Kenji Urushima

Tokyo, Japan

Hello, I'm Kenji Urushima and the developer of the 'jsrsasign' pure JavaScript PKI, cryptography and security library. More funding is allowing more time to work on major architecture design updates, urgent security fixes, new features, documents, samples and user support. Please consider sponsoring if you want to be a part of the project.

Future Plan for jsrsasign

  • modern JavaScript coding
  • modular design: Some people complains this library is so huge to download. Someone may want to use just for JWT. So this library shall be separated in modules.
  • more cryptographic algorithm support: add missing algorithms such as AES-GCS, EdDSA or more EC curves.
  • simple and/or full RFC 5280 certification path validation
  • more X.509 v3 extensions
  • CAdES-A support
  • encrypted JWT and JWE support
  • simple OCSP responder server
  • simple Timestamp server
  • ASN.1 BER support
  • yet another ASN.1 dumper like asn1js decoder
  • online tool pages for mobile

Another Project: SSL Pulse Trends

This project shows trend data of Qualys SSL Pulse site from 2012. Analyzed data will be updated every month. This also needs your support.
