hash — Generate a hash value (message digest)
$algo,$data,$binary = false,$options = []
algoName of selected hashing algorithm (i.e. "md5", "sha256", "haval160,4", etc..). For a list of supported algorithms see hash_algos().
dataMessage to be hashed.
binary
When set to true, outputs raw binary data.
false outputs lowercase hexits.
optionsAn array of options for the various hashing algorithms. Currently, only the "seed" parameter is supported by the MurmurHash variants.
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.
| Version | Description |
|---|---|
| 8.1.0 | The options parameter has been added. |

hash() now throws a ValueError exception
if algo is unknown; previously, false was returned instead.
