shadowsocks-libev
Bug-fix-only libev port of shadowsocks
Shadowsocks-libev is a lightweight secured SOCKS5 proxy for embedded devices and low-end boxes. Shadowsocks-libev is written in pure C and depends on libev. It's designed to be a lightweight implementation of shadowsocks protocol, in order to keep the resource usage as low as possible. Snap is the recommended way to install the latest binaries. You can build shadowsocks-libev and all its dependencies by script. The latest shadowsocks-libev has provided a redir mode. You can configure your Linux-based box or router to proxy all TCP traffic transparently, which is handy if you use an OpenWRT-powered router. Although shadowsocks-libev can handle thousands of concurrent connections nicely, we still recommend setting up your server's firewall rules to limit connections from each user. We strongly encourage you to install shadowsocks-libev from jessie-backports-sloppy. -

xxHash
Extremely fast non-cryptographic hash algorithm
xxHash is an extremely fast non-cryptographic hash algorithm, working at RAM speed limit. It is proposed in four flavors (XXH32, XXH64, XXH3_64bits and XXH3_128bits). The latest variant, XXH3, offers improved performance across the board, especially on small data. It successfully completes the SMHasher test suite which evaluates collision, dispersion and randomness qualities of hash functions. Code is highly portable, and hashes are identical across all platforms (little / big endian). Performance on large data is only one part of the picture. Hashing is also very useful in constructions like hash tables and bloom filters. In these use cases, it's frequent to hash a lot of small data (starting at a few bytes). Algorithm's performance can be very different for such scenarios, since parts of the algorithm, such as initialization or finalization, become fixed cost. The impact of branch misprediction also becomes much more present. -

PureBasic Shamir Secret Sharing
Open-source PureBasic implementation of the Shamir Secret Sharing
PureBasic Shamir Secret Sharing is an open-source, self-contained and educational implementation of the Shamir Secret Sharing Scheme, written entirely in PureBasic. Shamir Secret Sharing is a cryptographic method that splits a secret into multiple parts (shares), such that any combination of at least T shares can reconstruct the original secret, while any number of shares fewer than T reveals no usable information. This implementation operates over the finite field GF(257), allowing correct handling of all byte values (0–255) without loss, making it compatible with any type of string or binary-compatible data. Main Features Complete implementation of Shamir Secret Sharing Arithmetic over GF(257) Compatible with all character strings Robust Lagrange interpolation Safe modular inverse computation Shares encoded in hexadecimal (3 characters per byte) Clear, well-commented source code ⚠️ Disclaimer This project is intended for educational and demonstration -

JCryptor
JCryptor is an encrypting tool based on the Caesar-cipher.
JCryptor uses the Caesar-cipher to encrypt keystrokes on-the-fly. It can also be used to decrypt an encrypted text easily. Caesar-cipher is a simple encryption algorithm, developed by Julius Caesar, to encrypt his correspondence with Cicero in the ancient world. Therefore it uses a simple character substitution method to replace a given character by another. A keyshift of thirteen is called ROT13. ROT13 can be decrypted by encrypting it again with ROT13. Even today this simple method is used by authorities to protect documents from unintentional reading. --UPDATE-- [25.01.14] Release 1.0 (final) -- Bugfixes [05.05.12] Release 0.2 -- implements polyalphabeticel substitution -

FinalCrypt
FinalCrypt - Unbreakable One-Time Pad Encryption
Why FinalCrypt? 1. Most people choose Disk-Encryption as it's easier to unlock a whole drive, but Big-Brother or Malware can then also read all your files. Only use File-Encryption! 2. Most software uses recently broken AES encryption. 3. Soon The Shor's algorithm will instantly break all assymmetric encryption with Quantum Computers. 4. FinalCrypt uses Symmetric One Time Pad Encryption, which is the most unbreakable encryption there is. 5. FinalCrypt is the only "One Time Pad", OpenSource, Cross-Platform, (Bulk) File Encryption Software available. -

file digest
A command-line utility for calculating and verifying file checksums.
Digest is a command-line utility which can be used to calculate and verify checksums of any files, similar to md5sum or RHash, but using modern hash algorithms. Supported algorithms: BLAKE, BLAKE2, Grøstl, JH, Kupyna, MD5, SHA-1, SHA-2, SHA-3, Skein, SM3, Streebog, Whirlpool. Usage: digest [-c] <algorithm> <filename(s)> For example, if you want to calculate the checksums using skein512/256 algorithm, use this command: digest skein512/256 * > checksums.skein To verify the checksums: digest -c skein512/256 checksums.skein You can get a full list of supported algorithms and test the performance of different algorithms on your PC using the command: digest test <iterations> <filename> This will calculate hash sum of <filename> multiple times (number of times is specified by <iterations>) and output the results with precise timings. Note: if you have a 64-bit operating system, use 64-bit binary of the utility, because it is significantly faster for large files. -
