How to use the Hash Generator
- Type or paste the text you want to hash into the input box.
- Click Generate Hashes to compute SHA-1, SHA-256, and SHA-512 simultaneously.
- Click Copy next to any algorithm to copy the hash to your clipboard.
What is a cryptographic hash?
A cryptographic hash function takes any input and produces a fixed-length, deterministic output called a digest. The same input always produces the same output, but even a single character change produces a completely different hash. Hashes are one-way — you cannot reverse a hash to recover the original text.
SHA-1 vs SHA-256 vs SHA-512
SHA-1 produces a 160-bit (40 hex chars) digest. It is no longer considered secure for cryptographic purposes and should not be used for digital signatures or certificates. SHA-256 and SHA-512 are part of the SHA-2 family and are currently secure for most applications. SHA-256 produces a 256-bit digest; SHA-512 produces 512 bits and is faster on 64-bit hardware.
