Usage Examples¶
The following is a simple sample code using PySETO:
>>> import pyseto
>>> from pyseto import Key
>>> secret_key_pem = "-----BEGIN PRIVATE KEY-----\nMC4CAQAwBQYDK2VwBCIEILTL+0PfTOIQcn2VPkpxMwf6Gbt9n4UEFDjZ4RuUKjd0\n-----END PRIVATE KEY-----"
>>> public_key_pem = "-----BEGIN PUBLIC KEY-----\nMCowBQYDK2VwAyEAHrnbu7wEfAP9cGBOAHHwmH4Wsot1ciXBHwBBXQ4gsaI=\n-----END PUBLIC KEY-----"
>>> secret_key = Key.new("v4", "public", secret_key_pem)
>>> token = pyseto.encode(
... secret_key,
... '{"data": "this is a signed message", "exp": "2022-01-01T00:00:00+00:00"}',
... )
>>> token
B'v4.public.eyJkYXRhIjogInRoaXMgaXMgYSBzaWduZWQgbWVzc2FnZSIsICJleHAiOiAiMjAyMi0wMS0wMVQwMDowMDowMCswMDowMCJ9l1YiKei2FESvHBSGPkn70eFO1hv3tXH0jph1IfZyEfgm3t1DjkYqD5r4aHWZm1eZs_3_bZ9pBQlZGp0DPSdzDg'
>>> public_key = Key.new("v4", "public", public_key_pem)
>>> decoded = pyseto.decode(public_key, token)
>>> decoded.payload
B'{"data": "this is a signed message", "exp": "2022-01-01T00:00:00+00:00"}'
This page shows various examples to use PySETO.
v4.local¶
import pyseto
from pyseto import Key
key = Key.new("v4", "local", b"our-secret")
token = pyseto.encode(
key, '{"data": "this is a signed message", "exp": "2022-01-01T00:00:00+00:00"}'
)
decoded = pyseto.decode(key, token)
assert (
decoded.payload
== b'{"data": "this is a signed message", "exp": "2022-01-01T00:00:00+00:00"}'
)
assert decoded.footer == b""
assert decoded.version == "v4"
assert decoded.purpose == "local"
v4.public¶
import pyseto
from pyseto import Key
secret_key_pem = "-----BEGIN PRIVATE KEY-----\nMC4CAQAwBQYDK2VwBCIEILTL+0PfTOIQcn2VPkpxMwf6Gbt9n4UEFDjZ4RuUKjd0\n-----END PRIVATE KEY-----"
public_key_pem = "-----BEGIN PUBLIC KEY-----\nMCowBQYDK2VwAyEAHrnbu7wEfAP9cGBOAHHwmH4Wsot1ciXBHwBBXQ4gsaI=\n-----END PUBLIC KEY-----"
secret_key = Key.new("v4", "public", secret_key_pem)
token = pyseto.encode(
secret_key,
'{"data": "this is a signed message", "exp": "2022-01-01T00:00:00+00:00"}',
)
public_key = Key.new("v4", "public", public_key_pem)
decoded = pyseto.decode(public_key, token)
assert (
decoded.payload
== b'{"data": "this is a signed message", "exp": "2022-01-01T00:00:00+00:00"}'
)
assert decoded.footer == b""
assert decoded.version == "v4"
assert decoded.purpose == "public"
