Pass a Java Class as a parameter in a function

I need help passing a Java class as an argument to a specific Java method. The method in question is getKeySpec() from the java.security.KeyFactory class:

getKeySpec(Key key, Class<T> keySpec)

In the NativeScript Typings, the signature for this method is:

public getKeySpec(param0: java.security.Key, param1: java.lang.Class<any>): java.security.spec.KeySpec;

I am unsure of how to pass a java.lang.Class<any> to this method specifically when I want to use

java.security.spec.X509EncodedKeySpec
.

The current challenge lies within my TypeScript code, which fails at the point of calling getKeySpec().

function getPublicKey(keyPair: java.security.KeyPair): string {
    const kf = java.security.KeyFactory.getInstance("RSA");
    let pubKeySpec = kf.getKeySpec(keyPair.getPublic(), java.security.spec.X509EncodedKeySpec);
    return pubKeySpec.getEncoded();
}

Answer №1

Thumbs up

Obtain the public key specification using getKeySpec method with X509EncodedKeySpec class.
