String.hash
hash()
Description
Apply one-way hash encryption to the string, using the SHA-256 algorithm.
A hashed string can not be decrypted back to its plaintext.
It will always be 64 characters long, regardless of the input length.
The hash will always be the same for a given input string, making it suitable for message digests or other fingerprinting.
SecurityDo NOT use this method for passwords. Use
toPassword() for stronger encryption instead.

$fileHash = fileContent.hash();
if $fileHash != $correctHash {
// File content has been changed
