| 4 | To demonstrate how to use ABAC's api in C |

|---|
| 6 | call: attr_abac IceCream_ID.pem IceCream_private.pem IceCream_attr.der |
|---|
| 7 | |
|---|
| 8 | pre-condition: generate IceCream_ID.pem and IceCream_private.pem with |
|---|
| 9 | creddy --generate --cn IceCream |
|---|
| 10 | generate Chocolate_ID.pem and Chocolate_private.pem with |
|---|
| 11 | creddy --generate --cn IceCream |
|---|
| 12 | |
|---|
| 13 | This program will generate an attribute rule, write it out to an external |
|---|
| 14 | file and also load it into the context (prolog db) |
|---|
| 15 | [keyid:IceCream].delicious <- [Keyid:Chocolate] |
|---|
| 16 | |
|---|
| 17 | Then, a query is made against the context to see if it is populated correctly. |
