lib/mpi: Introduce ec implementation to MPI library

2020-09-25T07:48:54+00:00

The implementation of EC is introduced from libgcrypt as the basic algorithm of elliptic curve, which can be more perfectly integrated with MPI implementation. Some other algorithms will be developed based on mpi ecc, such as SM2. Signed-off-by: Tianjia Zhang Tested-by: Xufeng Zhang Signed-off-by: Herbert Xu

lib/mpi: Extend the MPI library

2020-09-25T07:48:53+00:00

Expand the mpi library based on libgcrypt, and the ECC algorithm of mpi based on libgcrypt requires these functions. Some other algorithms will be developed based on mpi ecc, such as SM2. Signed-off-by: Tianjia Zhang Tested-by: Xufeng Zhang Signed-off-by: Herbert Xu

lib/mpi: Add mpi_sub_ui()

2020-07-31T08:08:59+00:00

Add mpi_sub_ui() based on Gnu MP mpz_sub_ui() function from file mpz/aors_ui.h[1] from change id 510b83519d1c adapting the code to the kernel's data structures, helper functions and coding style and also removing the defines used to produce mpz_sub_ui() and mpz_add_ui() from the same code.

treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 26

2019-05-24T15:27:10+00:00

Based on 1 normalized pattern(s): gnupg is free software you can redistribute it and or modify it under the terms of the gnu general public license as published by the free software foundation either version 2 of the license or at your option any later version gnupg is distributed in the hope that it will be useful but without any warranty without even the implied warranty of merchantability or fitness for a particular purpose see the gnu general public license for more details you should have received a copy of the gnu general public license along with this program if not write to the free software foundation inc 59 temple place suite 330 boston ma 02111 1307 usa note this code is heavily based on the gnu mp library actually it s the same code with only minor changes in the way the data is stored this is to support the abstraction of an optional secure memory allocation which may be used to avoid revealing of sensitive data due to paging etc the gnu mp library itself is published under the lgpl however i decided to publish this code under the plain gpl extracted by the scancode license scanner the SPDX license identifier GPL-2.0-or-later has been chosen to replace the boilerplate/reference in 14 file(s).

lib/mpi: headers cleanup

2018-06-08T00:34:39+00:00

MPI headers contain definitions for huge number of non-existing functions. Most part of these functions was removed in 2012 by Dmitry Kasatkin - 7cf4206a99d1 ("Remove unused code from MPI library") - 9e235dcaf4f6 ("Revert "crypto: GnuPG based MPI lib - additional ...") - bc95eeadf5c6 ("lib/mpi: removed unused functions") however headers wwere not updated properly. Also I deleted some unused macros.

crypto: rsa - Generate fixed-length output

2016-07-01T15:45:18+00:00

Every implementation of RSA that we have naturally generates output with leading zeroes. The one and only user of RSA, pkcs1pad wants to have those leading zeroes in place, in fact because they are currently absent it has to write those zeroes itself. So we shouldn't be stripping leading zeroes in the first place. In fact this patch makes rsa-generic produce output with fixed length so that pkcs1pad does not need to do any extra work. This patch also changes DH to use the new interface. Signed-off-by: Herbert Xu

lib/mpi: purge mpi_set_buffer()
