You can install from PyPi.

❯ pip install py-libtrust

Example

Sign/Verify a jose-json-web-signature

import datetime
from libtrust.keys.ec_key import generate_private_key
from libtrust.jsonsign import JSONSignature

# Generate a EC P256 private key
ec_key = generate_private_key("P-256")

your_content = {
    "author": "shabbywu([e-mail])"
}

# New a JSONSignature
js = JSONSignature.new(your_content)

# signature
js.sign(ec_key, dt=datetime.datetime.utcfromtimestamp(0))

jws = js.to_jws()

loaded_js = JSONSignature.from_jws(jws)

assert js == loaded_js
assert js.verify() == loaded_js.verify()

Serialize/Deserialize a self-signed JSON signature

import json
import datetime
from libtrust.keys.ec_key import generate_private_key
from libtrust.jsonsign import JSONSignature

# Generate a EC P256 private key
ec_key = generate_private_key("P-256")

your_content = {
    "author": "shabbywu([e-mail])"
}

# New a JSONSignature
js = JSONSignature.new(your_content)

# signature
js.sign(ec_key, dt=datetime.datetime.utcfromtimestamp(0))

pretty_signature = js.to_pretty_signature("signatures")
loaded_js = js.from_pretty_signature(pretty_signature)

assert js.verify() == loaded_js.verify()
assert json.loads(pretty_signature)["author"] == "shabbywu([e-mail])"
