I had to refile my last 4 years 1040 and all tax docs. After going through the IRS web docs but unable to edit them I found all the docs on the PDFfiller website. After a little work with the editors I was able to process professional docs. I bought a year sub and look to see if I can use this app for other business uses.

The only difficulty I encountered was figuring out how to find subsequent forms. I worked it out -= probably not in the most expeditious way - but I will happily use the service in the future.

Below is a list of the most common customer questions. If you can’t find an answer to your question, please don’t hesitate to reach out to us.
Generate an SSL Key File. Firstly you will need to generate a key file. Create a Certificate Signing Request (CSR) This step will create the actual request file that you will submit to the Certificate Authority (CA) of your choice. Install the Certificate (CRT) Test your installed Certificate.
SHA-256 is now the industry-standard signature hash algorithm for SSL certificates. SHA-256 provides stronger security and has replaced SHA-1 as the recommended algorithm. You can switch to SHA-256 when you renew your certificate, or you can replace your certificate at any time at no charge.
SHA2, not often used for now, is the successor of SHA1 and gathered 4 kinds of hash functions: SHA224, SHA256, SHA384 and SHA512. It works the same way as SHA1 but is stronger and generate a longer hash.
SHA-256. SHA stands for Secure Hash Algorithm. Cryptographic hash functions are mathematical operations run on digital data. By comparing the computed “hash” (the output from execution of the algorithm) to a known and expected hash value, a person can determine the data's integrity.
Additionally, SHA1 has also been deemed quite vulnerable to collision attacks which is why all browsers will be removing support for certificates signed with SHA1 by January 2017. SHA256 however, is currently much more resistant to collision attacks as it is able to generate a longer hash which is harder to break.
SHA is a popular hashing algorithm used by the majority of SSL certificates. As computing power has increased the feasibility of breaking the SHA1 hash has increased. Plans within the industry have been made to transition from SHA1 to SHA256 (SHA2). Some applications and devices can only support SHA1 certificates.
