Generate SHA-1, SHA-256, SHA-384, and SHA-512 hashes simultaneously using the native Web Crypto API. Output as hex or base64. All hashing happens locally.

————Security note
SHA-1 is broken for collision resistance — use SHA-256 or stronger for security-sensitive work. For password storage, never use any plain SHA hash; use a slow KDF like bcrypt, scrypt, or Argon2.
