; Certificate/key is needed in server mode and optional in client mode

; Authentication stuff needs to be configured to prevent MITM attacks
; It is not enabled by default!

; Don't forget to c_rehash CApath
;CApath = certs
; It's often easier to use CAfile

; Don't forget to c_rehash CRLpath
;CRLpath = crls
; Alternatively CRLfile can be used
;CRLfile = crls.pem

; Disable support for insecure SSLv2 protocol

; "TIMEOUTclose = 0" is a workaround for a design flaw in Microsoft SSL
; Microsoft implementations do not use SSL close-notify alert and thus
; they are vulnerable to truncation attacks
;TIMEOUTclose = 0
