Chilkat2-Python

Code Signing using Sectigo USB Token

See more Code Signing Examples

Demonstrates how to Authenticode sign an EXE or DLL using a SafeNet USB token from Sectigo.

Requires Chilkat v10.0.0 or greater.

# This example requires the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

# First create the following JSON to specify that SHA256 is to be used,
# and provide timestamp server information.

# {
#   "hashAlg": "sha256",
#   "timestampToken": {
#     "enabled": true,
#     "tsaUrl": "http://timestamp.digicert.com",
#     "requestTsaCert": true,
#     "hashAlg": "sha256"
#   }
# }

json = chilkat2.JsonObject()
json.UpdateString("hashAlg","sha256")
json.UpdateBool("timestampToken.enabled",True)
json.UpdateString("timestampToken.tsaUrl","http://timestamp.digicert.com")

# The only difference in signing with a smartcard or USB token
# is that the cert is loaded from a smartcard or USB token, instead of a PFX or from elsewhere
# such as from the Windows certificate store.
cert = chilkat2.Cert()

# Use your USB token PIN (user password).
# It will be a string similar to this:  j6X54nB7-jlp5Cr2
cert.SmartCardPin = "j6X54nB7-jlp5Cr2"

# Load the certificate based on the serial number.
# *** Use your certificate's serial number.
success = cert.LoadFromSmartcard("serial=3FF5B69109BFD4046C92CC0D18EE23C2")
if (success == False):
    print(cert.LastErrorText)
    sys.exit()

# Note: If the above fails, then use the SafeNet Authentication Client Tools
# to login to your token using your token password.
# You don't want too many failed logins, otherwise you'll lock the token.
# A successful login will reset number of failed logins back to 0.

# Note: This is to sign Microsoft Windows executables or DLLs
# You can sign .exe or .dll files.
exePath = "C:/someDirectory/HelloWorld.exe"

signer = chilkat2.CodeSign()

# If successful, the following call will apply the signature to the EXE (or DLL).

    sys.exit()
