Description
This is a wrapper for PSPXI:EncryptDecryptAes. Before using this PSPXI command, PS module will check whether the algorithm type is AES-CCM. PS module will return error-code 0xC90107E8 when the algorithm type is AES-CCM, since PSPXI:EncryptDecryptAes doesn't support AES-CCM. When the algorithm type is AES-CBC, PS module will clear the low 4-bits of the data size.
