crypto: xctr - Add XCTR support Add a generic implementation of XCTR mode as a template. XCTR is a blockcipher mode similar to CTR mode. XCTR uses XORs and little-endian addition rather than big-endian arithmetic which has two advantages: It is slightly faster on little-endian CPUs and it is less likely to be implemented incorrect since integer overflows are not possible on practical input sizes. XCTR is used as a component to implement HCTR2. More information on XCTR mode can be found in the HCTR2 paper: https://eprint.iacr.org/2021/1441.pdf Signed-off-by: Nathan Huckleberry <nhuck@google.com> Reviewed-by: Eric Biggers <ebiggers@google.com> Reviewed-by: Ard Biesheuvel <ardb@kernel.org> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> 2022-05-20 18:14:53 +00:00





























































































































































































module: Convert symbol namespace to string literal Clean up the existing export namespace code along the same lines of commit 33def8498fdd ("treewide: Convert macro and uses of __section(foo) to __section("foo")") and for the same reason, it is not desired for the namespace argument to be a macro expansion itself.
