November 8, 2023
PowerTCP SSH and SFTP for .NET 7.0.0.3 adds support for RSA-SHA2-256/384/512 host key algorithms, providing stronger protection against cryptographic attacks.

PowerTCP SSH and SFTP for .NET by Dart Communications is a comprehensive suite of SSH-2 and SFTPv3 components for the .NET Framework, providing developers with the tools they need to add secure remote access and file transfer capabilities to their applications.

The 7.0.0.3 release bolsters server security with support for RSA-SHA2-256, RSA-SHA2-384, and RSA-SHA2-512 host key algorithms. This technology offers stronger protection against cryptographic attacks compared with the previously used RSA-SHA1. By employing these enhanced algorithms, you can effectively safeguard your servers from a range of sophisticated attacks, including collision, preimage, and second preimage attacks.
