Authenticode Sign using Smartcard or USB Token

See more Code Signing Examples

Demonstrates how to Authenticode sign an EXE or DLL using a smartcard or USB token, such as a Yubikey.

Note: Chilkat's code signing class was added in v9.5.0.97

# 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 = chilkat.CkJsonObject()
json.UpdateString("hashAlg","sha256")
json.UpdateBool("timestampToken.enabled",True)
json.UpdateString("timestampToken.tsaUrl","http://timestamp.digicert.com")
json.UpdateBool("timestampToken.requestTsaCert",True)
json.UpdateString("timestampToken.hashAlg","sha256")

# 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 = chilkat.CkCert()

# Yubico YubiKey OTP+FIDO+CCID 0, default PIN = 123456
cert.put_SmartCardPin("123456")

# Assuming you have the Yubikey inserted into the USB on the computer...
# and there is only 1 signing certificate on the Yubikey, then just load from
# the "smartcard".  (assuming you don't have additional smartcards or USB tokens plugged in)
success = cert.LoadFromSmartcard("")
if (success == False):
    print(cert.lastErrorText())
    sys.exit()

# If the smartcard/token has several possible certificates that can be used for signing,
# then see the online documentation for the LoadFromSmartcard method,
# and also see the online documentation and examples for Chilkat Pkcs11 and ScMinidriver.
# There are many possible ways to load a Chilkat certificate object with a cert (and associated private key)
# from a variety of sources.  The only coding difference for any signing function in Chilkat,
# whether it be a PDF, XmlDSig, CMS, etc. is in how the cert is loaded.

# You can sign .exe or .dll files.
exePath = "C:/someOtherDir/HelloWorld.exe"

signer = chilkat.CkCodeSign()

# If successful, the following call will apply the signature to the EXE (or DLL).
success = signer.AddSignature(exePath,cert,json)
if (success == False):
    print(signer.lastErrorText())
    sys.exit()

print("Successfully applied the Authenticode signature.")
