COMMON: Fix implicit rejection with RSA keys with empty CKA_PRIVATE_EXPONENT
|
||
|
|
|
||
|
|
An RSA key object that has no CKA_PRIVATE_EXPONENT may either don't have that
|
||
|
|
attribute at all, or may have an empty CKA_PRIVATE_EXPONENT attribute.
|
||
|
|
Both situations should be handed the same, and the private exponent of the
|
||
|
|
key needs to be calculated from the other key components.
|
||
|
|
|
||
|
|
Note that RSA key objects generated with a current soft or ICA token will
|
||
|
|
always have a valid CKA_PRIVATE_EXPONENT attribute, since this is provided
|
||
|
|
during key generation.
