Detailed Description

This header file contains definitions, enumerations, structures, and function declarations used for NIST PRF constructions as described in NIST 800-108.

Typedef Documentation

PRFFinalFunc

typedef MSTATUS(* PRFFinalFunc) (MOC_SYM(hwAccelDescr hwAccelCtx) void *ctx, ubyte *result)

Function pointer type for a method that finalizes a PRF context and outputs a result.

nist_prf.h

Parameters

ctx	Pointer to a PRF context that has been previously initialized and updated.
result	Buffer that will hold the resulting output. This can not write more bytes than the output size determined by your PRFOutputSizeFunc.

Returns

Must return OK (0) if successful and non-zero if unsuccessful.

nist_prf.h

PRFOutputSizeFunc

typedef MSTATUS(* PRFOutputSizeFunc) (MOC_SYM(hwAccelDescr hwAccelCtx) void *ctx, ubyte4 *size)

Function pointer type for a method that gets the output size of a Pseudo Random Function (PRF).

nist_prf.h

Parameters

ctx	Pointer to a PRF context.
size	Contents should be set to the output size in bytes of the PRF associated with that context.

Returns

Must return OK (0) if successful and non-zero if unsuccessful.

nist_prf.h

PRFUpdateFunc

typedef MSTATUS(* PRFUpdateFunc) (MOC_SYM(hwAccelDescr hwAccelCtx) void *ctx, const ubyte *data, ubyte4 dataLen)

Function pointer type for a method that updates a PRF context with data.

nist_prf.h

Parameters

ctx	Pointer to a PRF context that has been previously initialized.
data	Buffer holding the input data.
dataLen	The length of the data in bytes.

Returns

Must return OK (0) if successful and non-zero if unsuccessful.
