A_SHAUpdate function

Adds data to a specified hash object.

Syntax


void RSA32API A_SHAUpdate(
  _Inout_ A_SHA_CTX     *Context,
  _Out_   UNSIGNED CHAR *Buffer,
          UNSIGNED INT  BufferSize
);

Parameters

Context [in, out]

The SHA context.

Buffer [out]

The hash table.

BufferSize

The size of the buffer.

Return value

This function does not return a value.

Remarks

This function can be called multiple times to compute the hash on long data streams or discontinuous data streams. The A_SHAFinal function must be called before retrieving the hash value.

This function is very similar to SHAUpdate, but is called directly from the library, rather than being routed through the cryptography infrastructure. For more information, see Windows NTCryptographic Providers.
