This free app lets you easily encrypt and decrypt text using classic encryption methods, such as the Caesar cipher (shifting letters by a fixed number of positions), the Vigenère cipher (using a keyword for variable shifts), and the Vernam cipher (one-time pad with a random key for absolute security).
The interface is simple and user-friendly: paste text from the clipboard or type it manually, select the cipher type and key, and get the encrypted result, which you can instantly copy for use in messages, notes, or other apps.
Perfect for cryptography students, data-security enthusiasts, or just for fun. No in-app purchases — everything is completely free! Updates bring new ciphers and features.
