[openssl-users] Problem using GOST engine with OpenSSL_1_1_0-stable

[Dmitry Belyavsky]

Hello,

I've found a problem when using GOST engine with OpenSSL_1_1_0-stable
The command
openssl s_client -connect tlsgost-256.cryptopro.ru:443
provides the following error report:

139771868619968:error:0306B067:bignum routines:BN_div:div by
zero:crypto/bn/bn_div.c:179:

139771868619968:error:14196112:SSL routines:tls_construct_cke_gost:library
bug:ssl/statem/statem_clnt.c:2436:

The error does not occur when using the master openssl branch.

Thank you!
