Digital Transformation - Authenticity of senders & integrity of data, using Digital Signatures

Important factors which determine the quality of our digital transformation efforts, are the security best practices that we follow. Dig-Sigs are easy to use and must be used more widely by developers and architects.

Digital signatures are the easiest way to verify authenticity of the sender and maintain integrity of data transmitted, when data is transferred over an untrusted network be it the web, email, chat, meetings, video calls, etc.

For wider adoption of this important digital weapon in our arsenal, the trick is to convince our developers how 'easy and simple' it is to sign documents and indeed any data.
