*** Testing hash_init(): error conditions ***

-- Testing hash_init() function with unknown algorithms --
hash_init(): Argument #1 ($algo) must be a valid hashing algorithm

-- Testing hash_init() function with HASH_HMAC and non-cryptographic algorithms --
hash_init(): Argument #1 ($algo) must be a cryptographic hashing algorithm if HMAC is requested

-- Testing hash_init() function with HASH_HMAC and no key --
hash_init(): Argument #3 ($key) cannot be empty when HMAC is requested

Deprecated: hash_init(): Passing null to parameter #3 ($key) of type string is deprecated in %s on line %d
hash_init(): Argument #3 ($key) cannot be empty when HMAC is requested
