class SSHCiphers: (source)
SSHCiphers represents all the encryption operations that need to occur to encrypt and authenticate the SSH connection.
Class Variable | cipherMap |
A dictionary mapping SSH encryption names to 3-tuples of (<cryptography.hazmat.primitives.interfaces.CipherAlgorithm>, <block size>, <cryptography.hazmat.primitives.interfaces.Mode>) |
Class Variable | macMap |
A dictionary mapping SSH MAC names to hash modules. |
Instance Variable | outCipType |
the string type of the outgoing cipher. |
Instance Variable | inCipType |
the string type of the incoming cipher. |
Instance Variable | outMACType |
the string type of the incoming MAC. |
Instance Variable | inMACType |
the string type of the incoming MAC. |
Instance Variable | encBlockSize |
the block size of the outgoing cipher. |
Instance Variable | decBlockSize |
the block size of the incoming cipher. |
Instance Variable | verifyDigestSize |
the size of the incoming MAC. |
Instance Variable | outMAC |
a tuple of (<hash module>, <inner key>, <outer key>, <digest size>) representing the outgoing MAC. |
Instance Variable | inMAc |
see outMAC, but for the incoming MAC. |
