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 Chris ______________________________________________________________________ OpenSSL Project http://www.openssl.org User Support Mailing List openssl-users@openssl.org Automated List Manager [EMAIL PROTECTED]
