Cast bitcount to u_in64_t before bit shifting to prevent integer overflow
on 32bit platforms which cause incorrect results when adding a block
>=512M in size. sha1 patch from ante84 at gmail.com via openssh github,
sha2 with djm@, ok tedu@

Wrap blowfish, sha*, md5, and rmd160 so that internal calls go direct

ok deraadt@

Move to the <limits.h> universe.
review by millert, binary checking process with doug, concept with guenther

Use explicit_bzero instead of memset in hash Final and End functions.
OK deraadt@ djm@

calling HashFinal with a null digest should crash, not be silently ignored

Remove landisk gcc 3 compiler workaround. Reminded by martynas@ and brad

Split SHA1Transform() back into smaller pieces when compiling on landisk,
to defeat gcc optimization bugs. Similar to what had been done on sparc64
in the past.
ok millert@ deraadt@

zap remaining rcsid.

Kill old files that are no longer compiled.

okay theo

In the Final function, move the context zeroing into the digest != NULL
scope so that passing a NULL digest is equivalent to the Pad function
(like it used to be). Fixes skey w/ sha1 as noticed by David Krause.

Make the 2nd arg to SHA1Transform const again and unifdef SHA1HANDSOFF.
It was defined before and there is no need to for this knob...

Use KNF indentation style and do some u_char -> u_int8_t conversion
I missed earlier.

Add Pad and FileChunk functions for each family of hash functions.
The Pad function does padding like in Final but does not finish processing.
The FileChunk function creates a digest from a portion of a file.
Also made the length parameters consistent (and size_t).

Make the bit count u_int64_t instead of two u_int32_t. Adapted from
changes Niklas made to the md5 code long ago. OK hshoexer@

Use a common source file for all the hash helper functions that
previously lived in foohl.c. The foohl.c files are now generated
via sed, though perhaps cpp could be used in the future.

Use u_int8_t instead of unsigned char for the buffers struct fooContext.
Add constants for buffer lengths and use them in function prototypes
and the man pages.

This is basically cosmetic surgery; there should be no functional changes.

OK deraadt@

remove sparc64/gcc2 workaround.

ok millert@ deraadt@ jason@

Remove bogus static; from Hiroki Sato

Move the rounds into separate functions on sparc64 so gcc's optimizer
doesn't blow up. This is a hack but is better than compiling sha1.c
with -O0 on sparc64. From NetBSD (mrg).
deraadt@ OK

o Ansi function headers
o Add __BEGIN_DECLS/__END_DECLS to include files
o Safe macros
o Remove useless variable assignment in the End function of *hl.c
o Some minor KNF, needs more
From Dan Weeks

tabify + trailing blanks

Add a missing const

Minor style points.

#include <sha1.h> not #include "sha1.h"

Different sha1 functions (taken from netinet's if_sha1.c) that
are more consistent with md4/md5 functions.

export byte swapping routine.

Moved definitions of BYTE and LONG in from header file.

Fixed standalone test mode for NEW_SHA1.

added sha1 (secure hash function).
