## Getting started

You can use swift-jwt with any cryptography library you like! One such library is [swift-cryptography](https://github.com/rarestype/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`](https://swiftinit.org/docs/swift-cryptography/cryptography/rsa/privatekey) type:

```swift

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`.
