PhotoCrypt is a utility to allow people to easily send and receive encrypted 'secret messages' between their friends.

The 'secret message' is actually embedded into the pixels of your photo. (This is called steganography - the practice of concealing messages or information within other non-secret text or data.)

Anyone viewing the encrypted photograph will never ever know that it contains a 'secret message' as it looks exactly like the original.

The encrypted photo can then be sent to friends via email.

Upon receiving the email with the attached encrypted photo, they then would download it to their phone/tablet, and then run it through this app to be decoded.

PhotoCrypt uses advanced encryption and cipher algorithms to embed your secret message within a photo. You can be assured that anyone who does not know the correct password and the corresponding secure key will not be able to decode the message.

The chances of brute forcing the correct passwords etc are in the order of 1 in 10 to the power of 80 or so if you use the build in random password generators. Considering that 1 billion (1,000,000,000) is 1 in 10 to the power of 9 and 1 trillion (1,000,000,000,000) is 1 in 10 to the power of 12, the chances of decoding any message randomly is extremely small.

PhotoCrypt is a real and viable alternative to other encryption software. It is certainly less 'suspicious' as your basic email message will not be coded and no-one would suspect the 'real' message to be hidden within the attached photograph.

It is ideal for storing sensitive information such as passwords, bank account information, basically anything that needs to be kept hidden and secure.

PhotoCrypt can store a number of phrases which contain a complex password and secure key.

For example, your email might say something like...

"Hello John, how's it going? I'm just back from holiday. Aren't you jealous.... just look at my photo attached of me enjoying my cocktail drink. I will talk to you soon!"

The phrase 'enjoying my cocktail drink' could be the phrase which was used to encrypt the photo with the secret message. If this 'phrase' is detected within PhotoCrypt, it would automatically select the correct password and secure key for decoding the attached photo in your email.

If you have the correct decode 'phrase' for the photo, you will be able to view your secret message with ease!

It is important to note that your encrypted photo will be a .png file format. PhotoCrypt will NOT be able to decode any photo which has been converted from the original encrypted .png format into a .jpg format. A number of websites including Facebook automatically convert any uploaded photo to a .jpg format.

PhotoCrypt was designed and released as a tool to demonstrate encryption techniques and should be used for educational purposes only.
