Subject: [PATCH] Bug 1666891 - Add PK11_Pub{Wrap,Unwrap}SymKeyWithMechanism
|
||||
r=mt,rrelyea Summary
|
||||
|
||||
This is useful for RSA-OAEP support.
|
||||
|
||||
The CKM_RSA_PKCS_OAEP mechanism requires a CK_RSA_PKCS_OAEP_PARAMS
|
||||
be present for PKCS#11 calls. This provides required context for OAEP.
|
||||
However, PK11_PubWrapSymKey lacks a way of providing this context and
|
||||
historically silently converted CKM_RSA_PKCS_OAEP to CKM_RSA_PKCS when
|
||||
a RSA key is provided. Introducing a new call will let us indicate
|
||||
parameters and potentially support other mechanisms in the future.
|
||||
This call mirrors the earlier calls introduced for RSA-PSS:
|
||||
PK11_SignWithMechanism and PK11_VerifyWithMechanism.
|
||||
|
||||
The CKM_RSA_PKCS_OAEP mechanism requires a CK_RSA_PKCS_OAEP_PARAMS
|
||||
be present for PKCS#11 calls. This provides required context for OAEP.
|
||||
However, PK11_PubUnwrapSymKey lacks a way of providing this context,
|
||||
and additionally lacked a way of indicating which mechanism type to use
|
||||
for the unwrap operation (instead detecting it by key type). Introducing
|
||||
a new call will let us indicate parameters and potentially support other
|
||||
mechanisms in the future.
