**How to choose the best encryption algorithm? **

Now, we can see in what way encryption algorithms are selected. Here, we have specified the parameters that are used to **evaluate the efficiency of the algorithm using encryption simulator**. Only a few cryptography algorithms are dependent on complex mathematics.** For instance: **While you are dealing with quantum cryptography algorithms, there are several metrics to evaluate various nature of problems. Some of the metrics are

To select **optimal symmetric key encryption, analyze several elements of cryptosystems**. As well, they are tolerant against attacks **(known and chosen plain text attacks, differential, and exhaustive attacks, ciphertext only attacks, etc.),** long-secret keyspace, encryption effect, and other statistical analysis methods.
