Understanding cryptographic requirements
When using asymmetric encryption, we need an algorithm that can generate a mathematically related key pair. In this section, we'll take a look at some of the cryptographic requirements of using an asymmetric algorithm, and we'll see an example of generating a key pair. We'll then discuss the importance of managing the public and private key, and finish with ways we can use asymmetric encryption.
Let's start with some requirements when generating a key pair.
Designing a strong algorithm
When something is strong it is resistant to being broken, such as an impenetrable fortress. An encryption algorithm is no exception, in that we want one that is able to withstand a brute-force attack and continue to provide data confidentiality and integrity. Some of the considerations when designing a strong asymmetric algorithm include the following:
- It must be effortless to generate a mathematically related public and private...
