MPILIB: add mpi_read_buf() and mpi_get_size() helpers

2015-06-16T06:35:06Z

Added a mpi_read_buf() helper function to export MPI to a buf provided by the user, and a mpi_get_size() helper, that tells the user how big the buf is. Changed mpi_free to use kzfree instead of kfree because it is used to free crypto keys. Signed-off-by: Tadeusz Struk Signed-off-by: Herbert Xu

crypto: GnuPG based MPI lib - source files (part 1)

2011-11-09T09:45:22Z

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.
