Phar->getSignature — Return MD5/SHA1 signature of a Phar archive
Returns the verification signature of a phar archive in a hexadecimal string.
Array with the opened archive's signature in "hash" key and "md5" or "sha1" in "hash_type". This signature is a hash calculated on the entire phar's contents, and may be used to verify the integrity of the archive. A valid signature is absolutely required of all phars if the phar.require_hash INI variable is set to true.
