Phar::getSignature — Return MD5/SHA1/SHA256/SHA512/OpenSSL 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,
SHA-1,
SHA-256, SHA-512, or OpenSSL
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 executable phar archives if the
phar.require_hash INI variable
is set to true.
If there is no signature, the function returns false.
