Can SHA-256 be reversed?
No. Hashes are one-way—you cannot recover the original from the digest. Weak passwords may still be guessed via dictionaries.
SHA256 Generator
DevTools SHA256 Generator computes SHA-256 digests from input text locally in your browser—for checksums, signing prep, and integrity checks.

About this tool
SHA-256 is a standard cryptographic hash producing a fixed 256-bit digest. Identical input always yields the same hash—useful for dedup, verification, and pre-signing.
How to use
- Enter text to hash.
- View the hash generated in real time.
- Copy hex or Base64 output.
FAQ
Should I store passwords with SHA-256?
No. Use slow password hashes such as Bcrypt, Argon2, or scrypt with per-user salt.
Is hashing done locally?
Yes. SHA-256 runs in your browser via the Web Crypto API.
Is this tool free?
Yes. No sign-up required.
