Hi
I will ask for the code, I have not tried using OpenSSL after base64 encoding it is supposed to be 172 characters because the key length is 1024 bits, however using SSF_KRN_SIGN i am getting a signature of 360 bytes when i test using program SSF01 . On the other hand if i use SSFW_KRN_SIGN the sinature always is 172 characters after base64 encoding but then the bank says the signature is wrong so i think its possibly that SSFW_KRN_SIGN uses format PKCS#1-V1.5 and the bank had specified that we use PKCS7.
Regards
