XText vs Crypto

XText is a secure text encryption and decryption app.Powered by high-strength AES encryption, it ensures your messages are unreadable, hard to spread, and extremely difficult to leak. XText supports decrypting cipher texts from XTexter. These cipher texts use a platform-wide shared key. Choose the right cipher for different scenarios: 1. Universal Cipher Prevents automatic parsing by messaging apps. Can be decrypted by all XText apps. 2. Custom Cipher Share information only with people who own the same secret key. Ensures that only designated recipients can read the content. 3. Client-to-Client Cipher Establishes an exclusive encrypted channel between you and the recipient. Only both parties can decrypt; no third party can access the content. 4. Burn-After-Reading Cipher Even with the same key, the message can only be decrypted once. It becomes invalid immediately after reading. Key Features: - Real-time encryption: The same text produces a different result every time, greatly improving security. - Generate and scan encrypted QR codes for easier sharing. - Biometric unlock support (Face ID / Touch ID) to protect app access. - Fast sharing: easily copy cipher text into any app. We firmly believe that truly secure data must keep transmission and encryption completely separate. Instant messaging apps that integrate encryption with communication are fundamentally insecure. XText Pro supports fully offline text encryption and decryption.

Dive into cryptography with Crypto. Use Caesar and Vigenère ciphers and encrypt and decrypt messages. CRYPTO Crypto allows you to encrypt and decrypt messages using Caesar and Vigenère ciphers. Create a message, select a key or a keyword, and then send the encrypted message to your friends. Similarly can you decrypt encrypted messages. CIPHERS In both Caesar and Vigenère ciphers, each letter is substituted with another, which makes them substitution ciphers. Only those who know the secret key are able to decrypt messages, though it is possible to decrypt an encrypted message without knowing the key by using brute force. CAESAR CIPHER In the case of Caesar’s cipher, we use a secret integral key (k). This secret key is used to rotate (i.e. shift) each letter by k places, wrapping A to Z and a to z as needed. For example, if we use the key of 1 to encrypt “Hello world!”, we will get “Ifmmp xpsme!” To decrypt this message, shift the letters backward. VIGENÈRE CIPHER Vigenère cipher improves upon Caesar cipher by shifting letters using different keys. This sequence of keys is known as a keyword. Each letter in the keyword represents by how far the corresponding letter in the original message will be shifted (A and a represent 0, B and b represent 1, Z and z represent 25). If we encrypt “Hello world!” with the keyword “Squirrel”, we will get “Zuftf nscdt!”
