1.3.6.1.4.1.5624.1.2.26.1.3.2
Specifies the MAC (Message Authentication Code) algorithm
to use for data integrity verification. Currently enumerated
types, hmacSha1, hmacSha1Dash96, hmacMd5, hmacMd5Dash96,
hmacRipemd160, and hmacRipemd160Dash96 are supported, of
which hmacSha1, hmacSha1Dash96, hmacMd5, and hmacMd5Dash96 are
included in all distributions. Special values to this option
are anyStdMac, that allows only standard (see below) MACs,
and anyMac that allows either any available MAC or excludes
none but allows all others. AnyStdMac is the same as above,
but includes only those MACs mentioned in the IETF-SecSH-draft
(excluding none).
