    s2n-quic

    s2n-quic

    An implementation of the IETF QUIC protocol

    ...This library integrates with AWS’s s2n-tls or rustls for the TLS 1.3 handshake and leverages Rust’s memory and thread safety guarantees to deliver a robust implementation. It is built with configurability in mind—you can tune congestion control (like CUBIC), pacing, packet size discovery, and other advanced network behaviors. Extensive testing (unit, fuzz, interop) ensures protocol compliance and interoperability with other implementations. Because it is open-source under Apache 2.0, organizations can integrate it into services where low latency, multiple streams, or mobility (connection migration) matter.

    Novel Insight Inner Circle

    Novel Insight Inner Circle

    Graphical message and file encryption tool

    ...The software is developed in Java and requires 64bit Java JRE. The encryption uses AES-256 twice so it is harder to crack than the industry standard pure AES 256bit implementation (theoretical key size is 512 bit). The software writes encrypted data in ASCII text format which can be cut'n'pasted to messaging apps or to emails and back to Inner Circle when decrypting data. IMPORTANT: The software requires new OpenJDK 16 (Not Oracle's J2RE 1.8) to run. Install, for example, AdoptOpenJDK for Windows. NOTE: By using encryption twice the implementation is (in theory) vulnerable to Meet-In-The-Middle attack reducing key size to 256bit but the attack still requires 2^256 bytes of memory making it impossible in practice.

    SES Super-Encypherment Scrambler

    SES Super-Encypherment Scrambler

    SES brings back the uncrackable onetime pad, with a digital twist.

    ...SES is built on ISAAC, Bob Jenkins' unbroken CSPRNG, a fast and simple stream cipher placed in the Public Domain in 1996. SES now gives you the ability to efficiently cipher text of arbitrary length or files of any size or type. Use it with confidence. To achieve complete one-on-one privacy, SES traverses several levels en route to its output. The more words in your key-phrase, the more layers of encipherment SES applies. It is part Vigenere, part onetime pad, part cryptographic hash, not to mention the essential scrambler element, each component driven by ISAAC, with all key-derivation and stretching relying on Keccak in 512-bit configuration.
