Frequently asked questions

SHA-1 vs SHA-256?
SHA-1: 160-bit, insecure. SHA-256: 256-bit, currently secure.
Is SHA reversible?
No. SHA is one-way. Cannot restore original data from hash.
Is SHA-256 secure?
Yes. No practical attacks known. Widely used in blockchain and certificates.
When to use SHA-512?
For highest security requirements. SHA-256 is sufficient for most cases.
SHA for passwords?
Not recommended directly. Too fast for brute-force. Use Bcrypt or Argon2.
