hash_hkdf - Generate a HKDF key derivation of a supplied key input
hash_hmac - Generate a keyed hash value using the HMAC method
hash_hmac_algos - Return a list of registered hashing algorithms suitable for hash_hmac
hash_hmac_file - Generate a keyed hash value using the HMAC method and the contents of a given file
hash_init - Initialize an incremental hashing context
hash_pbkdf2 - Generate a PBKDF2 key derivation of a supplied password
