Encryptions were really interesting to me. I did not realize there were so many different “styles” if you will. RSA or Rivest Shamir Adleman could be used to submit data over the internet. It lets the input of data be “password free”. However, the end user or receiving side need a “pass word” to be able to get the data. This way you have control over who is able to open/view the data you are sending out. Websites is a great place for this to be used, or emails. ECC has a smaller size, meaning it is great for less powerful machines like cell phones or tablets. The next one that peaked my interest was AES I could see this being used in a business setting where data is being exchanged with servers/or storage systems. That way it takes special access to input and export. I could also see this being used as a way for a potential contractor to make sure that a customers data is secure between both contractor and supplier.
