H Insufficient Entropy aiootp is an aiootp - an asynchronous pseudo-one-time-pad based crypto and anonymity library. Affected versions of this package are vulnerable to Insufficient Entropy such that the top-level '(a)csprng' functions were found to be unsafe in concurrent code, leading to the possibility of producing identical outputs from distinct calls if run in quick succession from concurrently running threads & co-routines. Note: This vulnerability does not effect users of the library which are not running it in multiple concurrent threads or co-routines. How to fix Insufficient Entropy?

M Cryptographic Issues 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 new StreamHMAC class ensures the user must contend with ciphertext validation even when using the `_encipher`, `_decipher` & `_xor` Comprende generators. All usages of the `generics.py` hmac functions are impacted by a reordering of the key & argument within those functions to more closely mirror the reasoning behind the HMAC spec. The main `a/_keys` generators used by the pseudo one time pad cipher has been altered to patch a flaw in its design described in `CHANGES.rst`.

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.

M Cryptographic Issues 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. How to fix Cryptographic Issues?

M Information Disclosure 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. How to fix Information Disclosure? Upgrade `aiootp` to version 0.13.0 or higher.	[,0.13.0)

Insufficient Entropy

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

Affected versions of this package are vulnerable to Insufficient Entropy such that the top-level '(a)csprng' functions were found to be unsafe in concurrent code, leading to the possibility of producing identical outputs from distinct calls if run in quick succession from concurrently running threads & co-routines.

Note: This vulnerability does not effect users of the library which are not running it in multiple concurrent threads or co-routines.
