I started Working On a encryption project, but I am facing a problem with the leak of encryption keys. Is there a list of the most popular encryption keys used, like the password lists of most used passwords?
Keys differ significantly from the passwords. Key can be derived from password (for example via PBKDF2), but it is not some value that is chosen by programmer, it is generated by computer, and (if correctly implemented) partially or wholly random.
I doubt that there are some "often used" keys, since they are basically big random numbers.
