- * SHA256FinalBits
- *
- * Description:
- *   This function will add in any final bits of the message.
- *
- * Parameters:
- *   context: [in/out]
- *     The SHA context to update.
- *   message_bits: [in]
- *     The final bits of the message, in the upper portion of the
- *     byte.  (Use 0b###00000 instead of 0b00000### to input the
- *     three bits ###.)
- *   length: [in]
- *     The number of bits in message_bits, between 1 and 7.
- *
- * Returns:
- *   sha Error Code.
