SHA-256 is a cryptographic hash function used to verify data integrity. It is used in password storage (with bcrypt/argon2), digital signatures, blockchain, and file checksum verification.
No. SHA-256 is a one-way function — you cannot reverse a hash back to the original text mathematically. Only brute-force or rainbow table attacks work for weak inputs.
A strong password is at least 16 characters, uses uppercase, lowercase, numbers, and symbols, and is unique per site. This generator creates cryptographically random passwords.
