Activation Key .NET Class Library
Represents the activation key used to protect your C# application.
A specific software-based key for a computer program C# source code. It certifies that the copy of the program is original. It is also called a license key, product key, product activation, software key and even a serial number. The key can be stored as a human readable text for easy transfering to the end user. Contains methods for generating the cryptography key based on the specified hardware and software binding. -

NutsDB
A simple, fast, embeddable, persistent key/value store written in Go
...Read-only transactions can read values for a given bucket and a given key or iterate over a set of key-value pairs. Read-write transactions can read, update and delete keys from the DB. NutsDB allows only one read-write transaction at a time but allows as many read-only transactions as you want at a time. Each transaction has a consistent view of the data as it existed when the transaction started. When a transaction fails, it will roll back, and revert all changes that occurred to the database during that transaction. -

Delaunator
Fast JavaScript library for Delaunay triangulation of 2D points
...What’s a half-edge? A triangle edge may be shared with another triangle. Instead of thinking about each edge A↔︎B, we will use two half-edges A→B and B→A. Having two half-edges is the key to everything this library provides. It will also be useful to have some helper functions to go from one half-edge to the next and previous half-edges in the same triangle. We can draw all the triangle edges without constructing the triangles themselves. -

Rubix ML
A high-level machine learning and deep learning library for PHP
...Our intuitive interface is quick to grasp while hiding alot of power and complexity. Write less code and iterate faster leaving the hard stuff to us. Rubix ML utilizes a versatile modular architecture that is defined by a few key abstractions and their types and interfaces. Train models in a fraction of the time by installing the optional Tensor extension powered by C. Learners such as neural networks will automatically get a performance boost. -

PetoronHash-System
PHASH | post-quantum XOF hashing algorithm | C++20
...This release delivers the first fully stable production implementation of the PetoronHash-System — a 1600-bit sponge-based hash function with domain separation, extendable output, and deterministic behavior. Key Features No external dependencies — pure C++20 implementation. Extendable Output (XOF) — supports arbitrary output length (256–8192+ bits). Post-quantum oriented design — ARX-based sponge resistant to Grover-type attacks. Context and salt separation — unique hashing domains for each use-case. Optimized performance — ~120–130 MB/s Comprehensive verification — verify_all.sh performs KAT tests, determinism checks, and performance validation. ... -

TextTeaser
TextTeaser is an automatic summarization algorithm
textteaser is an automatic text summarization algorithm implemented in Python. It extracts the most important sentences from an article to generate concise summaries that retain the core meaning of the original text. The algorithm uses features such as sentence length, keyword frequency, and position within the document to determine which sentences are most relevant. By combining these features with a simple scoring mechanism, it produces summaries that are both readable and informative.... -

XOR encrypt v2.0
Encrypt Your Text documents with XOR encryption
...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 -

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. ... -

textcrypter
textcrypter is an encryption tool using vigenere cipher algorithm
Textcrypter is an encryption tool using vigenere cipher algorithm. Vigenere use the same key/password to encrypt and decrypt a file (symmetric key cryptosystem). Result of the encryption process is a ciphertext in hexa number. -
