Type or paste your text, and the tool generates MD5, SHA-1, SHA-256, SHA-384, and SHA-512 hashes all at once, live.
A one-way function that maps arbitrary data to a fixed-size digest. Changing one character produces a completely different hash.
SHA-256 or SHA-512 for security. MD5 and SHA-1 are broken for security use but fine for checksums.
No — hash functions are one-way. You cannot recover the input from the hash.
