Re: How to Enable Weak Ciphers OpenSSL 1.1.1h installation

[Dmitry Belyavsky <beldmit@xxxxxxxxx>]

If you have just built the openssl, try to set the LD_LIBRARY_PATH environment variable pointing to freshly built libcrypto/libssl

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
