Sergey Beryozkin commented on CXF-7005:
---------------------------------------
Hi
We'd like to get Fediz (1.3.2) earlier than usual which depends on CXF so
hopefully we may have 3.1.8 released
in mid September, in about 4-5 weeks, though I can't guarantee. Please stress
some more JOSE code in meantime :-)
thanks
> NullPointerException when using JwkUtils.toRSAPrivateKey

> Key: CXF-7005

> Project: CXF
> Issue Type: Bug
> Components: JAX-RS Security
> Affects Versions: 3.1.7
> Reporter: Behrang Saeedzadeh
> Assignee: Sergey Beryozkin
> Fix For: 3.2.0, 3.1.8

> When an RSA private key is converted to a JWK and stored in a JSON Web Keys
> file using the following code:
> {code}
> import test.CryptoUtils; // loads an RSA private key from file
> import org.apache.cxf.rs.security.jose.jwk.JsonWebKey;
> import org.apache.cxf.rs.security.jose.jwk.JsonWebKeys;
> import org.apache.cxf.rs.security.jose.jwk.JwkUtils;
> import java.io.FileNotFoundException;
> import java.io.FileOutputStream;
> import java.io.IOException;
> import java.nio.file.Paths;
> import java.security.interfaces.RSAPrivateKey;
> import java.time.LocalDateTime;
> public class JwkCreator {
> public static void main(String[] args) throws IOException {
> final RSAPrivateKey privateKey =
> CryptoUtils.loadRsaPrivateKey(Paths.get("private-key.der"));
> final JsonWebKey jwk = JwkUtils.fromRSAPrivateKey(privateKey,
> "RSA-OAEP-256");
> jwk.setKeyId("test");
> final JsonWebKeys webKeys = new JsonWebKeys(jwk);
> JwkUtils.jwkSetToJson(webKeys, new FileOutputStream("jwk.json"));
> }
> }
> {code}
> The generated file does not have a {{RSA_PUBLIC_EXP}} (i.e. the `e`) property:
> {code}
> {
> "keys": [
> {
> "kty": "RSA",
> "alg": "RSA-OAEP-256",
> "n": "...",
> "d": "...",
> "p": "...",
> "q": "...",
> "dp": "...",
> "dq": "...",
> "qi": "...",
> "kid": "test"
> }
> ]
> }
> {code}
> Consequently, when trying to use {{JwkUtils.toRSAPrivateKey}} to convert the
> JWK to a private key, a NullPointerException is thrown due to the following
> statement in {{JwkUtils.java}}:
> {code}
> return CryptoUtils.getRSAPrivateKey(encodedModulus,
> encodedPublicExponent,
> encodedPrivateExponent,
> encodedPrimeP,
> encodedPrimeQ,
> encodedPrimeExpP,
> encodedPrimeExpQ,
> encodedCrtCoefficient);
> {code}
> which in turn calls {{CryptoUtils.decodeSequence(encodedPublicExponent)}} on
> a {{null}} value.
