It seems there is no much interest in this change. If so, i guess i'll drop it. |
|
I propose to add a config switch to embed or not raw RSA support in the pkcs11 TA. |
|
Yes. |
|
Sure! |
Add support for CKM_RSA_X_509 mechanism for sing/verify operations. Sign and verify operations are processed using TEE decrypt/encrypt operation since GP TEE Internal Core API specification only allows these modes for TEE_ALG_RSA_NOPAD algorithm. The pkcs11 TA only support sign operation when the provided payload is exactly of the same size as the RSA key used and checks the generate signature is of right size. This mechanism can be needed to support CKM_RSA_X_509 for TLSv1.2 connections. Add CFG_PKCS11_TA_RSA_X_509 to allow configuring the pkcs11 TA with or without raw RSA crypto support. The config switch is default enabled. Signed-off-by: Alexandre Marechal <[email protected]> Signed-off-by: Etienne Carriere <[email protected]> Acked-by: Rouven Czerwinski <[email protected]>

Thanks. Review tag applied. |
Add support for raw RSA operation in the pkcs11 TA.
These changes are mainly driven by the need to support CKM_RSA_X_509 signing operation for devices using PKCS#11 API with some TLSv1.2 connections.
This is somewhat related to old #3701.
