SslKey on iOS, cannot read private key

[kolegs]

Hi,

I created SslServer using Qt and client, which works just fine on Ubuntu. The problem is when I try to port it to iOS.

When I try to connect I get error on client console: QAbstractSocket::SslInvalidUserDataError
After some more investigation I found out that iOS cannot load SslKey. It means I cannnot create correct QSslKey object. I can read the file with key, but when I run code:

QFile file;
file.setFileName(keyFilePath);
file.open(QIODevice::ReadOnly);
QSslKey key(file.readAll(), QSsl::Rsa);
file.seek(0);
qDebug() << key << file.readAll();
file.close();

What I get is

QSslKey(PrivateKey, RSA, -1) "----- BEGIN PRIVATE KEY-----
....
\n-----END PRIVATE KEY-----\n"

So it looks like Qt cannot read key
Any ideas?

EDIT: I forgot, the keys are self-signed, maybe that is the problem?

EDIT2: Just checked, it also works on Android

Hi,

Which version of Qt are you using ?

I tried both 5.5 and 5.6. And according to the documentation this versions are using Apple's Secure Transport API, what I can confirm using methods:

QSslSocket::supportsSsl()
QSslSocket::sslLibraryVersionString()
QSslSocket::sslLibraryBuildVersionString(

Also I checked that changing my server peer verification to VerifyNone works just fine. The problem is that iOS cannot load my ssl key and because of that server cannot verify user.
