HTTP Digest Algorithm Values - per [RFC3230]
(last updated 2002-01-14)
Digest
Algorithm Description Reference
--------- ----------------------------------------- ---------
MD5 The MD5 algorithm, as specified in [RFC1321, RFC1521]
[RFC1321]. The output of this algorithm is
encoded using the base64 encoding [RFC1521].
SHA The SHA-1 algorithm [fip180-1]. The output [fip180-1, RFC1521]
of this algorithm is encoded using the
base64 encoding [RFC1521].
UNIXsum The algorithm computed by the UNIX ``sum'' [T912]
command, as defined by the Single UNIX
Specification, Version 2 [T912]. The output
of this algorithm is an ASCII decimal-digit
string representing the 16-bit checksum,
which is the first word of the output of the
UNIX ``sum'' command.
UNIXcksum The algorithm computed by the UNIX ``cksum'' [T912]
command, as defined by the Single UNIX
Specification, Version 2 [T912]. The output
of this algorithm is an ASCII digit string
representing the 32-bit CRC, which is the
first word of the output of the UNIX ``cksum''
command.
