DES and Triple DES EDE cipher algorithms

These are ‘Null’ algorithms, used by IPsec, which do nothing.

Это Null алгоритм, используемый IPsec и ничего более.

MD4 digest algorithm

MD4 message digest algorithm (RFC 1320).

SHA1 digest algorithm

SHA-1 secure hash standard (FIPS 180-1/DFIPS 180-2).

SHA256 digest algorithm

SHA256 secure hash standard (DFIPS 180-2).

This version of SHA implements a 256 bit hash with 128 bits of security against collision attacks.
