Hi, my name is Harry. In this blog, I will explain about the digital signature and how it works. <\/p>\n\n\n\n

The digital signature<\/strong> is a fixed-length produced from a hash function value that is encrypted with a private key. This digital signature act as a stamp of approval for the software, documents, or a message. Technically, when something is digitally signed it ensures that came from the original publisher and protects from alteration after publication.<\/p>\n\n\n\n

Why is it important to know about this?<\/strong><\/h3>\n\n\n\n

Well, imagine if you downloaded a software, you want to make sure it legally came from the original publisher, company or vendor before installation. When a software publisher wants its product legitimacy and integrity then a digital signature must be obtained.<\/p>\n\n\n\n
