Function Documentation

AES_MMO_allocDigest()

MOC_EXTERN MSTATUS AES_MMO_allocDigest

(

MOC_SYM(hwAccelDescr hwAccelCtx) BulkCtx *

pp_context

)

Allocates a new AES-MMO context. Be sure to call AES_MMO_freeDigest in order to free the memory when done with the context.

Parameters

pp_context

Pointer to the location of the newly allocated context.

Returns

OK (0) if successful, otherwise a negative number error code from merrors.h.

AES_MMO_completeDigest()

MOC_EXTERN MSTATUS AES_MMO_completeDigest	(	MOC_SYM(hwAccelDescr hwAccelCtx) const ubyte *	pData,
		ubyte4	dataLen,
		ubyte *	pHashOutput
	)

Performs the AES-MMO hash in a context free one-shot style.

Parameters

pData	Buffer of data to be digested.
dataLen	The length of the data in bytes.
pHashOutput	Buffer to hold the resulting hash. This must be 16 bytes in length.

Returns

OK (0) if successful, otherwise a negative number error code from merrors.h.

AES_MMO_final()

MOC_EXTERN MSTATUS AES_MMO_final	(	MOC_SYM(hwAccelDescr hwAccelCtx) AES_MMO_CTX *	pAesMmoCtx,
		ubyte *	pHashOutput
	)

Finalizes an AES-MMO context and outputs the resulting hash.

Parameters

pAesMmoCtx	Pointer to a previously initialized and updated context.
pHashOutput	Buffer to hold the resulting hash. This must be 16 bytes in length.

Returns

OK (0) if successful, otherwise a negative number error code from merrors.h.

AES_MMO_freeDigest()

MOC_EXTERN MSTATUS AES_MMO_freeDigest

(

MOC_SYM(hwAccelDescr hwAccelCtx) BulkCtx *

pp_context

)

Deletes a and frees the memory for an AES-MMO context.

Parameters

pp_context

Pointer to the location of the context to be deleted.

Returns

OK (0) if successful, otherwise a negative number error code from merrors.h.

AES_MMO_initDigest()

MOC_EXTERN MSTATUS AES_MMO_initDigest

(

MOC_SYM(hwAccelDescr hwAccelCtx) AES_MMO_CTX *

pAesMmoCtx

)

Initializes an AES-MMO context. This zeroes the context but does not free allocated memory.

Parameters

pAesMmoCtx

Pointer to the context to be initialized.

Returns

OK (0) if successful, otherwise a negative number error code from merrors.h.

AES_MMO_updateDigest()

MOC_EXTERN MSTATUS AES_MMO_updateDigest	(	MOC_SYM(hwAccelDescr hwAccelCtx) AES_MMO_CTX *	pAesMmoCtx,
		const ubyte *	pData,
		ubyte4	dataLen
	)

Updates an AES-MMO context with a buffer of data. This may be called as many times as necessary.

Parameters

pAesMmoCtx	Pointer to a previously initialized context.
pData	Buffer of data to be digested.
dataLen	The length of the data in bytes.

Returns

OK (0) if successful, otherwise a negative number error code from merrors.h.
