple pages.
  • Fixed over-zealous validation on the External Auth settings page.
Signotaur v1.2.0.4226 feb 2026
Funzionalità
  • Added '--if-expiring-within' option to the rotate-key command to only rotate keys that are approaching expiry within a specified duration (e.g., 7d, 24h, 1w). Added '--ignore-already-rotated-error' option to suppress errors when a key has already been rotated.
  • The installer now provides backup options during upgrades, allowing users to choose to back up the database, configuration, and certificates before the upgrade proceeds.
  • When a signing request specifies an unsupported algorithm, the server now logs the list of supported algorithms alongside the error, making it easier to diagnose configuration issues.
  • Infrastructure
    • Updated third-party dependencies to the latest stable versions.
Signotaur v1.2.0.3111 feb 2026
Funzionalità
  • New Commands
    • Added new config command with subcommands (init, set, get, show, unset, path) to persist defaults in %USERPROFILE%\.signotaur\config.json. Supported settings include server URL, certificate selectors (thumbprint/label/subject), console theme, output encoding, and allowUntrusted. Command-line arguments override environment variables, which override config file values.
    • Added new rotate-key command to rotate API keys with a configurable overlap period (0–30 days). During overlap, both keys remain valid; the old key is automatically revoked at expiry. This enables planned credential rollover with minimal client disruption. A new ApiKeyRotator role controls who can perform rotations.
    • Added new auth set-key command which securely stores API keys to files with owner-only permissions. This supports reading keys from stdin or via environment variables. Optional server verification ensures the key is valid before storing. The key file can then be used as input to other commands.
    • The rotate-key command supports direct output to CI systems like Continua CI server via the --emit-secret option. Alternatively, the --write-key-file or --write-env-file options can be used to update key files with the new API key atomically.
  • Sign Command
    • Added new --api-key-file option that allows the API key to be provided via a file instead of the command line. Supports both plain-text files and dotenv format.
    • Added new --api-key-name option that specifies a custom environment variable name or key when reading from a dotenv file (default: SIGNOTAUR_API_KEY).
    • Added new --fai`l-if-expiring-within option that checks API key expiry before signing and fails if the key expires within the specified duration (e.g., 7d, 24h, 1w). Useful for CI/CD pipelines to catch expiring keys early.
    • The SIGNOTAUR_SERVER environment variable can now be used as a fallback for the server URL when --sign-server is not specified.
    • Added new --label option to select certificates by label. When multiple certificates share the same label, the one with the latest expiry is automatically selected, simplifying certificate renewal workflows.
  • Web UI
    • The certificate page in the Admin section has a new Edit Certificate dialog. This allows editing the certificate alias and also assigning a label to the certificate. The label provides a stable logical identifier as an alternative to thumbprints, so expiring certificates can be replaced without updating client configuration.
    • The Users table in the Admin section has a new Manage API Keys dialog. This allows administrators to select users' API keys to revoke. The server now tracks when API keys were created and last used, and these details are shown next to each key. Each user can now be assigned to the ApiKeyRotator role in the Edit User Dialog.
    • All revoked and expired API keys can now be cleaned up on the API Keys page in the user's Profile section of the Web UI.
    • Added name and avatar of current logged-in user to the header.
    • Page sizes for tables with paging can now be set in the configuration file.
  • Improvements
    • Certificate selection by subject now chooses the certificate with the latest expiry when multiple certificates match, rather than returning an error.
    • Added short option aliases for all command-line options.
    • Certificate selection logging now shows which selector (thumbprint, label, or subject) was used when multiple were provided. Note selection precedence is: thumbprint > label > subject.
    • Added daily limit to configuration file for API key rotations.
    • Now intercepting more Windows error codes to log friendly error messages on client.
    • Client error output is now cleaner, with stack traces only shown in verbose mode.
    • Improvements to database connections and transactions in multiple threading scenarios.
  • Infrastructure
    • Updated the .NET runtime to version 10.0.3.
    • Updated third-party dependencies to the latest stable versions.
Correzioni
  • Security Fixes
    • Fixed a vulnerability due to Windows services requiring service paths to be quoted.
    • Added signature verification for client update manifests to prevent tampering by man-in-the-middle attacks.
  • Bug Fixes
    • Fixed issue with certificate enabled state not being updated correctly without refreshing the page.
    • Fixed paging issue on admin users table.
    • Fixed issue where avatar was not displayed in admin users table.
    • Fixed issue where debug logging would be displayed in some cases when verbose mode was not enabled.
    • Fixed issue where Create User dialog was not cleared on close.
Signotaur v1.1.0.8914 gen 2026
Funzionalità
  • The server now sends email notifications to API key owners when keys are approaching expiration or have expired. Notification timing is configurable in server settings.
  • Users can now control which types of email notifications they receive (API keys, code signing certificates, website certificates) from their profile settings.
  • The command-line client now displays warnings when an API key is approaching expiration, helping prevent authentication failures.
  • Added a new --theme option to customize console colours (light/dark/general), along with a --no-color option to disable colored output for CI/CD compatibility.
  • Improved robustness when working with PKCS#11 hardware security modules, including automatic recovery from session failures, library re-initialization on errors, and improved thread safety.
  • Added new Windows error descriptions, making it easier to diagnose signing failures.
  • Infrastructure:
    • Updated the .NET runtime to version 10.0.2.
    • Updated third-party dependencies to the latest stable versions.
Correzioni
  • Corrected a problem that prevented notification settings from being saved correctly.
  • Fixed an issue where cancelled operations did not return the correct exit codes.
