FileCrypt is an opensource android application able to perform AES-128 bit encryption on image, audio and video files.

Steps to follow-
1. After Installation, provide the File and Media permission, otherwise app will crash at startup.
2. Encrypted file will be stored inside Documents folder with name FileCrypt_filename.
3. Decrypted file will be stored inside Documents folder with original filename.

Note- This app does not delete or remove the input file used for encryption or decryption; Instead, this app writes the file generated after encryption/decryption operation inside the Documents folder.
