9 | The Modular Exponentiation algorithm in RSA is implemented using |
10 | driver model. So CONFIG_DM needs to be enabled by default for this | |
11 | library to function. | |
12 | The signing part is build into mkimage regardless of this | |
13 | option. The software based modular exponentiation is built into | |
14 | mkimage irrespective of this option. | |

21 | Enables driver for modular exponentiation in software. This is a RSA | |
22 | algorithm used in FIT image verification. It required RSA Key as | |
23 | input. | |
