Usage

  1. Enter text in the input field
  2. SHA-256, SHA-384, SHA-512 hashes are generated automatically
  3. Copy generated hash for password, integrity check, or signature verification

When to use

Verifying password hash design, file checksum comparison, API signature verification.

FAQ

What is SHA-256?

Secure Hash Algorithm 256. One-way function producing 256-bit (64 hex char) hash. Same input → same hash.

Hash vs encryption?

Encryption is reversible. Hash is one-way. Use hash for passwords, encryption for secrecy.

Why hash passwords?

Plain text is risky if leaked. Hash is irreversible; verify by hashing input and comparing. Prefer bcrypt/Argon2 for passwords.

SHA-256 vs SHA-512?

Different output length: 256 vs 512 bits. Both secure; SHA-512 slightly stronger, longer output.
