(Chilkat2-Python) Sign XML to Create P7SDemonstrates how to sign XML to create a P7S.
import sys import chilkat2 # This example assumes the Chilkat API to have been previously unlocked. # See Global Unlock Sample for sample code. crypt = chilkat2.Crypt2() cert = chilkat2.Cert() success = cert.LoadPfxFile("qa_data/pfx/cert_test123.pfx","test123") if (success != True): print(cert.LastErrorText) sys.exit() # Tell the crypt component to use this cert. success = crypt.SetSigningCert(cert) if (success != True): print(crypt.LastErrorText) sys.exit() # The CadesEnabled property applies to all methods that create PKCS7 signatures. # To create a CAdES-BES signature, set this property equal to true. crypt.CadesEnabled = True crypt.HashAlgorithm = "sha256" # We can sign any type of file, creating a .p7s as output. # The .p7s contains the signature and also embeds the data of the file that is signed. inFile = "qa_data/xml/sample1.xml" p7sFile = "qa_output/sample1.xml.p7s" # Create the CAdES-BES attached signature, which contains the original data. # Note: Chilkat's function naming is not accurate. CreateP7M creates a PKCS7 signature where the signed file # is contained within the signature. CreateP7S creates a detached PKCS7 signature where the signed file # is NOT contained within the signature. We want the data to be contained in the signature, therefore # we call CreateP7M even though we are naming our output file .p7s. success = crypt.CreateP7M(inFile,p7sFile) if (success == False): print(crypt.LastErrorText) sys.exit() # Verify the .p7s file and extract the original file from the .p7s. extractedToFilePath = "qa_output/sample1.xml" success = crypt.VerifyP7M(p7sFile,extractedToFilePath) if (success == False): print(crypt.LastErrorText) sys.exit() print("Success!") |
