Use of a Broken or Risky Cryptographic Algorithm


Severity High
Score 9.1/10


CryptoES is a cryptography algorithms library compatible with ES6 and TypeScript. In versions prior to 2.1.0, CryptoES PBKDF2 is 1,000 times weaker than originally specified in 1993, and at least 1,300,000 times weaker than the current industry standard. This is because it both defaults to SHA1, a cryptographic hash algorithm considered insecure since at least 2005, and defaults to one single iteration, a 'strength' or 'difficulty' value specified at 1,000 when specified in 1993. PBKDF2 relies on the iteration count as a countermeasure to preimage and collision attacks. If used to protect passwords, the impact is high. If used to generate signatures, the impact is high. As a workaround, configure CryptoES to use SHA256 with at least 250,000 iterations.
