java - 无法加载 RSA 公钥

Question

我正在尝试读取如下所示的 RSA 公钥，但在第 6 行出现异常:java.security.spec.InvalidKeySpecException: java.security.InvalidKeyException: IOException: algid parse error, not a sequence

我的代码:

String rsaPublicKey = rsaPublicKeyString.replace(
    "-----BEGIN RSA PUBLIC KEY-----\n", "");
rsaPublicKey = rsaPublicKey.replace("\n-----END RSA PUBLIC KEY-----", "");
byte[] bytes = EncryptionUtils.decodeBase64(rsaPublicKey);

KeyFactory keyFactory = KeyFactory.getInstance("RSA");
X509EncodedKeySpec keySpec = new X509EncodedKeySpec(bytes);
pubKey = (RSAPublicKey)keyFactory.generatePublic(keySpec);

RSA 公钥:

-----BEGIN RSA PUBLIC KEY-----

-----END RSA PUBLIC KEY-----

我做错了什么？

更新:

public static byte[] decodeBase64(String data) throws EncryptionException {
    try {
        BASE64Decoder decoder = new BASE64Decoder();
        return decoder.decodeBuffer(data);
    } catch (Exception e) {
        throw new EncryptionException(e);
    }
}

对我来说，我缺少公钥中的 OID。我必须使用此处的帮助在 iOS 端更正该问题:http://blog.wingsofhermes.org/?p=42

此外，我的公钥不必转换为 RSAPublicKey，标准工作得很好:

X509EncodedKeySpec pubKeySpec = new X509EncodedKeySpec(publicKeyBytes);
KeyFactory keyFactory = KeyFactory.getInstance("RSA");
PublicKey pubKey = keyFactory.generatePublic(pubKeySpec);
