AESCrypt

AESCrypt for iOS decrypts/previews files encrypted and saved in the cloud (Dropbox, Drive, Evernote, Email, etc). The files must be previously encrypted using the free encryption software at AESCrypt.com.
An in-app purchase/upgrade allows you to encrypt files/documents from other apps or pictures taken with the camera securely from inside AESCrypt for iOS. You can then share these encrypted files with your favorite cloud app.
AESCrypt.com is a free file encryption software available on several operating systems that uses the industry standard Advanced Encryption Standard (AES) to easily and securely encrypt files.
AESCrypt is the perfect solution for those who wish to backup information and store that data in a cloud-based storage service or any place where sensitive files might be accessible by someone else.
