Add PSK support to pyOpenSSL

Project description

pyopenssl-psk

Add PSK support to pyOpenSSL.

Installation

$ pip install pyopenssl-psk

API

Patch Method

  • patch_context()

    Add PSK related methods to the OpenSSL.SSL.Context class.

from openssl_psk import patch_context

patch_context()

Server Methods

  • Context.use_psk_identity_hint(hint: bytes) -> None

    Set the server PSK identity hint.

  • Context.set_psk_server_callback(callback: server_callback) -> None

    Set a callback to populate the server PSK.

    server_callback(connection: Connection, client_identity: bytes) -> psk: bytes

    User provided callback function to populate the connection PSK.

from OpenSSL.SSL import Context, Connection, TLSv1_2_METHOD

PSK_MAP = {
    b'pre_shared_key_identity': b'pre_shared_key',
}

def server_callback(conn, client_identity):
    return PSK_MAP[client_identity]

ctx = Context(TLSv1_2_METHOD)
ctx.set_cipher_list(b'PSK')
ctx.use_psk_identity_hint(b'pre_shared_key_identity_hint')
ctx.set_psk_server_callback(server_callback)
server = Connection(ctx)

Client Methods

  • Context.set_psk_client_callback(callback: client_callback) -> None

    Set a callback to populate the client PSK identity and PSK.

    client_callback(connection: Connection, identity_hint: bytes) -> tuple(psk_identity: bytes, psk: bytes)

    User provided callback function to populate the connection PSK identity and PSK.

from OpenSSL.SSL import Context, Connection, TLSv1_2_METHOD

def client_callback(conn, identity_hint):
    return (b'pre_shared_key_identity', b'pre_shared_key')

ctx = Context(TLSv1_2_METHOD)
ctx.set_cipher_list(b'PSK')
ctx.set_psk_client_callback(client_callback)
client = Connection(ctx)

See OpenSSL.SSL documentation for more information.
