On a project I was asked to

a- Compute SHA-256 of a password
b- Do a BigInteger, convert to Hex String
c- Encrypt the key using a public key with the following parameters
  Entropy: I'm given some numbers
  Modulus: also given long numbers

[encrypt using RSA algorithm]

So far I'm familiar with a and b in Dlang.

how do I go about c) In Dlang ?

Thanks

I hope it's for a school project since I wouldn't recommend doing that in production.

However you can do c) either by implementing RSA (it's rather easy to badly implement RSA which could be enough at school level) or by using a library (I recommend the library).

There are several cryptographic libraries on https://code.dlang.org that implement RSA, botan and crypto for example. I'd trust botan more at the moment though I don't think any D library has received a proper cryptographic audit at the moment.

It is exponent not entropy
