(Ruby) RSA Sign utf-8 Byte Representation of StringDemontstrates how to sign the utf-8 byte representation of a string. Note: This example requires Chilkat v11.0.0 or greater.
require 'chilkat' success = false # This example requires the Chilkat API to have been previously unlocked. # See Global Unlock Sample for sample code. # Load an RSA private key for signing. privKey = Chilkat::CkPrivateKey.new() success = privKey.LoadEncryptedPemFile("qa_data/pem/rsa_passwd.pem","passwd") if (success == false) print privKey.lastErrorText() + "\n"; exit end rsa = Chilkat::CkRsa.new() success = rsa.UsePrivateKey(privKey) if (success == false) print rsa.lastErrorText() + "\n"; exit end originalData = "This is the string to be hashed an RSA signed." # Indicate that we want the utf-8 byte representation of the string to be signed rsa.put_Charset("utf-8") # We want the RSA signature in base64 format rsa.put_EncodingMode("base64") sigBase64 = rsa.signStringENC(originalData,"sha256") print sigBase64 + "\n"; |
