Cryptography & Hashing

Hashing primitives (MD5 / SHA-256 / SHA-512 / HMAC / CRC32) with hex and base64 encoding, base encoding (Base32 / Base58 / Base62 / Base64URL) for URL-safe ID transport, MIME-type detection from magic bytes (so an uploaded `.exe` renamed `.jpg` still surfaces), and safe-by-default YAML / shell-exec wrappers. The "I need to sign webhooks, hash passwords, or detect file types" layer.

0 projects and 39 packages carry this capability.
