In a word, Renzhi Safe is an encrypted virtual safe, or an encrypted virtual disk, or an encrypted virtual volume, or an encrypted virtual data storage device.
For a longer description, Renzhi Safe is an Android application for establishing and maintaining an encrypt-on-the-fly safe (or volume, or data storage device). Data are automatically encrypted before they are saved, and decrypted after they are read, without any user intervention. No data stored in an encrypted safe can be read without first opening the safe with the correct password. The safe contains an entire file system, which is encrypted (e.g., file names, folder names, contents of files, free space, any other information).
Files can be copied to and from an opened safe just like they are copied to and from any normal folder. You can also perform drag-and-drop operations. As you read or copy a file from the safe, it is automatically decrypted. Similarly, as you move or copy a file to a safe, it is automatically encrypted on-the-fly.
Suppose you keep a secret photo inside a safe. After the safe is opened with the correct password, you can see the photo file, and view it with any photo viewer application that you have installed on your Android device. Once you are done viewing it, you can close the safe (i.e. lock it).
