This replaces the unwieldy generated implementation of bit-sliced AES in CBC/CTR/XTS modes that originated in the OpenSSL project with a new version that is heavily based on the OpenSSL implementation, but has a number of advantages over the old version: - it does not rely on the scalar AES cipher that also originated in the OpenSSL project and contains redundant lookup tables and key schedule generation routines (which we already have in crypto/aes_generic.) - it uses the same expanded key schedule for encryption and decryption, reducing the size of the per-key data structure by 1696 bytes - it adds an implementation of AES in ECB mode, which can be wrapped by other generic chaining mode implementations - it moves the handling of corner cases that are non critical to performance to the glue layer written in C - it was written directly in assembler rather than generated from a Perl script Signed-off-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
