Digital signatures work because public key cryptography depends on two mutually authenticating cryptographic keys. The individual who is creating the digital signature uses their own private key to encrypt signature-related data; the only way to decrypt that data is with the signer's public key.

Where is digital signature used?

You can use Digital Signature Certificates for the following: For sending and receiving digitally signed and encrypted emails. For carrying out secure web-based transactions, or to identify other participants of web-based transactions.

How is a digital signature created?

To create a digital signature, signing software -- such as an email program -- creates a one-way hash of the electronic data to be signed. The private key is then used to encrypt the hash. The encrypted hash -- along with other information, such as the hashing algorithm -- is the digital signature.

What does it mean to digitally sign a document?

The learning curve is fairly easy and short. Still learning features as I go. I use the program every two weeks and generate four documents each time. I've been able to look up every document that I have needed and able to open and edit and print. There are occasions that he document will cut off part of the header or will not allign the text correctly. However, that's about 3% (or less) of the time.

Great Product I am able to complete many forms without having to use more complex programs. The ability to find and fill out form not available other wise. Some searches turn up rather strange results.

Very helpful tool, and easily accessible on the go! Great tool and helpful to keep business going while traveling or on the go. Simple, easy to use format. I could access it while on the go and get work done without having to log into my laptop. When trying to "save as", it takes a few more steps than I'd like it to.

A solid editor with a very minor flaw imo Other than a better scroll bar for the area of the documents being edited, the interface is pretty easy to navigate if you have used any similar programs (such as adobe acrobat reader). I wish there was a less feature oriented version that was free to use/download, perhaps with a daily/weekly task limit, similar to things like smallpdf.
