The SHA256 online generator enables you to instantly generate a SHA256 (32-byte) hash of any string or input value, that can later be returned as a hexadecimal number of 64 digits.
SHA, abbreviation for Secure Hash Algorithm, is a cryptographic hashing algorithm used to test the integrity of a particular piece of data. SHA256 came after SHA1 to fight collision attacks, because it can generate a longer, harder to break hash.
The hashing is a method against decryption. This means that SHA256 is perfect for challenging hash authentication, finger-printing, password validation, digital signatures, uniquely identifying files, and checksums to detect accidental data corruption.
