A cryptographically verifiable code review system for the cargo (Rust) package manager. cargo-crev is an implementation of Crev as a command-line tool integrated with cargo. This tool helps Rust users evaluate the quality and trustworthiness of their package dependencies. Crev is a language and ecosystem agnostic, distributed code review system. Use reviews produced by other users. Increase the trustworthiness of your own code. Build a web of trust of other reputable users to help verify the code you use. Static binaries are available from the releases page. Crev is a system for verifying the security and reliability of dependencies based on collaborative code reviews. Crev users review the source code of packages/libraries/crates and share their findings with others. Crev then uses Web of Trust to select trusted reviews and judge the reputation of projects' dependencies.

Advanced Onion Router is a portable client for the OR network and is intended to be an improved alternative for Tor+Vidalia+Privoxy bundle for Windows users. Some of the improvements include UNICODE paths, support for HTTP and HTTPS proxy protocols on the same Socks4/Socks5 port with HTTP header filtering that generates fake identity-dependent headers every time the identity is changed (proxy chains are also supported), support for NTLM proxies, a User Interface that makes Tor's options and actions more accessible, local banlist for forbidden addresses, private identity isolation, a point-and-click process interceptor that can redirect connections from programs that don't support proxies, also giving them fake information about the local system and support for .onion addresses. Also, it can estimate AS paths for all circuits and prevent AS path intersections, it can restrict circuits to be built using only nodes from different countries, can change circuit lengths and more.

AirSnort is a wireless LAN (WLAN) tool which cracks encryption keys on 802.11b WEP networks. AirSnort operates by passively monitoring transmissions, computing the encryption key when enough packets have been gathered.

KeyStore Explorer is a free GUI replacement for the Java command-line utilities keytool and jarsigner.

Shadowsocks for Android is the Android client for the widely-used, high-performance encryption protocol project Shadowsocks. It is a secure socks5 proxy for Android that is designed to protect your internet traffic. Shadowsocks for Android allows you to surf the internet privately and securely at all times through your Android device. It features bleeding-edge techniques with Asynchronous I/O and Event-driven programming. It is completely free and open-source and is available for other platforms as well.

ccrypt is a command-line tool for encrypting and decrypting files and streams. It provides strong encryption based on the Rijndael cipher, a version of which is also used in the Advanced Encryption Standard.

Cryptomator is a free and open source project that offers multi-platform, transparent client side encryption of your files in the cloud. It works with just about any cloud storage service; is totally transparent so you can work with your files how you normally would; and secure with a 256-bit key length AES encryption. It’s also simple and easy to use with no need for different accounts, key management, cloud access grants or cipher configurations.

ShadowsocksX-NG is the new ShadowsocksX, a secure socks5 proxy for accessing restricted sites or services on macOS. ShadowsocksX-NG was created separately from the original implementation as there had been too much unused code and dependencies of the ss-local source code in the original that had to be maintained. As such it was difficult to update. ShadowsocksX-NG has just a copy of ss-local from Homebrew, and its GUI code has been rewritten in Swift. It now runs as a background service rather than an in-app process, so the ss-local may still be running even after you quit the app. ShadowsocksX-NG also has an added manual mode so you can configure your apps to use the socks5 proxy manually without configuring the system proxy settings.

PLEASE NOTE that we are in the process of moving to GitHub: https://github.com/jasypt/jasypt Jasypt (Java Simplified Encryption) is a java library which allows the developer to add basic encryption capabilities to his/her projects with minimum effort, and without the need of having deep knowledge on how cryptography works.

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.

Pyton GnuPGInterface is meant to be a filehandle-concentrating Python interface to GnuPG, the GNU Privacy Guard. It has an API similar to the Perl module GnuPG::Interface.

GPGrelay is a small email-relaying server that uses GnuPG (the GNU Privacy Guard) to sign/encrypt (SMTP-Relay) or verify/decrypt (POP3-/IMAP-Relay) emails. This enables many email-clients to send and receive emails that are PGP-MIME conform.

pgpenvelope is an interface between Pine and the GNU Privacy Guard (GnuPG). It allows one to perform expected OpenPGP-related operations on messages. Ease of installation, setup, and use are distinguishing features.

Crypto++ is a free C++ class library of cryptographic schemes originally written by Wei Dai. The library is now maintained by a community of volunteers. The Crypto++ website is located at https://cryptopp.com/, and the source code is located at https://github.com/weidai11/cryptopp. The repository was moved in response to developer requests for Git access. The SourceForge site will remain in "read only" mode for historical purposes. You should visit the Crypto++ website at https://cryptopp.com/ or GitHub at https://github.com/weidai11/cryptopp to view the latest news, download the latest source code, file bugs and request features. We thank SourceForge for hosting us through the years.

axTLS is a TLSv1 SSL library designed specifically for embedded devices, with a highly configurable interface for small memory footprints.

The Kryptos Project began at George Mason University. The idea was to develop educational software that could be used to further break down and study different aspects of the implementation of cryptography.

FileVerifier++ is a Windows utility for calculating hashes using a number of algorithms including CRC32, MD5, SHA-1, SHA-256/224/384/512, WHIRLPOOL, and RIPEMD-128/160/256/320. Supported hash file formats include MD5SUM .MD5, SFV, BSD CKSUM, and others.

The OpenSC project allows the use of PKCS #15 compatible SmartCards and other cryptographic tokens (e.g. the Aladdin eToken) in UNIX compatible operating systems. OpenSC can use PC/SC Lite or CT-API as its reader backend. https://github.com/OpenSC/OpenSC/wiki/OpenSC-Services
