Creates a SHA-256 context object.

Synopsis:

#include "husha2.h"

int hu_SHA256Begin(size_t digestLen, sb_YieldCtx yieldCtx, sb_Context *hashContext, sb_GlobalCtx sbCtx)

Since:

BlackBerry 10.0.0

Arguments:

digestLen: The length (in bytes) of a SHA-256 digest. The only acceptable value is SB_SHA256_DIGEST_LEN.

yieldCtx: Ignored.

hashContext: The SHA-256 context object pointer.

sbCtx: A global context.

Library:

libhuapi (For the qcc command, use the -l huapi option to link against this library)

Description:

Note: Yielding is not supported for message digest operations.

Returns:

SB_ERR_BAD_DIGEST_LEN: digestLen is an invalid digest length.

SB_ERR_NULL_CONTEXT_PTR: The hashContext object pointer is NULL.

SB_FAIL_ALLOC: Memory allocation failure.

SB_SUCCESS: Success.
