Minor Description
We can make key length configurable to be used with the RSA algorithm, so that Users can set the value as per current cryptography guidelines.
Also, in a password-based key derivation function, the base key is a password and the other parameters are a salt value and an iteration count. An iteration count has traditionally served the purpose of increasing the cost of generating keys from a password. We can keep the Scheme, Salt and Iteration Count configurable for Users to fine tune as per their requirements.
