CRYPT(III)                   4/30/73                   CRYPT(III)







NAME

     crypt - password encoding



SYNOPSIS

     mov     $key,r0

     jsr     pc,crypt



     char *crypt(key)

     char *key;



DESCRIPTION

     On  entry,  r0  should  point  to  a  string  of  characters

     terminated  by  an  ASCII  NULL.   The  routine  performs an

     operation on the key which  is  difficult  to  invert  (i.e.

     encrypts  it)  and leaves the resulting eight bytes of ASCII

     alphanumerics in a global cell called ``word''.



     From C, the key argument is a string and the value  returned

     is a pointer to the eight-character encrypted password.



     Login uses this result as a password.
