Use custom OpenSSL engine - GOST TLS

[daskain]

How can I use the GOST engine from the custom assembly OpenSSL

OpenSSL works great with this engine, as does curl. But when you try to use in Java - nothing comes out

For example, I declare
System.setProperty ("org.wildfly.openssl.path", "/usr/local/ssl/lib/");
In log:
2020-02-19 14: 19: 52.581 INFO 28673 --- [restartedMain] org.wildfly.openssl.SSL: WFOPENSSL0002 OpenSSL Version OpenSSL 1.1.1d 10 Sep 2019

It's fine, but not work.
when trying to connect to the host, I get an error:

org.springframework.web.client.ResourceAccessException: I/O error on POST request for "https://{host}/api/v1/account/login": 
error:14094410:SSL routines:ssl3_read_bytes:sslv3 alert handshake failure; nested exception is javax.net.ssl.SSLException: 
error:14094410:SSL routines:ssl3_read_bytes:sslv3 alert handshake failure

Block of code with details SSLContext

KeyStore trustedKeyStore = KeyStore.getInstance ("JKS");
trustedKeyStore.load (new FileInputStream ("/home/ubuntu/demo/trustStore"), "truststore" .toCharArray ());

TrustManagerFactory tmf = TrustManagerFactory.getInstance (TrustManagerFactory.getDefaultAlgorithm ());
tmf.init (trustedKeyStore);

SSLContext sslContext = SSLContext.getInstance ("openssl.TLS");
sslContext.init(null, tmf.getTrustManagers(), null);

From the code perspective, you can take a look at this source file.
https://github.com/wildfly-security/wildfly-openssl-natives/blob/main/libwfssl/src/ssl.c

Line 537.

ssl_thread_setup();

/* TODO: engine support? */

So I think this library doesn't support custom engine now.

Could anyone add the support to custom engine ? We also need this feature now.
