The E-Keyed File Encryptor was designed and developed from the ground up with security at the forefront. Utilizing a Master Encryption Key, which is unique to your device, a Custom Device Linking System, and multiple advanced security features, you can rest assured that your data, or data you wish to share, is thoroughly protected.

Operating completely offline, the E-Keyed File Encryptor does not require internet access, only storage permission for encrypting or decrypting selected files and the camera permission to decrypt an encrypted QR-Code. This makes it an ideal tool for users who prioritize privacy and security.

The E-Keyed File Encryptor offers two encryption options: Encrypt File and Encrypt File with Password, both utilizing 256-bit AES encryption and Argon2.

• Encrypt File: Recommended for personal use, this option links the encrypted file to a Master Encryption Key unique to your device, which is generated on app startup if not already available. The Custom Device Linking System ensures that only your device can decrypt the files.

• Encrypt File with Password: Recommended for sharing files, this option does not use your Master Encryption Key or device information. Instead, it links the file to a password (16-128 characters) you set, along with a custom verification system.

The E-Keyed File Encryptor includes a feature aptly named "The E-Keyed Guard Dog," which continuously monitors for security, validity, integrity, and systems check failures, providing alerts as necessary and an "E-Keyed Security Hub" for showing not only a range of helpful information but also several checks and functions you can perform on both the app and any files generated with the E-Keyed File Encryptor.

Very regular updates are released to enhance security, functionality, stability, and the overall user experience, ensuring the application remains the top choice for file encryption.

Your data's security and your privacy are my top priorities. As such, the E-Keyed File Encryptor will never encrypt, decrypt, or modify your files without your explicit permission. Active support is provided for bug reports, questions, and feature requests, with a commitment to promptly respond and improve the app based on user feedback.

Important Notes: As the E-Keyed File Encryptor has been designed and developed for one sole purpose, to keep your data safe and secure at all costs, the Master Encryption Key is partially derived from your device hardware info, with added random data for extra security. Therefore, if you lose or change devices, uninstall the app, or clear your Secure Storage without first decrypting your encrypted files using the original device and that specific and unique Master Encryption Key used to encrypt them, your data can never be decrypted.

There are no "Backdoors" or "Skeleton Keys", so if you have an encrypted file and are in need of my help in decrypting it, even in the most dire of circumstances, it's impossible for me to help you. Only the user with their original device and unique Master Encryption Key used to encrypt it can decrypt the file.

Bonus Encryption Feature: The Custom One-Time Pad (OTP) encryption system was developed to provide the highest level of security for creating, sending, or sharing encrypted messages via text files or QR-Codes.

By redesigning the original method, you can now generate one OTP Key File and encrypt as many messages or QR-Codes as you like for a single recipient without compromising the messages or QR-Codes.

UI Notice: The user interface is designed for small to medium screens, such as phones and small tablets. Screenshots for an average-sized phone and a 7-inch tablet are provided for reference.
