sjcl - Stanford Javascript Crypto Library


The Stanford Javascript Crypto Library is a project by the Stanford Computer Security Lab to build a secure, powerful, fast, small, easy-to-use, cross-browser library for cryptography in Javascript. SJCL is secure. It uses the industry-standard AES algorithm at 128, 192 or 256 bits; the SHA256 hash function; the HMAC authentication code; the PBKDF2 password strengthener; and the CCM and OCB authenticated-encryption modes.

openpgpjs - OpenPGP implementation for JavaScript


This project aims to provide an Open Source OpenPGP library in JavaScript so it can be used on virtually every device. This does not require gpg on their machines in order to use the library. The idea is to implement all the needed OpenPGP functionality in a JavaScript library that can be reused in other projects that provide browser extensions or server applications. It should allow you to sign, encrypt, decrypt, and verify any kind of text - in particular e-mails - as well as managing keys.

BouncyCastle - Lightweight Cryptography API for Java and CSharp


Bouncy Castle Crypto APIs is a lightweight cryptography API for Java and CSharp. It has provider for the Java Cryptography Extension and the Java Cryptography Architecture. It supports TLS, PKCS7, PKCS12, OpenPGP, S/MIME, OCSP, TSP, CMP, Extended Access Control, ASN and lot more.

WinSCP - Free SFTP, SCP and FTP client for Windows


WinSCP is an open source free SFTP client, SCP client, FTPS client and FTP client for Windows. Its main function is file transfer between a local and a remote computer. Beyond this, WinSCP offers scripting and basic file manager functionality.




OpenSSL - Toolkit for SSL and TLS


The OpenSSL Project is a collaborative effort to develop a robust, commercial-grade, full-featured, and Open Source toolkit implementing the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) protocols as well as a full-strength general purpose cryptography library.

SoftU2F - Software U2F authenticator for macOS


Soft U2F is a software U2F authenticator for OS X. It emulates a hardware U2F HID device and performs cryptographic operations using the OS X Keychain. This tool works with Google Chrome and Opera's built-in U2F implementations as well as with the U2F extensions for OS X Safari and Firefox.We take the security of this project seriously. Report any security vulnerabilities to the GitHub Bug Bounty Program.

tendermint - Tendermint Core (BFT Consensus) in Go


Byzantine-Fault Tolerant State Machine Replication. Or Blockchain for short.NOTE: This is alpha software. Please contact us if you intend to run it in production.



end-to-end - End-To-End is a crypto library to encrypt, decrypt, digital sign, and verify signed messages (implementing OpenPGP and OTR)


End-To-End is a crypto library to encrypt, decrypt, digital sign, and verify signed messages (implementing OpenPGP and OTR).This is the source code for the End-To-End library. It's built upon a newly developed, JavaScript-based crypto library. End-To-End implements the OpenPGP standard, IETF RFC 4880, enabling key generation, encryption, decryption, digital signature, and signature verification.

wycheproof - Project Wycheproof tests crypto libraries against known attacks.


Project Wycheproof is named after Mount Wycheproof, the smallest mountain in the world. The main motivation for the project is to have a goal that is achievable. The smaller the mountain the more likely it is to be able to climb it.Project Wycheproof tests crypto libraries against known attacks. It is developed and maintained by members of Google Security Team, but it is not an official Google product.

s2n - an implementation of the TLS/SSL protocols from Amazon


s2n is a C99 implementation of the TLS/SSL protocols that is designed to be simple, small, fast, and with security as a priority. s2n implements SSLv3, TLS1.0, TLS1.1, and TLS1.2. For encryption, s2n supports 128-bit and 256-bit AES, in the CBC and GCM modes, 3DES, and RC4. For forward secrecy, s2n supports both DHE and ECDHE.

NaCL - Networking and Crytography library


NaCl is a new easy-to-use high-speed software library for network communication, encryption, decryption, signatures, etc. NaCl provides a simple crypto_box function that does everything in one step. The function takes the sender's secret key, the recipient's public key, and a message, and produces an authenticated ciphertext.

SecureDrop - Whistleblower Submission System


SecureDrop is an open-source whistleblower submission system that media organizations can use to securely accept documents from and communicate with anonymous sources. It was originally created by the late Aaron Swartz and is currently managed by Freedom of the Press Foundation. Among the tools used in and around the SecureDrop application are: Tor, GnuPG encryption, Apache, OSSEC, grsecurity, Ubuntu, the Tails operating system, and an air-gap.
