Ben Laurie 2ee798880a Add and use a constant-time memcmp. 
This change adds CRYPTO_memcmp, which compares two vectors of bytes in
an amount of time that's independent of their contents. It also changes
several MAC compares in the code to use this over the standard memcmp,
which may leak information about the size of a matching prefix.

Ben Laurie b3f3407850 Use new common flags and fix resulting warnings. 2009-02-15 14:08:51 +00:00
Bodo Möller d8e8fc4803 Put back a variable deleted by the previous revision, 
but used in the code.

Richard Levitte c7ba21493a Hopefully resolve signed vs unsigned issue. 2009-01-28 07:09:23 +00:00
Dr. Stephen Henson d7ecd42255 Fix warnings properly this time ;-) 2009-01-11 20:34:23 +00:00
Dr. Stephen Henson 211655fcdd Fix sign-compare warnings. 2009-01-11 15:58:51 +00:00
Ben Laurie 0eab41fb78 If we're going to return errors (no matter how stupid), then we should 
test for them!
 2008-12-29 16:11:58 +00:00
Dr. Stephen Henson b948e2c59e Update ssl library to support EVP_PKEY MAC API. Include generic MAC support. 2007-06-04 17:04:40 +00:00
Richard Levitte 5fdf06666c Avoid including cryptlib.h, it's not really needed. 
Check if IDEA is being built or not.
This is part of a large change submitted by Markus Friedl <markus@openbsd.org>

Ben Laurie 54a656ef08 Security fixes brought forward from 0.9.7. 2002-11-13 15:43:43 +00:00
Bodo Möller cf82191d77 Implement msg_callback for SSL 2.0. 
Important SSL 2.0 bugfixes (bugs found while implementing msg_callback).
 2001-11-10 01:16:28 +00:00
Bodo Möller ee60d9fb28 Fix ssl/s3_enc.c, ssl/t1_enc.c and ssl/s3_pkt.c so that we don't 
reveal whether illegal block cipher padding was found or a MAC
verification error occured.

In ssl/s2_pkt.c, verify that the purported number of padding bytes is in
the legal range.

Bodo Möller e34cfcf7e1 Consistently use 'void *' for SSL read, peek and write functions. 2001-03-09 10:09:20 +00:00
Richard Levitte bc36ee6227 Use new-style system-id macros everywhere possible. I hope I haven't 
missed any.

This compiles and runs on Linux, and external applications have no
problems with it.  The definite test will be to build this on VMS.

Ulf Möller aa82db4fb4 Add missing #ifndefs that caused missing symbols when building libssl 
as a shared library without RSA.  Use #ifndef NO_SSL2 instead of
NO_RSA in ssl/s2*.c.
