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.

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.
