Encrypt & Decrypt Text

De&EnCrypt is a lightweight utility for developers, students, security learners, and anyone who needs quick text conversion, hashing, encryption, or decryption on Android. The app is built as a practical tool: type or paste text, choose a transform, run the action, and copy the result. It is useful for debugging encoded payloads, checking hashes, converting text formats, experimenting with classic ciphers, or testing Java Cryptography Architecture cipher modes. Key features Base32 encode and decode Base64 encode and decode Hex encode and decode Binary encode and decode Octal encode and decode ASCII decimal conversion HTML entity conversion UTF-16 style escape conversion Morse code conversion Roman numeral conversion Vigenere cipher support SHA-256 and MD5 text hashing File hash verification for SHA-256 and MD5 Cipher support for algorithms such as AES, ARCFOUR, Blowfish, DES, DESede, and RC4 Configurable cipher mode, padding, key, IV, and input/output format Fast copy, paste, clear, and swap actions Designed for developer workflows Clean input and output panels Monospace text for easier reading System light/dark theme support Output remains easy to review while controls stay near the bottom File picker support for verifying file hashes No account required Privacy-focused core processing Most text operations are performed directly on your device. Text, keys, IV values, and selected file contents are not uploaded to a developer server by the core app. The app uses ads, so advertising partners may process advertising-related data as described in the privacy policy. Common use cases Decode Base64 API payloads Convert strings to Hex, Binary, Octal, or ASCII codes Generate SHA-256 or MD5 hashes Verify a downloaded file against a known hash Test AES/DES/Blowfish cipher settings Experiment with Vigenere, Morse, Roman numerals, and HTML entities Copy converted text into another tool or app Important notes This app is a general utility and learning tool. Some cipher mode and padding combinations depend on Android's available crypto providers and may not be supported on every device. If an operation fails, the app shows an error message in the output panel. De&EnCrypt does not replace a full password manager, key management system, or professional security audit tool. Always handle sensitive keys and data carefully.
