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
Satyam
