Frequently asked questions
Is it safe to hash passwords here?
The hashing runs locally, so your text never leaves the device. But for storing passwords use bcrypt or Argon2 — plain SHA/MD5 are too fast for password storage.
Which algorithm should I choose?
SHA-256 is the modern default. MD5 and SHA-1 are kept for legacy checksums and compatibility only.
Can I hash a file?
This page hashes text. For file checksums, encode the file with our Base64 tool or use your OS utilities (certutil, shasum).
