A native implementation of TLS in Javascript and tools to write crypto-based and network-heavy webapps

PKI.js is a pure JavaScript library implementing the formats that are used in PKI applications (signing, encryption, certificate requests, OCSP and TSP requests/responses). It is built on WebCrypto (Web Cryptography API) and requires no plug-ins.

CAdESjs is an implementation of CAdES (CMS Advanced Electronic Signatures)in pure Javascript.

Маленькая библиотека для работы с CryptoPro-шными сертификатами в контексте CRL, CRLDP на IBM JVM. (Для сертификатов CryptoPro с OCSP это неактуально). Криптопровайдер при этом JCP, bouncy-castle используется только для работы с ASN.1 где использование jcp-шных классов было затруднено. Но Вы вправе это исправить и сделать свой вклад в библиотеку.

The QR-CERT software is a specialized package of applications dedicated for the development of a Public Key Infrastructure system as well as the cards personalization and management system. The software contains a number of functional modules, enabling a flexible selection of functionalities for implementation. The software is dedicated for large organizations and corporate environments, with a PKI infrastructure and microprocessor cards. The QR-CERT is a solution both for the companies which plan to build their own PKI infrastructure and entities planning to provide services in this respect. This software enables the implementation of advanced security mechanisms, such as: secure e-mail (S/MIME), electronic signature (PKCS#7, XAdES), network transmission protection (IPSEC, SSL/TLS) and strong authentication for service portals (HTTPS) or strong authentication of users for the Windows ActiveDirectory domain.
