On entering the following command on centos terminal,
openssl rsa -in smtpd.key -out smtpd.key.unencrypted
I am getting the following error,
Error opening Private Key smtpd.key 3078141676:error:02001002:system library:fopen:No such >file or directory:bss_file.c:398:fopen('smtpd.key','r') 3078141676:error:20074002:BIO >routines:FILE_CTRL:system lib:bss_file.c:400: unable to load Private Key
