    Resolution: Not A Problem

Hi Colm,

you are right, seems I was too fast to write a bug report before doing a good old \
debug and especially carefully checking the certificates that are compared. Sorry for \
taking your time.

> CryptoBase.getAliasForX509CertThumb calculates hash wrongly, could only match first \
>                 certificate correctly
> ---------------------------------------------------------------------------------------------------------
>  
> Key: WSS-330
> URL: https://issues.apache.org/jira/browse/WSS-330
> Project: WSS4J
> Issue Type: Bug
> Components: WSS4J Core
> Affects Versions: 1.5.12
> Reporter: Maxim Naidenov
> Assignee: Colm O hEigeartaigh
> Fix For: 1.5.13
> 
> 
> The method CryptoBase.getAliasForX509CertThumb(byte[] thumb) does not calculate the \
> hash of certificates in the keystore correctly and could possibly match only the \
> first certificate. This is because the SHA1 message digest is reset once:
> sha = MessageDigest.getInstance("SHA-1");
> sha.reset();
> but is updated every time while enumerating over certificates in the keystore:
> sha.update(cert.getEncoded());
> byte[] data = sha.digest();
> The fix would be to move the digest reset in the beginning of the enumeration loop.
