HASH_HMAC(3) 1 HASH_HMAC(3)hash_hmac - Generate a keyed hash value using the HMAC methodSYNOPSIS
string hash_hmac (string $algo, string $data, 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 $data
- Message to be hashed.
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. Returns FALSE when $algo is unknown.
EXAMPLES
Example #1
hash_hmac(3) example
<?php
echo hash_hmac('ripemd160', 'The quick brown fox jumped over the lazy dog.', 'secret');
?>
The above example will output:

HASH_FINAL(3) 1 HASH_FINAL(3)hash_final - Finalize an incremental hash and return resulting digestSYNOPSIS
string hash_final (resource $context, [bool $raw_output = false])
DESCRIPTION PARAMETERS
o $context
- Hashing context returned by hash_init(3).
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_final(3) example
<?php
$ctx = hash_init('sha1');

could be 5000+ lines
I have an algo and need a code to implement this:
1. Linecount = wc -l (should give 5000)
