Hello Everyone,

I have just joined the openssl users community.
My requirement is to have the SSLv3 and weak ciphers enable  with openssl
installation .
I have a query regarding enabling SSLv3 protocol and weak ciphers with
openssl-1.1.1h installation

I have followed the below steps

1)  *./config -enable-weak-ssl-ciphers*


*2) The Makefile looks as below*

*===============================*

if i do any openssl operations it gives error ( core dumped )


      *./openssl ciphers -V*

*       Segmentation fault (core dumped)*


*Can someone help me in resolving this issue ?*


If i don't use option* "**-enable-weak-ssl-ciphers "  *then the above issue
is not seen but SSLv3 and weak ciphers do not get enable.


Thanks
