HASH_HMAC_FILE(3) 1 HASH_HMAC_FILE(3)hash_hmac_file - Generate a keyed hash value using the HMAC method and the contents of a given fileSYNOPSIS
string hash_hmac_file (string $algo, string $filename, string $key, [bool $raw_output = false])
DESCRIPTION PARAMETERS
o $algo
- Name of selected hashing algorithm (i.e. "md5", "sha256", "haval160,4", etc..) See hash_algos(3) for a list of supported algo-
rithms.
o $filename
- URL describing location of file to be hashed; Supports fopen wrappers.
o $key
- Shared secret key used for generating the HMAC variant of the message digest.
o $raw_output
- When set to TRUE, outputs raw binary data. FALSE outputs lowercase hexits.
RETURN VALUES
Returns a string containing the calculated message digest as lowercase hexits unless $raw_output is set to true in which case the raw
binary representation of the message digest is returned.
EXAMPLES
Example #1
hash_hmac_file(3) example
<?php
/* Create a file to calculate hash of */
file_put_contents('example.txt', 'The quick brown fox jumped over the lazy dog.');
echo hash_hmac_file('md5', 'example.txt', 'secret');
?>
The above example will output:
