Nessus vulnerability scanner reported – SSH Weak Key Exchange Algorithms Enabled and SSH Server CBC Mode Ciphers Enabled. The detailed message suggested that the SSH server allows key exchange algorithms which are considered weak and support Cipher Block Chaining (CBC) encryption which may allow an a...
The security scan shows a week Key Key Exchange Algorithm which needs to be removed from ssh configuration:SSH Server Supports Weak Key Exchange AlgorithmsCVSS Score: 4.30Description: The server supports one or more weak key exchange algorithms. It is highly adviseable to remove weak key exchange...
For example, old clients that only support those weak algorithms may not connect with a new SSH server. Let’s see an example of a compatibility issue arising from a cipher mismatch. Suppose, we’ve got a server with supported ciphers asaes128-ctr,aes192-ctr,aes256-ctr,andaes128-cbc: ...

However, the SchUseStrongCrypto key wasn't created. So after we establish the TCP/IP session, the ClientHello should be sent by having these conditions: .NET by using weak cryptography (only TLS 1.0 and earlier versions) SChannel configured to use only TLS 1.1 or later versions Resolution...
