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. If an adversary can get a user to reveal the value returned by the hmac method when fed the tag file's filename & the salt used for that encrypted tag, then they could deduce the decryption key for the tag. This version check is here only for backwards compatibility & will be removed on the next update.
