I'm building an application that needs to store a public/private key pair generated by the user. What's the best way to do this? Encrypt the private key in the db with some application-generated secret? Encrypt the private key with some user-specific secret?
Homework Answers
Short answer : you don't. Private keys are , by definition, meant to remain private. If you need to store a secret for each user, the odds are symmetric encryption is a better fit.
You should edit your quetstion with more details about what you're trying to accomplish. If there's a flaw in your design as I guess, we can provide you advice to make it better. And if you actually happen to have a good reason to store a user's private key I'd be very interested in reading it.

Write a program to peform a database backup. Generate a public/private key pair (using GnuPG, or anything else). Your backup program/script must run daily, backup a table in a database into a .csv.gz file (comma delimited, gzip compressed [do not use database specific binary formats]). And encrypt the backup using your PUBLIC key. Note that you can use any language, database, utility, configuration, etc. (cron script or windows scheduler is ok). The key is that the backup is comma delimited...

forehand e receiver creates a public key and a secret key as follows. Generate two distinct primes, p andq. Since they can be used to generate the secret key, they must be kept hidden. Let n-pg, phi(n) ((p-1)*(q-1) Select an integer e such that gcd(e, (p-100g-1))-1. The public key is the pair (e,n). This should be distributed widely. Compute d such that d-l(mod (p-1)(q-1). This can be done using the pulverizer. The secret key is the pair (d.n)....

I have a text file that this project needs to read from that has every possible combination of words but I am unsure how to do it. Also I'm pretty sure this program could use a program called "myArraylist" to sort through the text file but I am unsure how to implement this. I am unsure how to show the text file because it is massive, and I don't think it is possible to upload a text file to chegg....
