PowerTCP SSH and SFTP for .NET V8.0は、OpenSSHの"strict KEX"モードのサポートを追加することで、Terrapin攻撃に対する保護を強化

PowerTCP SSH and SFTP for .NET by Dart Communications is a robust component suite designed to simplify secure file transfer and remote shell access within .NET applications. Tailored for developers building enterprise-grade solutions, it offers a comprehensive implementation of the SSH (Secure Shell) and SFTP (Secure File Transfer Protocol) standards. With a focus on reliability and performance, the library supports advanced features such as asynchronous operation, persistent connections, and full control over session parameters. Whether you're automating secure file exchanges or integrating remote server access, PowerTCP SSH and SFTP provides the flexibility and security essential for modern .NET development.

The PowerTCP SSH and SFTP for .NET V8.0.0.0 update introduces support for OpenSSH's "strict kex" (key exchange) extension. This change directly addresses the security vulnerability exploited in Terrapin attacks - where weaknesses in the SSH protocol’s key exchange could be manipulated. By enforcing stricter key exchange validation, this enhancement ensures that the connection negotiation process is more resilient to tampering, significantly improving the overall security of SSH and SFTP sessions in .NET applications.

To see a full list of what's new in version 8.0.0.0, see our release notes.

PowerTCP SSH and SFTP for .NET is licensed per developer and is available as a perpetual license with 12 months subscription (product updates and priority email support). See our PowerTCP SSH and SFTP for .NET licensing page for full details.
