Python Requires Chilkat v11.7.0+

Authenticode Sign a VBScript File (.vbs)

See more Code Signing Examples

Demonstrates how to Authenticode sign a VBScript file (.vbs). Signing VBScript files requires Chilkat v11.7.0 or later. The signature is appended to the file as a comment block. Python

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

# Signing a VBScript file (.vbs) requires Chilkat v11.7.0 or later.

# Load the code signing certificate.  It must have access to its private key.
cert = chilkat2.Cert()
success = cert.LoadPfxFile("C:/someDir/myCodeSigningCert.pfx","pfx password")
if (success == False):
    print(cert.LastErrorText)
    sys.exit()

# Sign with SHA256, and ask a timestamp authority for a timestamp.  A timestamp lets the
# signature continue to validate after the code signing certificate has expired.

#   '' SIG '' MIIoKgYJKoZIhvcNAQcCoIIoGzCCKBcCAQExDzANBglg
#   '' SIG '' ...
#   '' SIG '' End signature block

# If the script is already signed, the new signature block replaces the existing one.

# Note: Other script types, such as JScript (.js), are not supported.
# AddSignature returns false for an unsupported file type and does not modify the file.
