Overview

Specifies the allowed usage purposes of the keypair specified in this certificate. Reference: Section 4.2.1.3 of RFC3280 tools.ietf.org/html/rfc3280#section-4.2.1.3

Note: OpenSSL when parsing an extension will return results in the form ‘Digital Signature’, but on signing you have to set it to ‘digitalSignature’. So copying an extension from an imported cert isn’t going to work yet.
