Error Creating SSL Context - Qt

c++ qt openssl

Solution 1

At last, I found the solution. I was downloading dll's from a dll website. You need to take these libraries

- libeay32.dll
- libssl32.dll
- ssleay32.dll

from this website here Win32 OpenSSL v1.0.2 file for 32 bit if you are using MSVC++ compiler

After installation of the above binary, copy the above three dll's in the the directory containing your binary file.

Solution 2

I recommend this source for OpenSSL Windows binaries. These binaries have no external dependencies and tested with 32-bit and 64-bit Qt5.

Update: OpenSSL 1.0 and 1.1 are not binary- and API-compatible. As of Qt 5.12 (certainly 5.12.4) version 1.1 seems the default OpenSSL backend in Qt, although I hear it can be configured to keep using 1.0. I'm testing this source for Windows OpenSSL 1.1 builds, no problems so far: https://bintray.com/vszakats/generic/openssl

I tried everything mentioned in this Question

but nothing worked. The binary works fine on Windows 64-bit, but almost always shows the error
```
Error Creating SSL Context()
```
on Windows 32-bit. I tried the demo http client example.

I have the same problem. By copying those files in the .exe directory, it works for a 32bits application but not for a 64bits one. How to solve that?

And I don't have libssl32.dll but a libssl.dll which is not in Qt installation folder like the two other files.

@SteveTJS you need to download the dlls from the link provided. The ones provided with qt won't work.

Where do you find libssl32.dll under this link? The other two seem to be there but libssl32.dll is missing.

@DamirPorobic: don't know what's that, I only ever needed the two libraries that are present. In fact, I ran a search across my whole disk C: and there is not a single libssl32.dll found, so it doesn't seem I have any software installed that requires it. libeay32.dll and ssleay32.dll is all Qt Network needs.

Came today to the same conclusion. Had libeay32.dll and ssleay32.dll all over the place and only using those two seems to fix the issue.

I tried this and all other suggestions here and in the other question referred above but nothing... nada... Any other ideas to overcome this?
