Overview

aiootp is an aiootp - an asynchronous pseudo-one-time-pad based crypto and anonymity library.

Affected versions of this package are vulnerable to Cryptographic Issues. The HMAC verifiers on ciphertexts did not include the salt or pid values when deriving the HMAC. This associated data can therefore be changed to cause a party to decrypt a past ciphertext with a salt or pid of an attacker's choosing.
