    - #### encodePrivateKey

          public static byte[] encodePrivateKey(AsymmetricKeyParameter params)
                                         throws java.io.IOException

      Encode a cipher parameters into an OpenSSH private key. This does not add headers like ----BEGIN RSA PRIVATE KEY----
      Parameters:
        `params` - the cipher parameters.
      Returns:
        a byte array
      Throws:
        `java.io.IOException`

    - #### parsePrivateKeyBlob

          public static AsymmetricKeyParameter parsePrivateKeyBlob(byte[] blob)

      Parse a private key.

      This method accepts the body of the OpenSSH private key. The easiest way to extract the body is to use PemReader, for example:

      byte[] blob = new PemReader([reader]).readPemObject().getContent(); CipherParameters params = parsePrivateKeyBlob(blob);

      Parameters:
        `blob` - The key.
      Returns:
        A cipher parameters instance.
