🔐 Base64 Hashing

A bundle of Base64, MD5, SHA family, AES, URL, HTML, hex, binary, CRC32, Caesar, and Morse tools. Everything runs locally in your browser.

🔒 Privacy: all computation happens locally in your browser. Text is never uploaded to any server.

📦 Base64 encode/decode

#️⃣ MD5 hash

Deprecated - do not use for security

MD5 has known collisions. Use it only for non-security file checksums or legacy system interop.

🔐 SHA family hash

SHA-1 is no longer recommended for security; prefer SHA-256 or SHA-512.

🛡️ AES encrypt/decrypt

Keep your key safe

Don't process sensitive data on a shared device. Key length and mode affect security; this tool is for light use only.
