C_SetOperationState() public méthode

Restores the cryptographic operations state of a session from bytes obtained with C_GetOperationState
public C_SetOperationState ( uint session, byte operationState, uint operationStateLen, uint encryptionKey, uint authenticationKey ) : CKR
session uint The session's handle
operationState byte Saved session state
operationStateLen uint Length of saved session state
encryptionKey uint Handle to the key which will be used for an ongoing encryption or decryption operation in the restored session or CK_INVALID_HANDLE if not needed
authenticationKey uint Handle to the key which will be used for an ongoing operation in the restored session or CK_INVALID_HANDLE if not needed
