使用ckosshtunnel和AuthenticatePk进行身份验证失败或部分成功

Question

我遇到了一个问题，我可以通过公钥通过命令行连接到ssh服务器：

ssh -N -L 12345:127.0.0.1:22 -i /Users/kylehankinson/.ssh/id_rsa USER@HOST

但是如果我通过代码尝试同样的事情：

CkoSshKey * sshkey = [[CkoSshKey alloc] init];
sshkey.Password = @"blahblah";

NSString * privateKeyString = [sshkey LoadText: @"/Users/kylehankinson/.ssh/id_rsa"];

if(![sshkey FromPuttyPrivateKey: privateKeyString])
{
    NSLog(@"Had failure: %@", sshkey.LastErrorText);
    return;
}

CkoSshTunnel *ssh = [[CkoSshTunnel alloc] init];
success = [ssh Connect: @"HOST" port: @(22)];
if (success != YES)
{
    NSLog(@"%@",ssh.LastErrorText);
    return;
}

success = [ssh AuthenticatePk: @"USER"
                   privateKey: sshkey];
if(!success)
{
    NSLog(@"%@",ssh.LastErrorXml);
    return;
}

我收到以下错误：

有什么建议吗？

谢谢凯尔

这里有一个新的构建来解决这个问题：https://chilkatdownload.com/prerelease/chilkat-9.5.0-macosx-objc-1408.zip

问题的根源与OpenSSH密钥格式中的私钥blob格式有关。解析RSA密钥部分的顺序不正确。(如果密钥是从PuTTY私钥格式.ppk加载的，则没有问题。)
