Audited & minimal 0-dependency JS implementation of SHA, RIPEMD, BLAKE, HMAC, HKDF, PBKDF & Scrypt

/**
 * SHA2-256 a.k.a. sha256. In JS, it is the fastest hash, even faster than Blake3.
 *
 * To break sha256 using birthday attack, attackers need to try 2^128 hashes.
 * BTC network is doing 2^70 hashes/sec (2^95 hashes/year) as per 2025.
 *
 * Check out [FIPS 180-4](https://nvlpubs.nist.gov/nistpubs/FIPS/NIST.FIPS.180-4.pdf).
