The 'jsrsasign' (RSA-Sign JavaScript Library) is an opensource free cryptography library supporting RSA/RSAPSS/ECDSA/DSA signing/validation, ASN.1, PKCS#1/5/8 private/public key, X.509 certificate, CRL, OCSP, CMS SignedData, TimeStamp, CAdES and JSON Web Signature/Token in pure JavaScript.

X Certificate and Key management

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.

A library for certificate revocation checking

The fetch-crl utility will retrieve certificate revocation lists (CRLs) for a set of installed trust anchors, based on crl_url files or IGTF-style info files. It will install these for use with OpenSSL, NSS or third-party tools.

This script parses PEM or DER certificates, requests, CRL's, PKCS#12, PKCS#7 & PKCS#8 files, Java keystores, NSS databases, Diffie-Hellman / DSA / Elliptic Curve parameters and private & public keys (from OpenSSH too). It uses OpenSSL for most operations (unless the openssl variable is empty), otherwise it uses GnuTLS' certtool. If the certtool …

The node module that allows you to control your Ethereum revocation lists & resolve revocation keys.
