Cannot configure OpenSSL on Windows properly

问题

This question was migrated from Cryptography Stack Exchange because it can be answered on Stack Overflow. Migrated 2 years ago.

I want to use KDSoap, which uses Qt, which uses OpenSSL, to consume a web service, that requires a secure connection, established by using a key stored in a USB HSM (SmartCard + Reader basically, called an Athena IDProtect Key v2.0).

I've installed 64bit OpenSSL from Shining Light Productions. Qt 5.8 can load it (I've checked with QSslSocket).

Problem

The problem is that even though it seems that Qt's network backend should load the OpenSSL config file, it does not. In fact, I think OpenSSL is to blame here and not Qt because of the tests I've done with the provided openssl tool.

First of all, the config is read because any syntax error in the config makes the openssl tool complain about it next time I run it. Second of all, with a clean config, this works:

C:\Users\brokenthorn>openssl engine dynamic -t -pre SO_PATH:C:\OpenSSL-Win64\bin\capi.dll -pre LOAD  -post list_certs
(dynamic) Dynamic engine loading support
[Success]: SO_PATH:C:\OpenSSL-Win64\bin\capi.dll
[Success]: LOAD
Loaded: (capi) CryptoAPI ENGINE
    [ available ]
Certificate 0
<No Friendly Name>
Subject: C = RO, L = Mun. Constanta, O = SC MINI-FARM SRL, CN = Valentina Calin, serialNumber = 2006051670CV93, name = Valentina Calin, GN = Valentina, SN = Calin
Issuer: C = RO, O = certSIGN, OU = certSIGN Qualified CA Class 3 G2, CN = certSIGN Qualified CA Class 3 G2
Certificate 1
<No Friendly Name>
Subject: CN = DESKTOP-IF670KN\\brokenthorn
Issuer: CN = DESKTOP-IF670KN\\brokenthorn
[Success]: list_certs

But if I try to load the engine by ID, after having defined it in the config file, I get an error where it says it cannot find the DLL file, except it adds .dll.dll to the specified ID:

OpenSSL> engine -t -pre ID:capi -pre LOAD
(dynamic) Dynamic engine loading support
[Success]: ID:capi
[Failure]: LOAD
4684:error:25078067:DSO support routines:WIN32_LOAD:could not load the shared library:.\crypto\dso\dso_win32.c:179:filename(capi.dll.dll)
4684:error:25070067:DSO support routines:DSO_load:could not load the shared library:.\crypto\dso\dso_lib.c:233:
4684:error:260B6084:engine routines:DYNAMIC_LOAD:dso not found:.\crypto\engine\eng_dyn.c:467:
    [ unavailable ]

Now, I've tried creating a copy of capi.dll and named it capi.dll.dll and the above command starts working:

OpenSSL> engine -t -pre ID:capi -pre LOAD
(dynamic) Dynamic engine loading support
[Success]: ID:capi
[Success]: LOAD
Loaded: (capi) CryptoAPI ENGINE
    [ available ]

My openssl.cfg is standard except the last part, where've I added the engine directives that should make OpenSSL load the CryptoAPI engine by default, which I need if I'm ever going to be able to open a secure socket using the key stored on the HSM. I'll paste the full config here for a full reference, in case something bad sticks out:

[capi_config]
ID = capi
SO_PATH = C:\OpenSSL-Win64\bin\capi.dll
LIST_ADD = 1
LOAD = 1

Now, OpenSSL should load the capi engine by default on library initialisation, which happens in every app that links with this OpenSSL (and does not call special routines that unload or disable loading of the default config file), including the openssl command line tool.

I don't know how yet, but eventually I should also make it the default crypto provider.

Anyways, after adding the above config and also before that, of course, I get this:

OpenSSL> engine -t
(rdrand) Intel RDRAND engine
    [ available ]
(dynamic) Dynamic engine loading support
    [ unavailable ]

This shouldn't happen. The dynamic engine should have morphed into the capi engine... like the OpenSSL docs say.

Also the CSP for the HSM works. I can list the loaded CSPs like so:

C:\Users\brokenthorn>openssl engine dynamic -t -pre SO_PATH:C:\OpenSSL-Win64\bin\capi.dll -pre LOAD -post list_csps
(dynamic) Dynamic engine loading support
[Success]: SO_PATH:C:\OpenSSL-Win64\bin\capi.dll
[Success]: LOAD
Loaded: (capi) CryptoAPI ENGINE
    [ available ]
Available CSPs:
0. Athena ASECard Crypto CSP, type 1
1. Microsoft Base Cryptographic Provider v1.0, type 1
2. Microsoft Base DSS and Diffie-Hellman Cryptographic Provider, type 13
3. Microsoft Base DSS Cryptographic Provider, type 3
4. Microsoft Base Smart Card Crypto Provider, type 1
5. Microsoft DH SChannel Cryptographic Provider, type 18
6. Microsoft Enhanced Cryptographic Provider v1.0, type 1
7. Microsoft Enhanced DSS and Diffie-Hellman Cryptographic Provider, type 13
8. Microsoft Enhanced RSA and AES Cryptographic Provider, type 24
9. Microsoft RSA SChannel Cryptographic Provider, type 12
10. Microsoft Strong Cryptographic Provider, type 1
11. OpenSC CSP, type 1
[Success]: list_csps

CSP index 0 is my HSM's CSP. I've also sent a few simple commands using the openssl tool, to the HSM, to confirm that it actually works and it does as it should (it's a vendor supplied CSP provider for CAPI).

Any suggestions?
