[enable | disable]
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
