I am on OS X 10.8.3, savvy with a command-line and I want to use OpenSSL to start encrypting sensitive information on my MacBook Pro
I know that I can use openSSL in a syntax like:
openssl enc -aes-256-ecb -in in.txt -out encrypted.txt
Can anyone explain what encryption type to use and why?
Also, Can I paste in a string to that openSSL command and get back an encrypted string to store in a file? (say a password list). Store each password encrypted in the text file and then encrypt the entire file as well.
I also assume that one can encrypt one way, then encrypt a second time using a different method for added protection.
if I encrypt this on OS X I also assume that I could decrypt it on Linux.
