    Naeon

    Naeon

    The safest way to store private data in untrusted (cloud) environments

    Naeon secures data in untrusted off-site storage through a layered approach: files are compressed, then AES-256 encrypted with a randomly generated 128-character passphrase yielding approximately 762 bits of entropy — far beyond the reach of both classical and quantum brute-force attacks. The ciphertext is obfuscated by prepending and appending random byte blocks, making the result unidentifiable as an encrypted file. The payload is then sharded into one private chunk — holding the...

    Advanced Onion Router
    ...Some of the improvements include UNICODE paths, support for HTTP and HTTPS proxy protocols on the same Socks4/Socks5 port with HTTP header filtering that generates fake identity-dependent headers every time the identity is changed (proxy chains are also supported), support for NTLM proxies, a User Interface that makes Tor's options and actions more accessible, local banlist for forbidden addresses, private identity isolation, a point-and-click process interceptor that can redirect connections from programs that don't support proxies, also giving them fake information about the local system and support for .onion addresses. Also, it can estimate AS paths for all circuits and prevent AS path intersections, it can restrict circuits to be built using only nodes from different countries, can change circuit lengths and more.

    lecithine

    FUSE File system powered by secret sharing scheme

    Lecithine is a FUSE (file system in user space) using a secret sharing scheme. You can use Lecithine as regular file system. When writing to disk, data will be devided into randomly chosen pieces (secret shares) and stored into different places. Upon reading, the shares are merged together such that in turn the plaintext results. From a cryptographers point of view, there is no symmetric or private key ever needed to produce a ciphertext.
