Detailed Description

MS-CHAPv2 password hash.

MS-CHAPv2 calculates the MD4 digest of an unspecified two-byte little-endian Unicode encoding (presumably either UCS-2LE or UTF-16LE) of the password.

For constructing the challenge response, the MD4 digest is then zero-padded to 21 bytes and used as three separate 56-bit DES keys.

For constructing the authenticator response, the MD4 digest is then used as an input to a SHA-1 digest along with the NT response and a magic constant.
