		+	codeSigning: This indicates that the certificate can be used for code signing.

		+	You can specify multiple usages by separating them with commas in the extendedKeyUsage extension field. For example, to allow both server authentication and client authentication, you would use extendedKeyUsage = serverAuth,clientAuth.
