Frequently asked questions
Is SHA-256 secure?
Yes — no practical collisions or preimage attacks are known. It is the standard choice for integrity.
Why is it called 256?
The digest is 256 bits long; SHA-2 also defines 224, 384, and 512-bit variants.
Can I use it for passwords?
Not alone — use a password-specific KDF (bcrypt, scrypt, Argon2) with salts instead.
