Getting started

You can use swift-jwt with any cryptography library you like! One such library is swift-cryptography. If you do choose to use swift-cryptography, here’s how you would sign some JSONEncodable payload, using that library’s RSA.PrivateKey type:

import Cryptography
import JSON
import JWT

extension RSA.PrivateKey {
    func jwt(signing claims: some JSONEncodable) throws -> String {
        let header: JSON.WebTokenHeader = .init(alg: .rs256)
        return try header.sign(encoding: claims) {
            try self.sign(hashing: $0[...], padding: .pkcs1_legacy, algorithm: .sha256)
        }
    }
}

But really, you could use any cryptography library you like, as long as it can sign a String.
