Detailed Description

Port Specific File Access functions for PKCS #11.

Function Documentation

PKCS11_PAL_Initialize()

CK_RV PKCS11_PAL_Initialize

(

void

)

Initializes the PKCS #11 PAL.

This is always called first in C_Initialize if the module is not already initialized.

Returns

CKR_OK on success. CKR_FUNCTION_FAILED on failure.

PKCS11_PAL_SaveObject()

CK_OBJECT_HANDLE PKCS11_PAL_SaveObject	(	CK_ATTRIBUTE_PTR	pxLabel,
		CK_BYTE_PTR	pucData,
		CK_ULONG	ulDataSize
	)

Saves an object in non-volatile storage.

Port-specific file write for cryptographic information.

Parameters

[in]	pxLabel	Attribute containing label of the object to be stored.
[in]	pucData	The object data to be saved.
[in]	ulDataSize	Size (in bytes) of object data.

Returns

The object handle if successful. eInvalidHandle = 0 if unsuccessful.

PKCS11_PAL_DestroyObject()

CK_RV PKCS11_PAL_DestroyObject

(

CK_OBJECT_HANDLE

xHandle

)

Delete an object from NVM.

Parameters

[in]

xHandle

Handle to a PKCS #11 object.

PKCS11_PAL_FindObject()

CK_OBJECT_HANDLE PKCS11_PAL_FindObject	(	CK_BYTE_PTR	pxLabel,
		CK_ULONG	usLength
	)

Translates a PKCS #11 label into an object handle.

Port-specific object handle retrieval.

Parameters

[in]	pxLabel	Pointer to the label of the object who's handle should be found.
[in]	usLength	The length of the label, in bytes.

Returns

The object handle if operation was successful. Returns eInvalidHandle if unsuccessful.

PKCS11_PAL_GetObjectValue()

CK_RV PKCS11_PAL_GetObjectValue	(	CK_OBJECT_HANDLE	xHandle,
		CK_BYTE_PTR *	ppucData,
		CK_ULONG_PTR	pulDataSize,
		CK_BBOOL *	pIsPrivate
	)

Gets the value of an object in storage, by handle.

Port-specific file access for cryptographic information.

This call dynamically allocates the buffer which object value data is copied into. PKCS11_PAL_GetObjectValueCleanup() should be called after each use to free the dynamically allocated buffer.

See also

PKCS11_PAL_GetObjectValueCleanup

Parameters

[in]	xHandle	The PKCS #11 object handle of the object to get the value of.
[out]	ppucData	Pointer to buffer for file data.
[out]	pulDataSize	Size (in bytes) of data located in file.
[out]	pIsPrivate	Boolean indicating if value is private (CK_TRUE) or exportable (CK_FALSE)

Returns

CKR_OK if operation was successful. CKR_KEY_HANDLE_INVALID if no such object handle was found, CKR_DEVICE_MEMORY if memory for buffer could not be allocated, CKR_FUNCTION_FAILED for device driver error.

PKCS11_PAL_GetObjectValueCleanup()

void PKCS11_PAL_GetObjectValueCleanup	(	CK_BYTE_PTR	pucData,
		CK_ULONG	ulDataSize
	)

Cleanup after PKCS11_GetObjectValue().

Parameters

[in]	pucData	The buffer to free. (*ppucData from PKCS11_PAL_GetObjectValue())
[in]	ulDataSize	The length of the buffer to free. (*pulDataSize from PKCS11_PAL_GetObjectValue())
