Name of selected hashing algorithm (i.e. "md5", "sha256", "haval160,4", etc..) See hash_hmac_algos for a list of supported algorithms.
URL describing location of file to be hashed; Supports fopen wrappers.
Shared secret key used for generating the HMAC variant of the message digest.
When set to true, outputs raw binary data. false outputs lowercase hexits.
Returns a string containing the calculated message digest as lowercase hexits unless binary is set to true in which case the raw binary representation of the message digest is returned. Returns false when algo is unknown or is a non-cryptographic hash function, or if the file filename cannot be read.
|7.2.0||Usage of non-cryptographic hash functions (adler32, crc32, crc32b, fnv132, fnv1a32, fnv164, fnv1a64, joaat) was disabled.|
