The following helpers allow a user to maintain a set of private key materials based on a potentially weak (locking) password (or PIN), and is based on Argon2id and HKDF:
- :meth:`stretch_argon2_secret <autobahn.xbr.stretch_argon2_secret>`
- :meth:`expand_argon2_secret <autobahn.xbr.expand_argon2_secret>`
- :meth:`pkm_from_argon2_secret <autobahn.xbr.pkm_from_argon2_secret>`
The following helpers allow to use a TOTP based 2nd factor for authentication purposes:
- :meth:`generate_totp_secret <autobahn.wamp.auth.generate_totp_secret>`
- :meth:`compute_totp <autobahn.wamp.auth.compute_totp>`
- :meth:`check_totp <autobahn.wamp.auth.check_totp>`
- :meth:`qrcode_from_totp <autobahn.wamp.auth.qrcode_from_totp>`
Write me.
The following helpers provide auxiliary functions used with WAMP-XBR authentication:
- :meth:`xor <autobahn.util.xor>`
- :meth:`generate_token <autobahn.util.generate_token>`
- :meth:`machine_id <autobahn.util.machine_id>`
The following helpers allow WAMP clients to authenticate using WAMP-cryptosign which is based on Ed25519:
- :class:`AuthCryptoSign <autobahn.wamp.auth.AuthCryptoSign>`
- :class:`SigningKey <autobahn.wamp.cryptosign.SigningKey>`
The following helpers allow WAMP clients to use end-to-end encrypted application payloads and data-encryption-key exchange transactions signed using an Ethereum private key, and anchored on-chain (indirectly via a off-chain state channel):
- :meth:`generate_seedphrase <autobahn.xbr.generate_seedphrase>`
- :meth:`check_seedphrase <autobahn.xbr.check_seedphrase>`
- :meth:`account_from_seedphrase <autobahn.xbr.account_from_seedphrase>`
