Description
This command is used to configure SSH service algorithm.
Format

Parameters
3DES - The "3DES" cipher is three-key triple-DES (encrypt-decrypt-encrypt), where the first 8
bytes of the key are used for the first encryption, the next 8 bytes for the decryption, and the
following 8 bytes for the final encryption.
AES (128,192,256) - Advanced Encryption Standard.
arcfour - RC4 (also known as ARC4 or ARCFOUR meaning Alleged RC4) is the most widely-
used software stream cipher.
blowfish - Blowfish is a keyed, symmetric block cipher.
cast128 - CAST-128 is a 12- or 16-round feistel network with a 64-bit block size and a key size of
between 40 to 128 bits.
twofish (128,192,256) - Twofish has a 128-bit block size, a key size ranging from 128 to 256 bits.
MD5 - Message-Digest Algorithm 5.
SHA1 - Secure Hash Algorithm.
RSA - RSA encryption algorithm is a non-symmetric encryption algorithm.
DSS - Digital Signature Standard.
enable - Enabled the algorithm.
disable - Disables the algorithm.
Restrictions
Only Administrator, Operator and Power-User level users can issue this command.
