Probably the best way is to use PBKDF2 using SHA256 (which will generate 256 bit output) and a application specific salt & iteration count. You should be aware that using an application specific salt removed quite a lot of the protection from PBKDF2, so you may require additional protection to alleviate this issue. Oct 15, 2017 In simple words AES-256 encryption (Advanced Encryption Standard), is a method to generate key securely to encrypt the data and prevent it from unwanted access to that data. In this AES-256 bit encryption, the 256-bit is the key which is referred. An AES key, and an IV for symmetric encryption, are just bunchs of random bytes. So any cryptographically strong random number generator will do the trick. OpenSSL provides such a random number generator (which itself feeds on whatever the operating system provides, e.g. CryptGenRandom on Windows or /dev/random and /dev/urandom on Linux). Jun 17, 2013 Encrypt, decrypt and generate a key in C# using AES256. This might be a noob question, but I couldn't find its answer anywhere online: why does an OpenSSL generated 256-bit AES key have 64 characters? The command I'm using to generate the key is: $ ope.
