Overview

cryptiles is a package for general crypto utilities.

Affected versions of this package are vulnerable to Insecure Randomness. The randomDigits() method is supposed to return a cryptographically strong pseudo-random data string, but it was biased to certain digits. An attacker could be able to guess the created digits.
