  • d58bb7e55   lib/mpi: Introduce ec implementation to MPI library ... Browse Code »

    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.

    Expand the mpi library based on libgcrypt, and the ECC algorithm of
    mpi based on libgcrypt requires these functions.

    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.

    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

  • cbdc61ae1   lib/mpi: headers cleanup ... Browse Code »

    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.

  • 9b45b7bba   crypto: rsa - Generate fixed-length output ... Browse Code »

    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.

  • 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.

  • 5ce3e312e   crypto: GnuPG based MPI lib - header files (part 2) ... 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.
