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.
