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. -

A slightly reduced strength bulk encryption. In exchange for the reduced strength, you get the ability to rsync the encrypted files, so that local changes in the plaintext file will result in (relatively) local changes to the cyphertext file.

The Safe C Library provides bound checking memory and string functions per ISO/IEC TR24731. These functions are alternative functions to the existing standard C library that promote safer, more secure programming. The ISO/IEC Programming languages — C spec, C11, now includes the bounded APIs in Appendix K, "Bounds-checking interfaces". This latest upload supports building static library, a shared library and a linux kernel module.

Vigenere Dictionary Attack
Vigenere brute force / dictionary cracking tool
This is a tool that uses a combination between a brute force and dictionary attack on a Vigenere cipher. At present, keys are generated using brute force (will soon try passwords generated from a dictionary first). Each key is then used to decode the encoded message input. The output is analysed and then put into a ranking table. Outputs will be ranked on a variety of factors (at present, only number of dictionary words in output are counted). For the future: Better key generation, trying combinations of dictionary words with numbers. If that fails, brute force will be used. For all attempts of the dictionary attack, only keys within the known key length range will be generated. Better ranking system and analysis of possible decoded messages. Note: The version currently released, I made in an evening! It is nowhere near ready for release but is a fun project to think about and I need more ideas for improvements mentioned above. Discuss possible solutions and ideas! -

XOR encrypt v2.0
Encrypt Your Text documents with XOR encryption
This software provides an easy graphical way to encrypt your text documents from source code , text files ,scripts even jpeg files .It is a enhanced version of my earlier project https://sourceforge.net/p/xorencrypt which used win32 GUI . This is a demonstration of working of XOR encryption which was used by Germans in World War II (http://en.wikipedia.org/wiki/Lorenz_cipher) . Besides from XOR'ing the message with password after every encryption the key changes pseudorandomly. The password you provide is hashed ( SHA256 ) and saved into the encrypted file to check if the password provided is correct.This algorithm has limitations in general more the numbers of relative characters in the password to plaintext more secure will be the encryption. XOR encrypt has a 3.5 of 5 editors rating from softpedia http://www.softpedia.com/get/Security/Encrypting/XOR-Encrypt.shtml -

CryptoSwift
Collection of standard and secure cryptographic algorithms
The master branch follows the latest currently released version of Swift. If you need an earlier version for an older version of Swift, you can specify its version in your Podfile or use the code on the branch for that version. Older branches are unsupported. Swift Package Manager uses debug configuration for debug Xcode build, that may result in significant (up to x10000) worse performance. Performance characteristic is different in Release build. XCFrameworks require Xcode 11 or later and they can be integrated similarly to how we’re used to integrating the .framework format. Embedded frameworks require a minimum deployment target of iOS 9 or macOS Sierra (10.12). CryptoSwift uses array of bytes aka Array<UInt8> as a base type for all operations. Every data may be converted to a stream of bytes. You will find convenience functions that accept String or Data, and it will be internally converted to the array of bytes. -
