I would change my word: the RSA signature MIGHT be different (and DSA is
However, I have to admit that in the XMLDSig case RSA signatures will be
because a const FF padding is used
Sorry for confusion, last time I read this spec few months ago and
I would recommend you to check that you use correct padding and the
in MS Cryptoapi. I would not be surprised if there are some flags needs
to be set.
There is not command line option to print out the digest before
signature but you can set
a break point in "xmlSecSignRsaSha1Sign" function in the rsa.c file just
before RSA_sign() call.
