Note: this is not asking for a personal viewpoint on what is the better library, but rather what is the "safest" library or what is a good indication of a "safe" library.
I was looking for a Haskell library with AES256 encryption/decryption capabilities and found quite a few.
The problem is that most of these seem abandoned, except cryptonite who again seems like the least popular library (the one with the least amount of downloads).
I was wondering if using a library that seems outdated could be a problem (should I worry about possible security flaws, etc.) or if I should simply go with the one that seems most popular?
