> 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.
