Hi,
I have made the modifications you suggested and run the sample code for
RSA_public_decrypt. I get the same error that I receive with RSA_verify-
"error:0306E06C:bignum routines:BN_mod_inverse:no inverse".
Do you have any further suggestions? I do not understand what I am doing
wrong.
Thank

SignedInfo element?
Thank you for your continued help.

Hi, thanks again for your help.
I am now consistently getting an error "0306E06C:bignum
routines:BN_mod_inverse:no inverse" when calling RSA_verify.
I am still taking the following steps:
1) Extracting the 'SignedInfo' node and creating a 20 byte SHA1 hash of the
value of it and its contents

Not exactly, mo
I am still having a problem running RSA_verify which returns 'Data too large
for modulus' errors. If I check the big number value of the 'signatureValue'
and 'Modulus' they are 268628280 and 268628488 respectively which obviously
explains the error I am receiving. I have changed my code from using
I have modified this and am passing the Base64 decoding length to Bn_bin2bn
but I still get "data too large for modulus" errors. The modulus is 128
bytes, the exponent 3 bytes and the signature value 128 bytes. The message
digest is 20 bytes.
Is there anything else I can check?
Thanks

Thank you for your response.
I am Base64 decoding the signatureValue, modulus and exponent but if I check
the exponent length it is zero after decoding. The modulus length seems to
vary after decoding maybe because there is a null in the buffer. I think
that my Base64 decoding code is working ok

Hi
Thank you for your response and my apologies for not replying sooner- I was
drafted from one project to another and have only just returned to this one.
I am still having some trouble with this however.
I have attempted to ensure that both the modulus and signature are 128 bytes
long but I st

Hi all,
I have a .Net webservice sending a Digital Signature within the soap
response which I am attempting to verify using the Crypto library
'RSA_verify' function on an embedded MontaVista system. I am assuming that
this is possible to do.
I have extracted the 'SignedInfo' element from the xm
