Supported encryption algorithms

The following tables contain all the encryption algorithms you can configure One Identity Safeguard for Privileged Sessions (SPS) to recognize. If you use a configuration that is only partially supported, SPS might ignore the connection without warning.

NOTE:

Do not use the CBC block cipher mode, or any sha1-based KEX, MAC, or host key algorithm, which are considered weak.

Key exchange algorithms

The default SPS configuration for both the client and the server is the following:

ecdh-sha2-nistp256,ecdh-sha2-nistp384,ecdh-sha2-nistp521,diffie-hellman-group-exchange-sha256,diffie-hellman-group16-sha512,diffie-hellman-group18-sha512,diffie-hellman-group14-sha256

The following key exchange (KEX) algorithms are recognized:

Figure 224: Key exchange (KEX) algorithms

Key exchange (KEX) Default Comment
ecdh-sha2-nistp256  
ecdh-sha2-nistp384

diffie-hellman-group18-sha512

During an SSH session, SPS performs a key re-exchange after each gigabyte of transmitted data or after each hour of connection time, whichever comes sooner.

Cipher algorithms

The default SPS configuration for both the client and the server is the following:

aes128-ctr,aes192-ctr,aes256-ctr

The following cipher algorithms are recognized:
