Zend\Validator\File\Sha1 allows you to validate if a given file’s hashed contents matches the supplied sha1 hash(es). It is subclassed from the Hash validator to provide a convenient validator that only supports the sha1 algorithm.


This validator requires the Hash extension from PHP with the sha1 algorithm.

Supported Options

The following set of options are supported:

  • hash (string)

    Hash to test the file against.

Usage Examples

// Does file have the given hash?
$validator = new \Zend\Validator\File\Sha1('3b3652f336522365223');

// Or, check file against multiple hashes
$validator = new \Zend\Validator\File\Sha1(array(
    '3b3652f336522365223', 'eb3365f3365ddc65365'

// Perform validation with file path
if ($validator->isValid('./myfile.txt')) {
    // file is valid
