Hash Generator
Computes every common digest from one paste or dropped file — MD5, SHA-1, SHA-256, SHA-384, SHA-512 and CRC32 — with hex or Base64 output, expected-digest compare, and bcrypt hashing plus verify at an adjustable cost factor.

Notes
- MD5 and SHA-1 are cryptographically broken; use them for checksums and cache keys, never for passwords or signatures.
- Plain hashes are the wrong tool for passwords no matter the algorithm — bcrypt's salt and cost factor exist precisely to slow attackers down.
- When a secret key is involved, use the HMAC Calculator instead — plain hashes cannot prove authenticity.
