jsSHA implements the complete Secure Hash Standard (SHA) family (SHA-1, SHA-224/256/384/512, SHA3-224/256/384/512, SHAKE128/256, cSHAKE128/256, and KMAC128/256) with HMAC

/**
 * A JavaScript implementation of the SHA family of hashes - defined in FIPS PUB 180-4, FIPS PUB 202,
 * and SP 800-185 - as well as the corresponding HMAC implementation as defined in FIPS PUB 198-1.
