Frequently asked questions
How long is a SHA-256 hash?
256 bits, shown as 64 hex characters. "abc" hashes to ba7816bf8f01cfea414140de5dae2223b00361a396177a9cb410ff61f20015ad.
How do I get the same hash on the command line?
macOS/Linux: shasum -a 256 file (or sha256sum file). Windows PowerShell: Get-FileHash file -Algorithm SHA256. For text, avoid echo adding a newline – use printf '%s' "text" | shasum -a 256.
Is SHA-256 good for passwords?
On its own, no – it is fast, so attackers can try billions of guesses per second. Use bcrypt, scrypt or Argon2 with a salt.
