SHA1HashBlock Function

static void SHA1HashBlock(
    BYTE* data, 
    DWORD* h0, 
    DWORD* h1, 
    DWORD* h2, 
    DWORD* h3, 
    DWORD* h4
);

This function calculates the SHA-1 hash sum over a block and updates the values of h0-h3 with the next context.

The data pointer must be WORD aligned on 16-bit parts and DWORD aligned on 32-bit PICs. If alignment is not correct, a memory alignment exception will occur.
