Botan

| Vit | 92.14 |
Botan is a crypto library written in C++. It provides a variety of cryptographic algorithms, including common ones such as AES, MD5, SHA, HMAC, RSA, Diffie-Hellman, DSA, and ECDSA, as well as many others that are more obscure or specialized. It also offers SSL/TLS (client and server), X.509v3 certificates and CRLs, and PKCS #10 certificate requests. A message processing system that uses a filter/pipeline metaphor allows for many common cryptographic tasks to be completed with just a few lines of code. Assembly and SIMD optimizations for common CPUs offers speedups for critical algorithms like AES and SHA-1.

| Vit | 8.77 |
Libecc is a C++ elliptic curve cryptography library that supports fixed-size keys for maximum speed. The goal of this project is to become the first free Open Source library providing the means to generate safe elliptic curves, and to provide an important source of information for anyone with general interest in ECC.

|---|---|
| Vit | 7.86 |
Bit::Vector is a (stand-alone) C library and an object-oriented Perl module (with overloaded operators) which allows you to handle bit vectors, sets (of integers), "big integer arithmetic" (e.g. for cryptography), and boolean matrices (all of arbitrary size) very efficiently.

crank
| Pop | 130.49 |
|---|---|
| Vit | 2.90 |
Crank is a project to provide a GUI toolkit to facilitate (and where possible, automate) the breaking of classical (pen-and-paper) cryptosystems. Initial focus is on the cryptanalysis of monoalphabetic substitution ciphers.

alph
| Pop | 90.47 |
|---|---|
| Vit | 6.35 |
alph implements and analyzes historical and traditional ciphers and codes, such as polyalphabetic, substitutional, and mixed employing human-reconstructable algorithms. It provides a pipe filter interface in order to encrypt and decrypt block text to achieve transparency. The program is meant to be used in conjunction with external programs that transfer data, resulting in transparent encryption or decryption of information. The program can thus be used as a mail filter, IRC filter, IM filter, and so on.

ACL2
| Pop | 86.35 |
|---|---|
| Vit | 5.64 |
ACL2 is a mathematical logic, programming language, and mechanical theorem prover based on the applicative subset of Common Lisp. It is an "industrial-strength" version of the NQTHM or Boyer/Moore theorem prover, and has been used for the formal verification of commercial microprocessors, the Java Virtual Machine, interesting algorithms, and so forth.

General Purpose Hash Function Library
| Pop | 57.41 |
|---|---|
| Vit | 1.42 |
The General Purpose Hash Function Algorithm library contains implementations for a series of commonly used additive and rotative string hashing algorithms in the C++ programming language.

Virtual Ideal Functionality Framework
| Pop | 50.41 |
|---|---|
| Vit | 4.04 |
Virtual Ideal Functionality Framework is a framework for creating efficient and secure multi-party computations (SMPC). Players, who do not trust each other, participate in a joint computation based on their private inputs. The computation is done using a cryptographic protocol which allows them to obtain a correct answer without revealing their inputs. Operations supported include addition, multiplication, and comparison, all with Shamir secret shared outputs.

|---|---|
| Vit | 1.00 |
Tutorial Environment for Cryptographic Protocols (TECP) is a tutorial and visualization environment for public key cryptography. It is intended for students of cryptography courses and can be used to improve understanding of modular arithmetic-based public key algorithms, and for lecturers who want to add some life to boring blackboard-and-chalk presentations about the topic.

distributed.net clients
| Pop | 48.16 |
|---|---|
| Vit | 1.80 |
distributed.net is a loosely knit group of computer users from all of the world that is taking up challenges requiring lots of computing power (most notably the RC5, DES, and OGR cracking contests). It is simple to participate in the challenges by downloading and running their client software (which uses idle CPU time to complete its tasks).
