  For 'while' looping, need stop when 'nbytes == 0', or will cause issue.
  ('nbytes' is size_t which is always bigger or equal than zero).

  The related warning: (with EXTRA_CFLAGS=-W)

  lib/mpi/mpicoder.c:40:2: warning: comparison of unsigned expression >= 0 is always true [-Wtype-limits]

• e10459929   MPILIB: Provide a function to read raw data into an MPI ... Browse Code »

  Provide a function to read raw data of a predetermined size into an MPI rather
  than expecting the size to be encoded within the data. The data is assumed to
  represent an unsigned integer, and the resulting MPI will be positive.

  The function looks like this:

  MPI mpi_read_raw_data(const void *, size_t);

  This is useful for reading ASN.1 integer primitives where the length is encoded
  in the ASN.1 metadata.

  do_encode_md() and mpi_get_keyid() are not parts of mpi library.
  They were used early versions of gnupg and in digsig project,
  but they are not used neither here nor there anymore.

• cdec9cb51   crypto: GnuPG based MPI lib - source files (part 1) ... Browse Code »

  Adds the multi-precision-integer maths library which was originally taken
  from GnuPG and ported to the kernel by (among others) David Howells.
  This version is taken from Fedora kernel 2.6.32-71.14.1.el6.
  The difference is that checkpatch reported errors and warnings have been fixed.

  This library is used to implemenet RSA digital signature verification
  used in IMA/EVM integrity protection subsystem.

  Due to patch size limitation, the patch is divided into 4 parts.
