无法使用scala解密OpenSSL生成的私钥

Question

我已经使用openssl生成了一个私钥，并在Terminal/command中执行以下命令：

null

所有这些都无法解密我的密钥。下面是我根据这篇文章编写的类[https://stackoverflow.com/questions/35276820/decrypting-an-openssl-pem-encoded-rsa-privest-key-with-java]:

private val random = new SecureRandom()

@throws(classOf[GeneralSecurityException])
def decrypt(keyDataStr: String, ivHex: String, password: String)
{
    val pw = password.getBytes(StandardCharsets.UTF_8)
    val iv = h2b(ivHex)
    val secret = opensslKDF(pw, iv)
    val cipher = Cipher.getInstance("AES/CBC/PKCS5Padding")
    cipher.init(Cipher.DECRYPT_MODE, secret, new IvParameterSpec(iv))
    val keyBytes = Base64.getMimeDecoder.decode(keyDataStr)
    val pkcs1 = cipher.doFinal(keyBytes)
    /* See note for definition of "decodeRSAPrivatePKCS1" */
    val spec = decodeRSAPrivatePKCS1(pkcs1)
    val rsa = KeyFactory.getInstance("RSA")
    rsa.generatePrivate(spec).asInstanceOf[RSAPrivateKeySpec]
}

@throws(classOf[NoSuchAlgorithmException])
private def opensslKDF(pw: Array[Byte], iv: Array[Byte]): SecretKeySpec = {
    val md5 = MessageDigest.getInstance("MD5")
    md5.update(pw)
    md5.update(iv)
    val d0 = md5.digest()
    md5.update(d0)
    md5.update(pw)
    md5.update(iv)
    val d1 = md5.digest()
    val key = new Array[Byte](24)
    System.arraycopy(d0, 0, key, 0, 16)
    System.arraycopy(d1, 0, key, 16, 8)
    new SecretKeySpec(key, "AES")
}

private def h2b(s: CharSequence): Array[Byte] = {
  val len = s.length();
  val b = new Array[Byte](len / 2)
  var src = 0
  var dst = 0
  while ( {
    src < len
  }) {
    val hi = Character.digit(s.charAt({
      src += 1; src - 1
    }), 16)
    val lo = Character.digit(s.charAt({
      src += 1; src - 1
    }), 16)
    b(dst) = (hi << 4 | lo).toByte

    dst += 1
  }
  b
}

def decodeRSAPrivatePKCS1(encoded: Array[Byte]) = {
  val input = ByteBuffer.wrap(encoded)
  if (der(input, 0x30) != input.remaining()) {
    throw new IllegalArgumentException("Excess data")
  }
  if (!BigInteger.ZERO.equals(derint(input))) {
    throw new IllegalArgumentException("Unsupported version")
  }
  val n = derint(input)
  val e = derint(input)
  val d = derint(input)
  val p = derint(input)
  val q = derint(input)
  val ep = derint(input)
  val eq = derint(input)
  val c = derint(input)
  new RSAPrivateCrtKeySpec(n, e, d, p, q, ep, eq, c)
}

private def derint(input: ByteBuffer): BigInteger = {
  val len = der(input, 0x02)
  val value = new Array[Byte](len)
  input.get(value)
  new BigInteger(+1, value)
}

private def der(input: ByteBuffer, exp: Int): Int = {
  val tag = input.get() & 0xFF
  if (tag != exp) {
    throw new IllegalArgumentException("Unexpected tag")
  }
  var n = input.get() & 0xFF
  if (n < 128) {
    n
  }
  else {
    n &= 0x7F
    if ((n < 1) || (n > 2)) {
      throw new IllegalArgumentException("Invalid length")
    }
    var len = 0
    for (i <- 0 to n) {
      len <<= 8
      len |= input.get() & 0xFF
    }
    len
  }
}

def alphanumeric(nrChars: Int = 24): String = {
  new BigInteger(nrChars * 5, random).toString(32)
}

我对安全问题一无所知，所以我需要这方面的帮助。提前谢了。

决定放弃我发布并使用BouncyCastle的方法。这里的示例代码。

对于像我这样的低温描记技术一无所知的人来说容易多了。
