(Chilkat2-Python) Create PKCS1 RSA Signature with PEM Private KeySee more RSA ExamplesDemonstrates how to load a private key from a PEM file and create a PKCS1 RSA digital signature.Note: This example requires Chilkat v11.0.0 or greater.
import sys import chilkat2 success = False # This example assumes the Chilkat API to have been previously unlocked. # See Global Unlock Sample for sample code. pkey = chilkat2.PrivateKey() # Load the private key from an RSA PEM file: success = pkey.LoadPemFile("pvkey2_rsa.pem") if (success == False): print(pkey.LastErrorText) sys.exit() rsa = chilkat2.Rsa() # Import the private key into the RSA object: success = rsa.UsePrivateKey(pkey) if (success == False): print(rsa.LastErrorText) sys.exit() # Get the signature as hex. rsa.EncodingMode = "hex" strData = "This is the string to be signed." # Sign the string using the sha-1 hash algorithm. # Other valid choices are "md2", "md5", "sha256", # "sha384", and "sha512". hexSig = rsa.SignStringENC(strData,"sha-1") print(hexSig) print("Success!") |
