The Squirrel Project

Most program features are available in free version: Squirrel Lite. What I am trying to sell is plausible deniability. Basic steganography is free.

RandomX algorithm distributes message in such a way, which makes it impossible to extract the message without the right password, but also makes it very difficult if not impossible to even detect the very existence of the message itself. Picture is just a little bit noisy, when we look at the covert image (7th bit), but even that is impossible to determine for sure without comparing it to an original carrier image.

Password settings, when edited and agreed between parties allow for full plausible deniability while negotiating passwords over an insecure media such as phone or Skype.
This is why these two features are not free, but available only in full version of Squirrel for a small fee of £7.

However, plausible deniability during covert communication is not something that can be sold. Achieving it mostly depends on the behaviour of users, whether they behave naturally during conversation or not, whether they accidentally expose some details during conversation or not. There is a lot of psychology involved and I will be analysing the problem from that angle as well.

There will be link to a secure PayPal site and initially all purchases will be processed manually, so please allow some time for processing. If there is enough purchase requests or if processing them becomes too much of a burden I will automate it.

In the meantime, if you really need full version of Squirrel now please send me an email to:

By making some money I will be able to allocate more time for development of Squirrel and implement more features.
