"Unsupported algorithm" error message means that GOST functions was not initialized properly. The question is: how
properly initialize engines with >>statically linked openSSL?
How you init GOST engine with statically linked openSSL?
What next code show you:
//testing loading GOST engine with statically linked openssl library
ENGINE *e;
const char *engine_id = "gost";
ENGINE_load_openssl();
ENGINE_load_builtin_engines();
e = ENGINE_by_id(engine_id);
if(!e)
/* the engine isn't available */
ERR_print_errors(bf_log);
return 1;
if(!ENGINE_init(e)) {
/* the engine couldn't initialise, release 'e' */
ERR_print_errors(bf_log);
ENGINE_free(e);
return 1;
}
//if we here, seems to be initialization is ok
ENGINE_free(e);
ENGINE_cleanup();

Subject: OpenSSL and GOST engine issue (statically linked library )
Hi all !
This is my first mail to openssl mailing list.
I have a problem with statically linked openSSL library and GOST crypto engine.
Openssl 1.0.0g
I have simple client/server application using GOST keys and certificates. It works fine with GOST keys but only if I use
dynamically linked version of openSSL library. If I try to use statically linked openSSL I got an error message.
This is how I initialized openSSL library:
OPENSSL_config("correct config file path");
SSL_library_init();
SSL_load_error_strings();
When I try to read certificate file I got an error.
SSL_CTX_use_certificate_chain_file(ctx, CERTFILE)
Return value here is not 1. So this is an error.
The human readable error message is:
3084809868:error:0609E09C:digital envelope routines:PKEY_SET_TYPE:unsupported algorithm:p_lib.c:239:
3084809868:error:0B07706F:x509 certificate routines:X509_PUBKEY_get:unsupported algorithm:x_pubkey.c:155:
3084809868:error:140BF10C:SSL routines:SSL_SET_CERT:x509 lib:ssl_rsa.c:402:
When I use the same code with dynamically linked openSSL library with external GOST engine library everything works
fine. So what is the difference between static and dynamic version? The only idea that I have at this time that my
library initialization sequence is wrong.
I checked symbols in the compiled libcrypto.a library.
nm ./libcrypto.a | grep gost
This command gave me output with many GOST function which were included to libcrypto.a library. So I think that library
was compiled properly and all GOST engine functions were included in the static library.
"Unsupported algorithm" error message means that GOST functions was not initialized properly. The question is: how
properly initialize engines with statically linked openSSL?
Is it possible to use engines and statically linked openssl library in general?
Best Regards
Xidex
