Julia is an anonymous collective identity used to disclose information and
software aimed at protecting human rights on the network.
We focus our work showing the lack of technical requirements in the legislation
used to regulate Internet.
Julia is the pratical demonstration that the real-security, for information and
people, is where human rights are protected and not sacrificed and it won't ever
be achieved violating the own privacy.
Some security experts can demonstrate that the tools needed to counteract
pedophilia, terrorism and other generic and common crimes in the internet era, are:
techno control for mass interception, trusted computing, user profiling, censorship,
passwords extortion.
Julia will show you a different way to fight crimes operating throughtout open source
technology world.
The hackers universe has many ways to evading those privacy-threads, but it hasn't
any effect in the real-world; For this reason, Julia discloses such informations and
softwares for everyday users, not only for the "underground". This requires kinds of
communication and organization efforts more complex than those commonly required to
realize a privacy-project.
WHAT'S ELETTRA ?
Elettra is a software providing plausible deniable cryptography. It supports
a dynamic number of files and requires a password for each file.
when you need to decrypt a file, the password is able to find in the
encrypted archive the file related to it.
the security measure is in the protection of the number of files encrypted
in the archive, because the algorithm is thought to give a plausible ammission
that the data unencrypted is simple random data, and only one file is
encrypted in it.
for more information about elettra and julia, http://www.phrack.org the
issue #65 had an article about elettra.
WHERE ARE ELETTRA ?
Internet (https) https://www.winstonsmith.info/julia/elettra
Tor (http) http://5zaspldty2calvcq.onion/julia/elettra
anyway, https://www.winstonsmith.info can be not used for further projects,
the only way for verify our source is checking the public key signature.
REQUIREMENTS:
aptitude install cmake libmhash-dev libmcrypt-dev zlib1g-dev
or, get the libraries at:

HOW TO USE:
Elettra has five command: encrypt, decrypt, checkpass, help and example.
is executed with: elettra command [args]
we want to encrypt file /tmp/ls-manpage and /tmp/ps-manpage.
two file = two password we use "weirdness" and "foxnewsshower",
the order link:
ls-manpage (weirdness)
ps-manpage (foxnewsshower)
$ ./elettra encrypt /dev/shm/out 15% /tmp/ls-manpage::weirdness /tmp/ps-manpage::foxnewsshower
the size of our source file are:
$ ls -l /tmp/ls-manpage /tmp/ps-manpage
-rw-r--r-- 1 user user 7132 Jan 8 05:57 /tmp/ls-manpage
-rw-r--r-- 1 user user 36287 Jan 8 05:57 /tmp/ps-manpage
the command line specifies 15% of random paddinig. Required args for the
"encrypt" command, are the output file, the source files and the passwords
If passwords are not inserted via command line, they are prompted
interactively.
before the encryption gzip compression is used, the output file is:
$ ls -l /dev/shm/out
-rw-r--r-- 1 user user 42615 Jan 8 06:13 /dev/shm/out
now we have an encrypted archive. the elettra decryption routine takes a
password and, optionally, a destination directory:
$ ./elettra decrypt /dev/shm/out weirdness /dev/shm/
$ ls -l /dev/shm/
-rw-r--r-- 1 user user 7132 Jan 8 06:32 ls-manpage
-rw-r--r-- 1 user user 42615 Jan 8 06:13 out
if you want to check your passwords, use the command "checkpass":
./elettra checkpass actresss weirdness shoeless
password(s) combinations work ok, with password block of 2304 bytes, use it.
if checkpass or encrypt command receive a bad password sequence, notice
to the users.
HACKING:
Elettra actually randomize the creation time (ctime) of generated file.
If you want remove this feature, you need to recompile elettra
removing the #define at line 240 in elettra.c
