             Project: WSS4J
          Issue Type: Bug
    Affects Versions: 1.5.7
            Reporter: Dobri Kitipov

Hi everybody,
there is a problem when when a message body is signed and then an XPath 
expression pointing to a body element is encrypted.
The problem is that the verification of the signature cannot pass. This is 
caused by the fact that there is a difference between the signed body and the 
body used for signature verification. The body used for signature verification 
is modified because after XPath element decryption an ID is added to the 
element. This ID is used to verify the decryption, but changes the original 
body. 

Exception thrown is:

[WARN] Verification failed for URI "#Id-11235685"
[WARN] Expected Digest: o0jyc1pJHEawRaLNry+cnYeCc80=
[WARN] Actual Digest: VMEF6KgvE6t3PNLlYR49LGEW+xM=
[ERROR] The signature or decryption was invalid
