You have to check your libcrypt try this ls -l /usr/lib/libcrypt* If the symbolic links point to libdescrypt*, youre using DES, if it points to libmd5crypt*, youre using MD5. I read that the symbolic link is pointing to libdescrypt* you're useing DES if it points to libmd5crypt* you have MD5 Here is my output ninofision:~$ ls -l /usr/lib/libcrypt* lrwxrwxrwx 1 root wheel 13 Aug 29 03:10 /usr/lib/libcrypt.a -> libdescrypt.a lrwxrwxrwx 1 root wheel 14 Aug 29 03:10 /usr/lib/libcrypt.so -> libdescrypt.so lrwxrwxrwx 1 root wheel 16 Aug 29 03:10 /usr/lib/libcrypt.so.2 -> libdescrypt.so.2 lrwxrwxrwx 1 root wheel 15 Aug 29 03:10 /usr/lib/libcrypt_p.a -> libdescrypt_p.a -r--r--r-- 1 root wheel 1275196 Nov 20 2000 /usr/lib/libcrypto.a lrwxrwxrwx 1 root wheel 14 Aug 29 03:10 /usr/lib/libcrypto.so -> libcrypto.so.1 -r--r--r-- 1 root wheel 782200 Nov 20 2000 /usr/lib/libcrypto.so.1 -r--r--r-- 1 root wheel 1362554 Nov 20 2000 /usr/lib/libcrypto_p.a I guess I'm with DES Gerardo Grant Innes wrote: > Hi Folks, > Following this discussion I've realized I don't know how to determine > whether a password is encrypted with DES or MD5. > Can someone shed some light on how to do this? > > Thanks, > > Grant > > -----Original Message----- > From: owner-freebsd-questions@FreeBSD.ORG > [mailto:owner-freebsd-questions@FreeBSD.ORG]On Behalf Of C J Michaels > Sent: Friday, December 14, 2001 10:41 PM > To: Daniel Leal > Cc: FreeBSD Questions > Subject: RE: encryption and master.passwd > > I believe that it depends upon what library /usr/lib/libcrypt.so is > symlinked to at the time the password is set. > > --Chris > > -----Original Message----- > From: owner-freebsd-questions@FreeBSD.ORG > [mailto:owner-freebsd-questions@FreeBSD.ORG]On Behalf Of Daniel Leal > Sent: Sunday, December 09, 2001 1:50 PM > To: Anthony Atkielski > Cc: freebsd-questions@FreeBSD.ORG > Subject: Re: encryption and master.passwd > > yes, it worked! maybe you are right...
