d0edffc7da FIPS algorithm blocking.
Non FIPS algorithms are not normally allowed in FIPS mode.

Any attempt to use them via high level functions will return an error.

The low level non-FIPS algorithm functions cannot return errors so they
produce assertion failures. HMAC also has to give an assertion error because
it (erroneously) can't return an error either.

There are exceptions (such as MD5 in TLS and non cryptographic use of
algorithms) and applications can override the blocking and use non FIPS
algorithms anyway.

For low level functions the override is perfomed by prefixing the algorithm
initalization function with "private_" for example private_MD5_Init().

For high level functions an override is performed by setting a flag in
the context.

ec2a595627 Change 'exp' to something else, as 'exp' is predefined by GNU C. This
was already done in HEAD, but not in this branch (I wonder why...).

7e8852c549 Reorder inclusion of header files:
des_old.h redefines crypt:
#define crypt(b,s)\
	DES_crypt((b),(s))

This scheme leads to failure, if header files with the OS's true definition
of crypt() are processed _after_ des_old.h was processed. This is e.g. the
case on HP-UX with unistd.h.
As evp.h now again includes des.h (which includes des_old.h), this problem
only came up after this modification.
Solution: move header files (indirectly) including e_os.h before the header
files (indirectly) including evp.h.

ee60d9fb28 Fix ssl/s3_enc.c, ssl/t1_enc.c and ssl/s3_pkt.c so that we don't

verification error occured.

the legal range.

Dr. Stephen Henson
323f289c48 Change all calls to low level digest routines in the library and
applications to use EVP. Add missing calls to HMAC_cleanup() and
don't assume HMAC_CTX can be copied using memcpy().

Note: this is almost identical to the patch submitted to openssl-dev
by Verdon Walker <VWalker@novell.com> except some redundant
EVP_add_digest_()/EVP_cleanup() calls were removed and some changes
made to avoid compiler warnings.

1876cc32ae This change should be suitable as a workaround for the Solaris x86
compiler bug reported in <01032110293775.22278@weba3.iname.net>
(the '++seq[i]' condition is evaluated as 256 rather than 0
when the previous value is 255).

26a3a48d65 There have been a number of complaints from a number of sources that names
like Malloc, Realloc and especially Free conflict with already existing names
on some operating systems or other packages.  That is reason enough to change
the names of the OpenSSL memory allocation macros to something that has a
better chance of being unique, like prepending them with OPENSSL_.

This change includes all the name changes needed throughout all C files.

413c4f45ed Updates to the new SSL compression code
[Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]

Fix so that the version number in the master secret, when passed
     via RSA, checks that if TLS was proposed, but we roll back to SSLv3
     (because the server will not accept higher), that the version number
     is 0x03,0x01, not 0x03,0x00
