RSA support. This enables the RSA algorithm used for FIT image
|
||
|
|
verification in U-Boot.

See doc/uImage.FIT/signature.txt for more details.

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

algorithm used in FIT image verification. It required RSA Key as

|
input.
