Msg2File Pro

Msg2File Pro is a local file encryption tool that can encrypt text messages, images, or videos and append them to ordinary DOCX, XLSX, and PPTX Office files.

The resulting files can still be opened and viewed normally using common office software such as Microsoft Office and WPS; however, once opened with Msg2File Pro, an authorized recipient can decrypt and view the appended encrypted content.

Key Features:

Supports three common Office file formats: DOCX, XLSX, and PPTX

Supports encrypted text, images, and videos

Imports existing Office files and can quickly create new files using plaintext templates

Supports shared password encryption, saving passwords separately for different recipients

Supports X25519 public key encryption, eliminating the need for the sender to transmit the decryption password to the recipient

Supports exchanging public keys via QR code, and backing up and restoring encrypted private keys

Decrypted content can be saved to a local vault and managed by recipient

Supports biometric locking to protect local content in the app and vault

Supports file integrity verification to help identify damaged or modified encrypted files

Files can be shared via WeChat, QQ, email, cloud storage, and other common methods.

Privacy and Security:
Msg2File Pro's file processing, encryption, and decryption operations are all performed locally on the device. Passwords and private keys are stored in the device's secure storage area; the app will not actively upload your plaintext content, passwords, or private keys.

Shared password encryption is free to use. Some advanced features, such as X25519 public key encryption, require unlocking Msg2File Pro Premium.

Please keep your password and private key safe. If you forget your password or lose your private key, the encrypted content will be unrecoverable.
