Introduction In the dynamic landscape of cybersecurity, vigilance is key. A recent study has highlighted a vulnerability known as “Passive SSH Key Compromise,” which poses risks to SSH connections through certain RSA key signature generation flaws. At Jadaptive, we prioritize your security and have conducted a comprehensive analysis of our products in light of this […]
This release contains bug fixes and minor feature enhancements. OpenSSH Certificate Bug A bug in processing extensions in OpenSSH Certificates caused authentication failures when custom extensions were present in the certificate. Improved Remote Hashing We have implemented the SFTP extensions “check-file-name” and “check-file-handle” to improve the existing support of MD5 hashes to include SHA-1, SHA-256 […]

After upgrading your OpenSSH client or your OS distribution, you may encounter this error when connecting to your SSH servers. What does “no matching host key type found” mean? When establishing an SSH connection, the client uses the host key of the SSH server to verify the information the server has provided, which it does […]
In 2019, I answered a question on StackOverflow on converting an OpenSSH Private Key to an RSA Private Key. Recently I had an inquiry about this, so I thought it would be helpful to document for others the exact steps required to perform the conversion in Java using the Maverick Synergy Java SSH API. https://stackoverflow.com/questions/56900615/how-to-convert-openssh-private-key-to-rsa-private-key-in-java […]
This minor update contains a customer support related bug fix, support for the new PuTTY Private Key format and a new public/private key implementation. PuTTY Private Keys Introduced in version 0.75, version 3 of the PuTTY Private Key File Format uses an Argon2 key derivation function incompatible with our previous implementation. This update includes support […]
This release includes minor bug fixes to the Adaptive Configuration files’ match directive support and a new PuTTY Private Key files implementation. PuTTY Private Keys Introduced in version 0.75, version 3 of the PuTTY Private Key File Format uses an Argon2 key derivation function incompatible with our previous implementation. This update includes support for version […]
This release is primarily a bug fix release. Upload Performance During performance testing, we discovered that the default configuration of the SFTP server created a bottleneck in upload performance. Several configuration changes could quickly mitigate the problem, such as changing the SFTP block size on the client or enabling TCP_NODELAY on the server. However, the […]
This release is primarily a bug fix release. Azure SFTP compatibility A compatibility issue exists in previous versions with the Azure SFTP service. The remote server terminates the connection if you connect to the service with a hyphen in the Software/Version/Comments field of the SSH identification string. The identification string is now further sanitised before […]
