SPKAC is a Certificate Signing Request mechanism originally implemented by Netscape and was specified formally as part of HTML5's
keygenelement.<keygen>is deprecated since HTML 5.2 and new projects should not use this element anymore.The
node:cryptomodule provides theCertificateclass for working with SPKAC data. The most common usage is handling output generated by the HTML5<keygen>element. Node.js uses OpenSSL's SPKAC implementation internally.Since
