crypto/aes/README

-This is an OpenSSL-compatible version of AES (also called Rijndael).
-aes_core.c is basically the same as rijndael-alg-fst.c but with an
-API that looks like the rest of the OpenSSL symmetric cipher suite.

crypto/bf/README

-This is a quick packaging up of my blowfish code into a library.
-It has been lifted from SSLeay.
-The copyright notices seem a little harsh because I have not spent the
-time to rewrite the conditions from the normal SSLeay ones.
-
-Basically if you just want to play with the library, not a problem.

crypto/conf/README

-Configuration modules. These are a set of modules which can perform
-various configuration functions.
-
-Currently the routines should be called at most once when an application
-starts up: that is before it starts any threads.
-
-The routines read a configuration file set up like this:
-
------
-#default section
-openssl_conf=init_section
-
-[init_section]
-
-module1=value1
-#Second instance of module1
-module1.1=valueX
-module2=value2
-module3=dso_literal
-module4=dso_section
-
-[dso_section]
-
-path=/some/path/to/some/dso.so
-other_stuff=other_value
-----
-
-When this file is loaded a configuration module with the specified string
-(module* in the above example) is looked up and its init function called as:
-
-int conf_init_func(CONF_IMODULE *md, CONF *cnf);
-
-The function can then take whatever action is appropriate, for example further
-lookups based on the value. Multiple instances of the same config module can be
-loaded.
-
-When the application closes down the modules are cleaned up by calling an
-optional finish function:
-
-void conf_finish_func(CONF_IMODULE *md);
-
-The finish functions are called in reverse order: that is the last module
-loaded is the first one cleaned up.
-
-If no module exists with a given name then an attempt is made to load a DSO
-with the supplied name. This might mean that "module3" attempts to load a DSO
-called libmodule3.so or module3.dll for example. An explicit DSO name can be
-given by including a separate section as in the module4 example above.
-
-The DSO is expected to at least contain an initialization function:
-
-int OPENSSL_init(CONF_IMODULE *md, CONF *cnf);
-
-and may also include a finish function:
-
-void OPENSSL_finish(CONF_IMODULE *md);
-
-Static modules can also be added using,
-
-int CONF_module_add(char *name, dso_mod_init_func *ifunc, dso_mod_finish_func
-*ffunc);
-
-where "name" is the name in the configuration file this function corresponds
-to.
-
-A set of builtin modules (currently only an ASN1 non functional test module)
-can be added by calling OPENSSL_load_builtin_modules(). 
-
-The function OPENSSL_config() is intended as a simple configuration function
-that any application can call to perform various default configuration tasks.
-It uses the file openssl.cnf in the usual locations.

-The primary ftp site for this library is
-ftp://ftp.psy.uq.oz.au/pub/Crypto/DES/libdes-x.xx.tar.gz
-libdes is now also shipped with SSLeay.  Primary ftp site of
-ftp://ftp.psy.uq.oz.au/pub/Crypto/SSL/SSLeay-x.x.x.tar.gz
-
-The best way to build this library is to build it as part of SSLeay.
-
-This kit builds a DES encryption library and a DES encryption program.
-It supports ecb, cbc, ofb, cfb, triple ecb, triple cbc, triple ofb,
-triple cfb, desx, and MIT's pcbc encryption modes and also has a fast
-implementation of crypt(3).
-It contains support routines to read keys from a terminal,
-generate a random key, generate a key from an arbitrary length string,
-read/write encrypted data from/to a file descriptor.
-
-The implementation was written so as to conform with the manual entry
-for the des_crypt(3) library routines from MIT's project Athena.
-
-destest should be run after compilation to test the des routines.
-rpw should be run after compilation to test the read password routines.
-The des program is a replacement for the sun des command.  I believe it
-conforms to the sun version.
-
-The Imakefile is setup for use in the kerberos distribution.
-
-These routines are best compiled with gcc or any other good
-optimising compiler.
-Just turn you optimiser up to the highest settings and run destest
-after the build to make sure everything works.
-
-I believe these routines are close to the fastest and most portable DES
-routines that use small lookup tables (4.5k) that are publicly available.
-The fcrypt routine is faster than ufc's fcrypt (when compiling with
-gcc2 -O2) on the sparc 2 (1410 vs 1270) but is not so good on other machines
-(on a sun3/260 168 vs 336).  It is a function of CPU on chip cache size.
-[ 10-Jan-97 and a function of an incorrect speed testing program in
-  ufc which gave much better test figures that reality ].
-
-It is worth noting that on sparc and Alpha CPUs, performance of the DES
-library can vary by upto %10 due to the positioning of files after application
-linkage.

crypto/dsa/README

-The stuff in here is based on patches supplied to me by
-Steven Schoch <schoch@sheba.arc.nasa.gov> to do DSS.
-I have since modified a them a little but a debt of gratitude
-is due for doing the initial work.

crypto/ripemd/README

-RIPEMD-160
-http://www.esat.kuleuven.ac.be/~bosselae/ripemd160.html
-
-This is my implementation of RIPEMD-160.  The pentium assember is a little
-off the pace since I only get 1050 cycles, while the best is 1013.
-I have a few ideas for how to get another 20 or so cycles, but at
-this point I will not bother right now.  I believe the trick will be
-to remove my 'copy X array onto stack' until inside the RIP1() finctions the
-first time round.  To do this I need another register and will only have one
-temporary one.  A bit tricky....  I can also cleanup the saving of the 5 words
-after the first half of the calculation.  I should read the original
-value, add then write.  Currently I just save the new and read the origioal.
-I then read both at the end.  Bad.

crypto/threads/README

-Mutithreading testing area.
-
-Since this stuff is very very platorm specific, this is not part of the
-normal build.  Have a read of doc/threads.doc.
-
-mttest will do some testing and will currently build under Windows NT/95,
-Solaris and Linux.  The IRIX stuff is not finished.
-
-I have tested this program on a 12 CPU ultra sparc box (solaris 2.5.1)
-and things seem to work ok.
-
-The Linux pthreads package can be retrieved from
