Jim Utter updated WSS-239:
--------------------------
Description:
Per the oasis spec, the UsernamePassword is summarized by the algorithm:
base64(sha-1(nonce+created+password))
But, in some scenarios you don't store cleartext passwords - only the sha-1 hash
of them. The oasis spec allows this via what they claim as "..password
equivalent". The problem I'm running into is that the password equivalent
is sha-1(password) or ultimately this equivalent:
base64(sha-1(nonce+created+sha-1(password)))
When the applicability of this approach was questioned to the oasis list,
they confirmed it:
http://lists.oasis-open.org/archives/wss-dev/201006/msg00003.html
But, when using the wss4j WSPasswordCallback mechanism, the call expects the
password to be a string but the binary output of the digest if converted to
a string, then back to the bytes (by UsernameToken.doPasswordDigest()) does
not result in the original byte array - causing any digest calculations to
fail.
This was originally posted in the mailing list below where Colm suggested I
provide a patch:
