Even after setting the environment path , the openssl command is not working. Kindly help me for this.
The path of the openssl binary is not
D:\openssl-0.9.8k_X64 as you specified. The openssl binary is inside the
bin subfolder, i.e. the path need to be set as
D:\openssl-0.9.8k_X64\bin. Apart from that please note that openssl 0.9.8 is obsolete for many years and the currently supported version is openssl 1.1.1. I don't know what you are trying to do with openssl but this old version does not support newer TLS versions like TLS 1.2 at all.
