AESLocker: File Encryption

Secure your files with AES-256 encryption — completely offline and free to use. AESLocker encrypts and decrypts your files directly on your device using AES-256 encryption. No internet connection is required for encryption or decryption — your files and passwords stay on your device. 🔒 AES-256 FILE ENCRYPTION Encrypt your files locally using AES-256 encryption with a password of your choice. Decryption is performed locally on your device as well. Key material is derived using PBKDF2-SHA512 with 600,000 iterations, with separate key material used for encryption and integrity protection. 🔐 INTEGRITY VERIFICATION AESLocker doesn't simply attempt to decrypt a file and hope the password was correct. Before decryption, AESLocker verifies the file's HMAC-SHA256 integrity tag. If verification fails, the file is not decrypted. This helps detect an incorrect password as well as file corruption or tampering. The same integrity verification is also performed by the AESLocker Recovery Kit. 🛡️ RECOVERY KIT AESLocker includes a Recovery Kit that lets you decrypt your encrypted files independently of the Android app. The kit contains a recovery script and complete instructions. It uses OpenSSL 3.0+ and runs locally on a computer or on Android through a terminal environment such as Termux, providing an independent way to access your encrypted files. The Recovery Kit is designed to be saved somewhere safe and independently of the app — useful for long-term access to your encrypted files. 🌐 CROSS-PLATFORM RECOVERY Your encrypted files don't have to remain locked to your Android device. With the Recovery Kit and OpenSSL 3.0+, you can decrypt AESLocker files on macOS, Linux, Windows through WSL or Git Bash, or directly on Android through a terminal app. The recovery process is performed locally, without uploading your files anywhere. 📴 100% OFFLINE All encryption and decryption performed by AESLocker happens locally on your device. Your files and passwords are never uploaded or transmitted by the app. 🔑 PASSWORD STRENGTH INDICATOR A password strength indicator provides real-time feedback to help you choose a stronger password before encrypting your files. 📦 KEEP YOUR RECOVERY KIT SAFE Because AESLocker uses password-based encryption, your password is essential for decrypting your files. Keep your password safe, and store the Recovery Kit somewhere independent of the app. AESLocker cannot recover a forgotten password. 🌍 42 LANGUAGES SUPPORTED AESLocker is available in 42 languages, including English, Español, Français, Deutsch, हिन्दी, العربية, 日本語, 한국어, 中文 (简体), and many more. 💰 FREE & AD-SUPPORTED AESLocker is free to use and supported by ads.
