Hmm, sort of. That command puts out passwords in SSHA (the algorithm i use) so i got what i wanted, thanks!

But is there to set a different algorithm? Like crypt, md5 etc...?

Sure there is.

% man; is your friend ;) % man slappasswd;

Greetings, some time ago i saw a command (i'm guessing from the ldap-utils package) that would encrypt text into one of the encryptions supported by openldap (md5, crypt etc...) anyone know what that command is?

Thanks!

I bet it's not the same you've seen, anyway I wrote one quick&dirty for me, it creates prompt or read plaintext from stdin, here you go.. One can probably find some other utility to do this..
