Question:
I would like to ask straight to the point. How do I sign plain text and private key (.pfx) using Algorithm, Encoding and Key Length below. (PKCS #1 SHA-1 Encryption)
> Signature Algorithm: SHA1RSA Hash:
> SHA1 RSAKey Length: 2048 Signature
> encoding:Base64
Does this example help? Just change the "hex" encoding to "base64" and I think it will do what you want:
