SSLBlackbox .NET Client-Server - Vendor

SSLBlackbox package of SecureBlackbox
SSL protocol was originally introduced by Netscape to secure access to Internet sites. Since then, SSL was adopted by Internet community for securing network communications in Internet and Intranet networks as TLS (Transport Layer Security) protocol.

With SSLBlackbox you can connect to remote servers or build your own secure servers.

SSL/TLS is often used to secure application-level protocols, such as HTTP, FTP and SMTP. SSLBlackbox includes components for client-side access to the remote servers using these protocols.

In particular, SSLBlackbox includes a client-side component to upload and download files using FTP / FTPS protocol. Other operations defined by FTP protocol specifications are supported as well. Note: FTPS (FTP over SSL) is not SFTP, which is SSH File Transfer Protocol and which is available in SFTPBlackbox package.

One of the recent additions to SSL/TLS family of protocols is Datagram TLS ( DTLS ), which is very similar to TLS. DTLS is used to protect UDP-based or other message-based network communications such as stream audio and video delivery. SSLBlackbox is one of the few solutions to provide client-side and server-side DTLS support.

Unlike symmetric encryption, securing communications with SSL/TLS doesn't require that the sides know the shared secret (password/encryption key). Also, the public key security (PKI) lets each side examine authenticity of the other side and prevent man-in-the-middle attacks. Another benefit of SSL/TLS is that PKI infrastructure is a widely-used technology, so implementation and maintenance of SSL/TLS-based solutions are quite simple tasks.

SSLBlackbox does not use CryptoAPI, OpenSSL or other third-party encryption library. For certificate creation, management and validation SSLBlackbox uses PKIBlackbox, base functions of which are included with SSLBlackbox package.

SSLBlackbox has been tested with numerous client-side and server-side SSL implementations, including Internet Information Server and Java 2 EE. SSLBlackbox includes special workarounds for SSL/TLS implementation flaws, found in this software.

SSLBlackbox is offered as an individual package and as a part of Professional, Standard and Transports packages.

SSL/TLS Protocol implementation contains the following features, common to both client-side and server-side components:
