I've just released version 0.1.3 of my Stes program, which is
used to automate making archive files, typically for open
source projects.
Stes is what can be called a Steganographic Encryption
System (hence the name), because it encrypts data in a file
while hiding whether other data is hidden in the same file.
More precisely, if you have a ciphertext file, cipher_file,
produced by Stes, and you know that decrypting cipher_file
with key key_1 produces a particular plaintext file
plainfile_1, then you cannot in general tell whether there
exist other decryption keys which will decrypt that
cipher_file to different plaintexts.
Not only do you not know whether such keys exist, you also
don't know how many such keys there are. Even if you know all
the keys, there is no way of demonstrating that no other such
keys exist.
This may be useful in applications where plausible deniability
is desired.
Stes can be downloaded from my website; the announcement is
