-easy_tls - generic SSL/TLS proxy
-========
-
-(... and example for non-blocking SSL/TLS I/O multiplexing.)
-
-
-  easy_tls.c, easy_tls.h:
-
-     Small generic SSL/TLS proxy library: With a few function calls,
-     an application socket will be replaced by a pipe handled by a
-     separate SSL/TLS proxy process.  This allows easily adding
-     SSL/TLS support to many programs not originally designed for it.
-
-     [Actually easy_tls.c is not a proper library: Customization
-     requires defining preprocessor macros while compiling it.
-     This is quite confusing, so I'll probably change it.]
-
-     These files may be used under the OpenSSL license.
-
-
-
-  test.c, test.h, Makefile, cert.pem, cacerts.pem:
-
-     Rudimentary example program using the easy_tls library, and
-     example key and certificates for it.  Usage examples:
-
-       $ ./test 8443     # create server listening at port 8443
-       $ ./test 127.0.0.1 8443  # create client, connect to port 8443
-                                # at IP address 127.0.0.1
-
-     'test' will not automatically do SSL/TLS, or even read or write
-     data -- it must be told to do so on input lines starting
-     with a command letter.  'W' means write a line, 'R' means
-     read a line, 'C' means close the connection, 'T' means
-     start an SSL/TLS proxy.  E.g. (user input tagged with '*'):
-
-     * R
-       <<< 220 mail.example.net
-     * WSTARTTLS
-       >>> STARTTLS
-     * R
-       <<< 220 Ready to start TLS
-     * T
-       test_process_init(fd = 3, client_p = 1, apparg = (nil))
-       +++ `E:self signed certificate in certificate chain'
-       +++ `<... certificate info ...>'
-     * WHELO localhost
-       >>> HELO localhost
-       R
-       <<< 250 mail.example.net
-
-     You can even do SSL/TLS over SSL/TLS over SSL/TLS ... by using
-     'T' multiple times.  I have no idea why you would want to though.
-
-
-This code is rather old.  When I find time I will update anything that
-should be changed, and improve code comments.  To compile the sample
-program 'test' on platforms other then Linux or Solaris, you will have
-to edit the Makefile.
-
-As noted above, easy_tls.c will be changed to become a library one
-day, which means that future revisions will not be fully compatible to
-the current version.

-librsaref.so is a demonstration dynamic engine that does RSA
-operations using the old RSAref 2.0 implementation.
-
-To make proper use of this engine, you must download RSAref 2.0
-(search the web for rsaref.tar.Z for example) and unpack it in this
-directory, so you'll end up having the subdirectories "install" and
-"source" among others.
-
-To build, do the following:
-
-	make
-
-This will list a number of available targets to choose from.  Most of
-them are architecture-specific.  The exception is "gnu" which is to be
-used on systems where GNU ld and gcc have been installed in such a way
-that gcc uses GNU ld to link together programs and shared libraries.
-
-The make file assumes you use gcc.  To change that, just reassign CC:
-
-	make CC=cc
-
-The result is librsaref.so, which you can copy to any place you wish.

-Precedence: bulk

-
-
-I have been trying to figure out how to produce signatures with EVP_
-routines. I seem to be able to read in private key and sign some
-data ok, but I can't figure out how I am supposed to read in
-public key so that I could verify my signature. I use self signed
-certificate.
-
-I figured I should use
-	EVP_PKEY* pkey = PEM_ASN1_read(d2i_PrivateKey, PEM_STRING_EVP_PKEY,
-	                               fp, NULL, NULL);
-to read in private key and this seems to work Ok.
-
-However when I try analogous
-	EVP_PKEY* pkey = PEM_ASN1_read(d2i_PublicKey, PEM_STRING_X509,
-	                               fp, NULL, NULL);
-the program fails with
-
-error:0D09508D:asn1 encoding routines:D2I_PUBLICKEY:unknown public key type:d2i_pu.c:93
-error:0906700D:PEM routines:PEM_ASN1_read_bio:ASN1 lib:pem_lib.c:232
-
-I figured that the second argument to PEM_ASN1_read should match the
-name in my PEM encoded object, hence PEM_STRING_X509.
-PEM_STRING_EVP_PKEY seems to be somehow magical
-because it matches whatever private key there happens to be. I could
-not find a similar constant to use with getting the certificate, however.
-
-Is my approach of using PEM_ASN1_read correct? What should I pass in
-as name?  Can I use normal (or even self signed) X509 certificate for
-verifying the signature?
-
-When will SSLeay documentation be written ;-)? If I would contribute
-comments to the code, would Eric take time to review them and include
-them in distribution?
-
-I'm using SSLeay-0.6.4. My program is included below along with the
-key and cert that I use.

-What you should do is

-	/* which is the same as PEM_ASN1_read(d2i_X509,PEM_STRING_X509,fp,
-	 * NULL,NULL); */
-Then
-	EVP_PKEY *pkey=X509_extract_key(x509);
-
-There is also a X509_REQ_extract_key(req);
-which gets the public key from a certificate request.
-
-I re-worked quite a bit of this when I cleaned up the dependancy on
-RSA as the private key.
-

-
-:-), PEM_STRING_EVP_PKEY is 'magical' :-).  In theory I should be using a
-standard such as PKCS#8 to store the private key so that the type is 
-encoded in the asn.1 encoding of the object.
-

-
-The actual public key is kept in the certificate, so basically you have 
-to load the certificate and then 'unpack' the public key from the 
-certificate.
-
-> When will SSLeay documentation be written ;-)? If I would contribute
-> comments to the code, would Eric take time to review them and include
-> them in distribution?
-
-:-) After SSLv3 and PKCS#7 :-).  I actually started doing a function list 
-but what I really need to do is do quite a few 'this is how you do xyz' 
-type documents.  I suppose the current method is to post to ssl-users and 
-I'll respond :-).
-
-I'll add a 'demo' directory for the next release, I've appended a

-Scripts for using ECC ciphersuites with test/testssl
-(these ciphersuites are described in the Internet Draft available at
-http://www.ietf.org/internet-drafts/draft-ietf-tls-ecc-03.txt).
-
-Use ECCcertgen.sh, RSAcertgen.sh, ECC-RSAcertgen.sh to generate
-root, client and server certs of the following types:
-
-     ECC certs signed with ECDSA
-     RSA certs signed with RSA
-     ECC certs signed with RSA
-
-Afterwards, you can use ssltest.sh to run the various tests;
-specify one of the following options:
-
-     aecdh, ecdh-ecdsa, ecdhe-ecdsa, ecdh-rsa, ecdhe-rsa
