Yes, I know the hash will be calculated when generating a signature. 
However, it will be troublesome since at least a private key and a 
certificate will be needed. ( I tried to use RSA_NONE when calling 
createBlankSignature, but I've got No signing algorithm exception 
afterwards).

Actually there's a API class XSECC14n20010315 can do the 
canonicalization job, which is just not well documented. I found a 
sample binary "c14n" in xml-security-c source code and it's actually 
very easy. Now I've got correct result.

Thank you all.
