Frequently asked questions

Is SHA-256 reversible?

No. SHA-256 is a one-way cryptographic hash function — you cannot recover the original text from the hash.

Is this safe for hashing passwords?

For production password storage, use a dedicated password-hashing algorithm like bcrypt or Argon2 with salting on the server side, not a raw SHA-256 hash.
