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
$ctx = hash_init('sha1');
hash_update($ctx, 'The quick brown fox jumped over the lazy dog.');
echo hash_final($ctx);
?>
