I am wondering why this is not caught by the tests that try the OAEP encryption. The softhsm should be checking for this since 2014. |

Sigh ... the check is there for encryption, wrapping, unwrapping, but not for decryption ... filled softhsm/SoftHSMv2#671 |
The only supported value is 1UL CKZ_DATA_SPECIFIED

The only supported value for the source field of OAEP params is
1ULorCKZ_DATA_SPECIFIED.Some HSMs(Thales Luna) are strict about enforcing this and reject
0ULas an invalid mechanism.It could be that softhsm2 is more lenient about parsing this parameter.
Addresses #439
Update: indeed softhsm2 does not check this parameter for
CKZ_DATA_SPECIFIEDduring decryption
