GOOD TO KNOW

Frequently Asked Questions

Can SHA-256 hashes be reversed to the original text?

SHA-256 is a one-way hash function, not reversible encryption.

Why does a tiny input change produce a different hash?

SHA-256 is designed so small changes in input usually cause substantially different digests.

Can I use ordinary SHA-256 to store account passwords?

No. Password storage needs a dedicated password-hashing algorithm such as Argon2id, with appropriate configuration.

Is the SHA-256 result the same length for every input?

Yes. SHA-256 produces a 256-bit digest, usually shown as 64 hexadecimal characters.
