Output will be written to the file +"priv_key" unless the \fB\-o\fR option is specified. +.PP +Attributes come in two forms: non\-numerical and numerical. Non\-numerical +attributes are simply any string of letters, digits, and underscores +beginning with a letter. +.PP +Numerical attributes are specified as `attr = N', where N is a non\-negative +integer less than 2^64 and `attr' is another string. The whitespace around +the `=' is optional. One may specify an explicit length of k bits for the +integer by giving `attr = N#k'. Note that any comparisons in a policy given +to cpabe\-enc(1) must then specify the same number of bits, e.g., +`attr > 5#12'. +.PP +The keywords `and', `or', and `of', are reserved for the policy language +of cpabe\-enc (1) and may not be used for either type of attribute. +.PP +Mandatory arguments to long options are mandatory for short options too. +.TP +\fB\-h\fR, \fB\-\-help\fR +print this message +.TP +\fB\-v\fR, \fB\-\-version\fR +print version information +.TP +\fB\-o\fR, \fB\-\-output\fR FILE +write resulting key to FILE +.TP +\fB\-d\fR, \fB\-\-deterministic\fR +use deterministic "random" numbers +(only for debugging) +.PP +Parts Copyright (C) 2006, 2007 John Bethencourt and SRI International. +This is free software released under the GPL, see the source for copying +conditions.
