Q. What is a Digital Signature?
A digital signature is a message digest used to cryptographically sign a message.
Digital signatures rely on asymmetric or public key, cryptography.
To create a digital signature, you sign the message with your private key. The digital signature then becomes part of the message.
This has two effects:
• Any changes to the message can be detected, due to the message digest algorithm.
• You cannot deny signing the message, because it was signed with your private key.
These two features, message integrity and non-repudiation, make digital signatures a very useful component for e-commerce applications

It's a good helpful information for beginners about digital signature software, although e-commerce, where it's also applied, is a very broad topic.
