What is a hash function?
A cryptographic hash function converts any input text into a fixed-length string. The same input always produces the same hash, but even a small change creates a completely different result. Hashes are used to verify file integrity, store passwords, and detect duplicates.
SHA-256 vs SHA-512
SHA-256 produces a 64-character hex string and is the most widely used. SHA-512 produces a 128-character string and offers more security but is slower. SHA-1 is older and no longer recommended for security purposes.
