String result = DigestUtils.sha256Hex(password);SHA256 is a hashing function, not an encryption function. Secondly, since SHA256 is not an encryption function, it cannot be decrypted. ... In that case, SHA256 cannot be reversed because it's a one-way function.A hash function cannot be 'decrypted', but a rainbowtable
can be used to try and find a plaintext match. Still,
that doesn't guarentee a match.kamal12341234565String password = "123456";
