PetoronHash2 (PH2) is a standalone ARX-based sponge construction that combines: A 4096-bit internal permutation core A sponge/duplex architecture with explicit capacity separation An extendable-output function (XOF) Memory-hard (HARD) and burn (BURN) modes A structured tagged absorb scheme A parameterized architecture suitable for hashing, KDF, and stress-oriented derivation PH2 is designed as a wide-state cryptographic primitive with explicit domain separation and configurable output length. https://github.com/01alekseev/PetoronHash2 Petoron | Ivan Alekseev | MIT license

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. ...

LDWM: Hash-Based Signatures (draft-mcgrew-hash-sigs-02), PHP implementation of IETF pqcrypto algorithm specification

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.

SecureQEMU is an open source emulation-based software protection scheme providing protection from reverse code engineering (RCE) and software exploitation using encrypted code execution and page-granularity code signing.

...The encrypted text can be copy/pasted into any text-handling application (e.g. email) instead of plain text. Convenience buttons are provided for clipboard operations. AESTextCrypt uses AES-256 bit encryption which is the strongest available encryption scheme. It also employs bcrypt, which implements key-stretching and an adaptive key setup phase, the complexity (number of rounds) of which is automatically set to match the processing power of the encrypting computer. This makes it highly resistant to dictionary attack. AESTextCrypt is written in Java, so can be run on all desktop platforms - Windows, Mac and Linux.

Shamir's Secret Sharing Scheme

Visual Cryptography is a graphical form of information concealing. In a 2-out-of-2 Visual Cryptography Scheme a dealer will "split" a secret image into two shares, print the shares onto separate transparencies and hand them to the participants to the scheme. If the two participants come together, they'll be able to reveal the secret image without a computer, perfectly superimposing the transparencies they own. Analyzing a single share, no one will be able to obtain any information considering the secret image no matter the computing or the analyzing power. ...

Java implementation of Shamir's Secret Sharing algorithm as described in Applied Cryptography [as LaGrange Interpolating Polynomial Scheme].

EasyVote is a new easy to use, secure and transparent cryptographic online voting scheme for small elections (up to 500 voters). The project contains the PHP files necessary to set up the server as well as the management tools.

MirandaFile is an encoding scheme unlike any other. It is, as far as I know, entirely unique.

LightCrypto is C cryptography library. It contains Big Number Library, basic crypto algorithms (3DES, DSA, RSA, ECDSA, etc), Internet Voting Scheme, and many more. Current librarie's binary is less than 1MB and it can even be smaller by user config.

Real-Time Proactive Secret Sharing Library for RTAI is an implementation of the Shamir's secret sharing scheme and Herzberg's proactive secret sharing algorithm. The library uses a port of GNU GMP in order to make multiple precision arithmetic operatio

CryptoGnome is an attempt to reinvent the wheel without reinventing the wheel. The final goal is an open source VCS similiar to ClearCase. There will be a major milestone at the CVS/PRCS level of functionality.

...A secret key is used to encrypt a session key, create a digital signature and to certify public keys. The system uses symetric encryption algorithm with a session key to encrypt messages. Shoup’s threshold signature scheme has been used for cooperative signing and also for cooperative decryption.
