Encryption KeysMost programming language can only deal with 64-bit integers. If we need to deal with larger ones, we need to use additional libraries, such as Bouncy Castle, where we can declare Big Integers, such as: Org.BouncyCastle.Math.BigInteger b = new Org.BouncyCastle.Math.BigInteger("2"); Using this code, this program uses Bouncy Castle to calculate the number of keys for various key sizes:
