C_DecryptFinal

This function operates as specified in PKCS#11.

Although this function will terminate the current encryption operation the session’s decryption state will not be cleared.

Cryptoki specifies that a successful return from one of these functions (when not used for length prediction) should result in the cipher state of that session being reset (to the uninitialized state). ProtectToolkit-C, however, leaves the state initialized so that another operation (using the same key) may be performed without calling the appropriate C_xxxInit function.
