I'm attempting to encrypt some information into our database to be later pulled back out and displayed to the user. Searching and reading up on different methods I found a post over at stack exchanged with example code for doing AES Encryption.
Reading through the comments and some different articles I've come to realize that using a static IV for your encryption is generally poor form. That using a random IV is better. This would make sense, but to my understanding I need a way to find that IV again in order to be able to decrypt the information.
I would believe that I can't store the IV in my DB as well, since that would defeat the whole purpose of this. The only thing I can think of is to use something in the row (e.g. a Datetime) as a seed for a random number generator. Which would generate the same IV every time, but that doesn't seem that secure to me either if anyone figured that out.
What are the best practices for situations like this?
