OpenSSL::X509::Extension.new asn1 Show source
OpenSSL::X509::Extension.new name, value
OpenSSL::X509::Extension.new name, value, critical

Creates an X509 extension.

The extension may be created from asn1 data or from an extension name and value. The name may be either an OID or an extension name. If critical is true the extension is marked critical.
