Use a slightly unrolled loop, which gets us half way between DES_UNROLL and
no DES_UNROLL. While we're not terribly concerned by DES performance, this
gets us a small gain on aarch64 and a small loss on arm. But above all, we
end up with simpler code.

Fix comment: unsigned int, not just int2025-06-09T17:49:45+00:00tb2025-06-09T17:49:45+00:00urn:sha1:b90fb749f1f69928b571e6d8609b88d660de98a7Move (mostly) MI constants to proper headers2025-06-09T14:37:49+00:00tb2025-06-09T14:37:49+00:00urn:sha1:77890745eac7fbfd51208f10c1759d6998f0692b
Most of the constants here are only defined if a specific header is in
scope. So move the machine-independent macros to those headers and lose
the header guards. Most of these should actually be typedefs but let's
change this when we're bumping the major since this technically has ABI
impact.
IDEA_INT RC2_INT and RC4_INT are always unsigned int
DES_LONG is always unsigned int except on i386
This preserves the existing situation on OpenBSD. If you're using
portable on i386 with a compiler that does not define __i386__,
there's an ABI break.

Rename the header guard of des.h with HEADER_DES_H2025-06-05T06:37:26+00:00tb2025-06-05T06:37:26+00:00urn:sha1:da214f7dcc24dcb9b24028c1aaca17f104cf4496
libdes is dead, Jim. Only its successors continue to haunt us.

Unifdef OPENSSL_SMALL_FOOTPRINT.2025-04-23T10:09:08+00:00jsing2025-04-23T10:09:08+00:00urn:sha1:76042689458cff8aca93ae05da8cfdca7689002f
We do not build with OPENSSL_SMALL_FOOTPRINT and it removes more untested
code paths.

These are all go fast knobs that convolute the code and can be dangerous.
Lets presume that we have a modern and somewhat capable C compiler instead.

There are no assembly implementations now.
