摘要

from tsp_client import TSPSigner, TSPVerifier

# Sign a message online by transmitting its digest to the timestamp authority
message = b"abc"
signer = TSPSigner()
signed = signer.sign(message)  # Returns raw bytes of the verified timestamp token.

# Verify a presented timestamp token offline using the original message
verified = TSPVerifier().verify(signed, message=message)

# Or sign and verify using the message digest (digest algorithm may vary)
import hashlib

digest = hashlib.sha512(message).digest()

signer.sign(message_digest=digest)
verified = TSPVerifier().verify(signed, message_digest=digest)

print(verified.tst_info)  # Parsed TSTInfo (CMS SignedData) structure
print(verified.signed_attrs)  # Parsed CMS SignedAttributes structure

from tsp_client import TSPSigner, TSPVerifier, SigningSettings
signing_settings = SigningSettings(tsp_server="http://timestamp.identrust.com")
signer = TSPSigner()
signed = signer.sign(message, signing_settings=signing_settings)
