About the function SSL_CTX_use_PrivateKey_file

[Terence Leung]

Dear sir,     I am writing Visual C++ to create secure communication socket.     But when I use the function SSL_CTX_use_PrivateKey_file(),     it always prompt "Enter PEM pass phrase:" to input the pass phrase in the screen.       I want to ask how can I modify the program so that the program can automatically input the pass phrase, no need to input it in the console.       Looking forward to your reply.     Your help will be much appreciated.       Best Regards,     Terence Leung
