In this specific case, how do I call it? MD5 is included in the kernel by default. So just call the same routines shown in the md5(3) man page... they're declared in /sys/crypto/md5.h, which you should #include in your C file(s). > If CHAP uses MD5, how does ng_ppp or kernel ppp handle this (or does > it)? In the ng_ppp case, in user-land where all PPP negotiation takes place. For kernel PPP, in the kernel -- see sys/net/if_spppsubr.c. -Archie ___________________________________________________________________________ Archie Cobbs * Whistle Communications, Inc. * http://www.whistle.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
