Generate a keyed hash value using the HMAC method
====Description====
string
hash_hmac (
string
$algorithm
,
string
$data
,
string
$key
)
This can be used for cryptography or just for checksum calculations.
====Parameter====
$algorithm: Name of selected hashing algorithm. Current algorithms supported are:
^ Parameter ^ Algorithm ^ Return Size (characters) |
