Functions¶

`create_authenticator`(name, **kwargs)	Accepts various keys and values to configure an authenticator. The
`generate_totp_secret`([length])	Generates a new Base32 encoded, random secret.
`compute_totp`(secret[, offset])	Computes the current TOTP code.
`check_totp`(secret, ticket)	Check a TOTP value received from a principal trying to authenticate against
`qrcode_from_totp`(secret, label, issuer)
`pbkdf2`(data, salt[, iterations, keylen, hashfunc])	Returns a binary digest for the PBKDF2 hash algorithm of `data`
`derive_key`(secret, salt[, iterations, keylen])	Computes a derived cryptographic key from a password according to PBKDF2.
`generate_wcs`([length])	Generates a new random secret for use with WAMP-CRA.
`compute_wcs`(key, challenge)	Compute an WAMP-CRA authentication signature from an authentication
`derive_scram_credential`(→ Dict)	Derive WAMP-SCRAM credentials from user email and password. The SCRAM parameters used

autobahn.wamp.auth.create_authenticator(name, **kwargs)[source]¶

Accepts various keys and values to configure an authenticator. The valid keys depend on the kind of authenticator but all can understand: authextra, authid and authrole

Returns: an instance implementing IAuthenticator with the given configuration.

class autobahn.wamp.auth.AuthScram(**kw)[source]¶

Bases: object

Implements “wamp-scram” authentication for components.

NOTE: This is a prototype of a draft spec; see https://github.com/wamp-proto/wamp-proto/issues/135

property authextra¶

name = scram¶

on_challenge(session, challenge)[source]¶

on_welcome(session, authextra)[source]¶

When the server is satisfied, it sends a ‘WELCOME’ message.

This hook allows us an opportunity to deny the session right before it gets set up – we check the server-signature thus authorizing the server and if it fails we drop the connection.

class autobahn.wamp.auth.AuthWampCra(**kw)[source]¶

Bases: object

property authextra¶

name = wampcra¶

on_challenge(session, challenge)[source]¶

on_welcome(msg, authextra)[source]¶

autobahn.wamp.auth.generate_totp_secret(length=10)[source]¶

Generates a new Base32 encoded, random secret.
