EncryptPic is a fun and interesting way to securely store and share private information and pictures. The private text and picture is encrypted and hidden inside a separate unimportant visible image, allowing it to be not only securely encrypted with password protection, but also hidden in plain sight. On the surface, the otherwise innocuous image will blend in with any other inconsequential images. Nobody know the secret information is securely encrypted with optional password protection and hidden inside the image. This means if someone intercepts or has access to the public image, they will not have knowledge of or access to the additional secret information and embedded image. EncryptPic images can be stored on your phone in the application library, sent by SMS or Email messaging and stored anywhere else that they remain in full unaltered original format (for example on a computer hard drive, photo storage web sites, etc.). It is important to validate that any storage location does not alter the images and will store and return the unaltered original image in its full resolution. Any altering of the image from its original format can render the encrypted information inaccessible. For example, storing in the iPhone photo library will alter the image and render the encrypted information inaccessible. Always test any new storage method to make sure decryption is not affected before relying on that storage method. We cannot assist with repairing any corrupted altered or corrupted files.
