See for yourself by reading reviews on the most popular resources:
I experienced quite a steep learning curve. Meaning, the directions I would have found easier to follow would be in steps...step 1, then step two, etc. In other words, the program was really user friendly to first time user. Also, I thought I signed on for a5.95 one month contract that I could cancel at any time. Why am I being charge19.95 Please answer this question. Thank you

Outstanding Online Support I have used Pdffiller for the past 4 years to file tax returns for an investment group with over 40 members. I made an error when creating my template and when I went to print the 40 documents an erroneous number was appearing, the result of my error in creating the document. Fortunately Pdffiller has an online support staff. So many online companies require you to submit a ticket and then promise a 24 to 48 hour response time. Pdffiller offers that option but they have an outstanding online chat support. I had the benefit of working with Ryan and got access to him immediately upon opening up the online chat support. This was in the evening but Ryan thoroughly researched and tested my issue. Sadly the only option that appeared to be the answer was to create a new set of 40 documents which Ryan was willing to teach me how to create the docs in way that would avoid this error. When I expressed my issue with not having another 6 hours to re-create my work, Ryan persisted in finding a work around that was very creative and saved me from over six hours of new work!!! Needless to say I was ecstatic!!! Thank you Pdffiller for not only a great product but an online support staff that truly cares about helping customers get the results they require!!

Great tool in a pinch! The google chrome extension worked really well since you can't just click on something in drive and easily open it - and I've had issues with Adobe for some time. This software did what I needed it to do multiple times. This is typically slow to open, and saving & retrieving files is a bit clunky.

It is a little bit confusing on how the program works. I have been trial and error learning so far. It would be nice to get more direction and not just comment bubbles.

Other than being billed initially for a 30 days trial, I contacted Customer Service right away and they credited me back the $144 first year right away. Otherwise, I am liking the service so far. Just learning how to use it.

You will need to have OpenSSL installed. Open a command prompt window and go to the directory you created earlier for the public/private key file. Enter the path of the OpenSSL install directory, followed by the self-signed certificate algorithm.
Although the makeup of an SSL certificate consists of a private and public key, the SSL certificate itself is sometimes referred to as “the public key.” The SSL certificate is also referred to as the “end entity” certificate since it sits at the bottom of the certificate chain and is not used for signing/issuing other
A certificate contains a public key. The certificate, in addition to containing the public key, contains additional information such as issuer, what the certificate is supposed to be used for, and other types of metadata. Typically, a certificate is itself signed by a certificate authority (CA) using CA's private key.
A public key certificate is a digitally signed document that serves to validate the sender's authorization and name.
A public key certificate can be thought of as the digital equivalent of a passport. It is issued by a trusted organization and provides identification for the bearer. A trusted organization that issues public key certificates is known as a certificate authority (CA). The CA can be likened to a notary public.
Step 1: Install SSL Certificate. Step 2: Export SSL Certificate (with Private Key) using Internet Explorer. Step 3: Install SSL Certificate on Server.
