Password.File

If you need to send sensitive files (such as bank statements or a tax return) to someone over insecure channels (such as email), you can use Password.File to put the file(s) inside of a password-protected and AES-encrypted container and send the container file instead. Call the recipient and tell them the password you've chosen, and they would use Password.File to extract the original files from the container and save them to their own device.

This app can password-protect any file type, including DOCX,DOC,XLSX,XLS,PDF,PPT,MP3,MP4,etc. It uses strong AES encryption with 256 bit keys and hides file names of the encrypted files. Supports languages other than English.
