Which hash should you use?

SHA-256 is today's workhorse — file integrity checks, API signatures, blockchain, certificate fingerprints. SHA-512 is its bigger sibling for extra margin. MD5 and SHA-1 are cryptographically broken for security purposes, but still everywhere as checksums, cache keys and legacy database fields — that's why this tool includes them. One important note: plain hashes are not the right way to store passwords — password storage needs a slow, salted algorithm like bcrypt.

FAQ

Can a hash be reversed back to the text?
No — hashing is one-way. But identical input always produces the identical hash, so short common strings can be guessed via lookup tables. Never treat a hash of a secret as encryption.
Why does the same text always give the same hash?
That's the point — hashes act as fingerprints. If even one character changes, the hash changes completely (the avalanche effect).
Does it handle emoji and non-English text?
Yes — text is hashed as UTF-8 bytes, matching what PHP, Python and other server languages produce.
