DES and MD5 +hashes are currently supported. When generating a password hash a random +salt is generated and applied. +.PP +A hashed password can be validated by specifying \fI-c\fP or \fI--check\fP and +passing \fIhashed_password\fP after \fIplaintext_password\fP on the command line. +In this case \fIhashed_password\fP will be checked to see if it matches +\fIplaintext_password\fP. If so "Password OK" will be printed and the exit +status will be 1, otherwise "Password BAD" will be printed and exit status +will be 0 (Note this is the opposite of a normal successful shell status). + +.SH OPTIONS + +.IP "\-d --des" +Use a DES (Data Encryption Standard) hash (default). +Ignored if performing a password check. +.IP "\-m --md5" +Use a MD5 (Message Digest 5) hash. +Ignored if performing a password check. +.IP "\-c --check" +Perform a validation check on a password hash to verify if it matches +the plantext password. + +.SH EXAMPLES +.nf +$ radcrypt foobar +HaX0xn7Qy650Q +$ radcrypt \-c foobar HaX0xn7Qy650Q +Password OK +.fi +.SH SEE ALSO +radiusd(8), crypt(3) +.SH AUTHORS +Miquel van Smoorenburg <miquels@cistron-office.nl> |
