Hash Generator
Generate SHA-1, SHA-256, SHA-512 hashes
What is a Hash Function?
A cryptographic hash function takes input data and produces a fixed-size string (hash). The same input always produces the same hash, but it is computationally infeasible to reverse.
SHA-1 vs SHA-256 vs SHA-512
SHA-256 and SHA-512 are part of the SHA-2 family and are considered secure. SHA-1 is deprecated for security use but still used for checksums. SHA-512 produces a longer hash and is slower but more secure.
