Optimised for 1920x1080 - Proudly mobile unfriendly

To download a ready-to-use version (v.1.3), visit the ChromaticEncryption repository of my GitHub account.
Version 1.3
13-Mar-2016
Improvements over the previous version:
  • Modifications in the encryption algorithm to ensure that no character will ever be misinterpreted.
    NOTE: the previous v. 1.2 might misinterpret some characters, but the chances of this occurring are very low.
  • Still stronger and more scalable/adaptable encryption algorithm.
Other versions:
1.0

1.2

WARNING - Unless expressly stated otherwise, there is no backwards compatibility among versions. When decrypting a file, make sure that you rely on the version used to encrypt it.

Text to encrypt:
  • Only PNG files are supported. The higher the quality/resolution the quicker the encrypting/decrypting process, but bigger files consume more resources (i.e., whole process slower).
  • Virtually any "normal" image should be fine. Examples of bad input images: the ones including just (shades or slight variations of) one colour or a few of them; black and white is a particularly problematic combination. Additionally, all the versions so far (up to v. 1.3) of the encryption algorithm tend to affect the appearance of artificially-altered images (e.g., including transparency) in a quite relevant way.
  • There is a maximum of 500 and 15 characters for text to encrypt and password respectively. All the characters are supported.
  • There is a 2 minute timeout. It is usually triggered by wrong inputs (e.g., bad image, not encrypted information or wrong password).
  • Under normal conditions, encrypting/decrypting shouldn't take longer than a few seconds.
  • No copy of the input information will remain in the server for longer than a few minutes.
  • This is the first version of the algorithm and also of this approach (i.e., encrypting information in images without affecting their appearance in a relevant way). That's why I will be happy to get some feedback about it.
