AES-GCM, CBC, CTR, and ECB
Start the core Cipher workflow without leaving the MachKit toolbox.
Text & Data
Local AES, ChaCha, RSA, and SM crypto for Mac.
Cipher keeps cryptography local. Use AES and ChaCha modes, RSA, DES/3DES, and SM2/SM4—without uploading secrets to a website.
ChaCha20 / XChaCha20-Poly1305, RSA-OAEP / PKCS1, SM2/SM4
Keep the working input and generated result on the Mac.
DES / 3DES
Copy or continue with the result from the same consistent utility window.

Keep sensitive working data out of online converters
MachKit runs this utility as bundled local content. It does not require an account, analytics service, remote script, or cloud storage for the tool input.
- Bundled with the native Mac app
- No analytics or advertising
- No upload required for local transformations
Use one utility without installing another standalone app
Cipher shares MachKit’s searchable tool catalog, light and dark appearance, localization, clipboard feedback, and configurable global shortcuts.
- Part of the Text & Data category
- Searchable from the MachKit tools workspace
- Available through an optional global shortcut
FAQ
FAQ
Does Cipher send my keys or plaintext online?
No. Encryption and decryption run locally in MachKit. Nothing is uploaded for the Cipher workflow.
Which algorithms are included?
AES-GCM/CBC/CTR/ECB, ChaCha20/XChaCha20-Poly1305, RSA-OAEP/PKCS1, DES/3DES, and SM2/SM4.
