aiootp is an aiootp - an asynchronous pseudo-one-time-pad based crypto and anonymity library.
Affected versions of this package are vulnerable to Information Disclosure. xor
& axor
functions that define the one-time-pad cipher had a vulnerability where it could leak <1-bit of plaintext. The issue was in the way keys were built, where the multiplicative products of two key segments were xor
'd together. This led to keys being slightly more likely to be positive integers, meaning the final bit had a greater than 1/2 probability of being a 0.
