Android application that gets a request from a server and then encrypts the specified directory on the SD card. Also will display files and folders from the SD Card, and will allow you to encrypt/decrypt files from the app itself.
Client
- Client chooses folders to encrypt and sends over to the server
- Client does the encryption on the device after sending folders over to server
- Encrypted files are denoted with a ".encrypted" ending ( this can be changed later )
- Encryption is done by compressing the folder and then encrypting the zip. Decryption is done the same (decrypting and then unzipping).
- Client can also decrypt on the device. Just choose folders that are
Server
- Recieves folders from Client in string form.
- Gives Client acknowledgement that it has been recieved.
- Encryption does not get rid of the old files, i.e. unencrypted file and zipped
- Salt is the same for every user
- Server does not keep a record of the folders the user wants to keep encrypted.
- No web service to actually send a message to the device.
