我有一个私人/公钥对，由其他人生成并传给我 . 该对目前用于主动部署 . 两个密钥都存储在扩展名为.der的文件中 . 私钥我可以验证并解析好吧：

openssl pkcs8 -inform DER -nocrypt -in private_key.der

然而，公共的失败了：

解密密钥错误139834801850032：错误：0D0680A8：asn1编码例程：ASN1_CHECK_TLEN：错误标记：tasn_dec.c：1338：139834801850032：错误：0D06C03A：asn1编码例程：ASN1_D2I_EX_PRIMITIVE：嵌套asn1错误：tasn_dec.c：852：139834801850032：错误：0D08303A：asn1编码例程：ASN1_TEMPLATE_NOEXP_D2I：嵌套asn1错误：tasn_dec.c：772：Field = version，Type = PKCS8_PRIV_KEY_INFO

公钥当前由java应用程序使用，并按如下方式加载：

byte[] publicKeyArray - <the public key bytes straight from file>
     X509EncodedKeySpec spec = new X509EncodedKeySpec(publicKeyArray);
     KeyFactory factory = KeyFactory.getInstance("RSA");

     java.security.PublicKey publicKey = factory.generatePublic(spec);

X509EncodedKeySpec的类文档如下：

* This class represents the ASN.1 encoding of a public key,
 * encoded according to the ASN.1 type {@code SubjectPublicKeyInfo}.
 * The {@code SubjectPublicKeyInfo} syntax is defined in the X.509
 * standard as follows:
 *
 * <pre>
 * SubjectPublicKeyInfo ::= SEQUENCE {
 *   algorithm AlgorithmIdentifier,
 *   subjectPublicKey BIT STRING }
 * </pre>

和：

* Creates a new X509EncodedKeySpec with the given encoded key.
     *
     * @param encodedKey the key, which is assumed to be
     * encoded according to the X.509 standard. The contents of the
     * array are copied to protect against subsequent modification.
     * @exception NullPointerException if {@code encodedKey}
     * is null.
     */

我试过尝试不同的openssl命令，包括asn1parse但没有运气 . 如何使用java X509EncodedKeySpec以外的其他东西从我的文件中使用/提取公钥？

java openssl public-key
