    assertThatExceptionOfType(BadJwtException.class).isThrownBy(() -> decoder.decode(this.messageReadToken).block()).havingRootCause().withMessage("Required JOSE header typ (type) parameter is missing");
// @formatter:on
}

Example 48 with Decoder

use of java.util.Base64.Decoder in project vorto by eclipse.

the class PublicKeyHelper method toPublicKey.

public static PublicKey toPublicKey(String mod, String exp) {
    try {
        Decoder urlDecoder = Base64.getUrlDecoder();
        BigInteger modulus = new BigInteger(1, urlDecoder.decode(mod));
        BigInteger publicExponent = new BigInteger(1, urlDecoder.decode(exp));
        KeyFactory kf = KeyFactory.getInstance("RSA");
        return kf.generatePublic(new RSAPublicKeySpec(modulus, publicExponent));
    } catch (Exception e) {
        throw new InvalidTokenException("Problem converting the common keys to public keys", e);
    }
}

Example 49 with Decoder
