You can use an electronic signature for code signing on macros, applets, and software. When you sign these types of data it informs users that they can trust your applications. You can authenticate the software or macro with the issuer and remove security warnings by using this method. The e-signature will need to be encrypted into a digital certificate as a digital signature in order to enable code signing.
An Electronic Signature Can Be Secured Using SSL Encryption
An alternative method to using a digital signature is to use SSL encryption with your electronic signature. SSL encryption creates a secure connection over shared and public networks using a SSL certificate. SSL can be used with your file uploads and downloads, websites, email and other types of electronic connections. Each type of application should have its own SSL certificate.
