* Very big makeover in the way telnet, telnetd and libtelnet are built.Mark Murray2003-07-1621-6451/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | Previously, there were two copies of telnet; a non-crypto version that lived in the usual places, and a crypto version that lived in crypto/telnet/. The latter was built in a broken manner somewhat akin to other "contribified" sources. This meant that there were 4 telnets competing with each other at build time - KerberosIV, Kerberos5, plain-old-secure and base. KerberosIV is no longer in the running, but the other three took it in turns to jump all over each other during a "make buildworld". As the crypto issue has been clarified, and crypto _calls_ are not a problem, crypto/telnet has been repo-copied to contrib/telnet, and with this commit, all telnets are now "contribified". The contrib path was chosen to not destroy history in the repository, and differs from other contrib/ entries in that it may be worked on as "normal" BSD code. There is no dangerous crypto in these sources, only a very weak system less strong than enigma(1). Kerberos5 telnet and Secure telnet are now selected by using the usual macros in /etc/make.conf, and the build process is unsurprising and less treacherous. Notes: svn path=/head/; revision=117675

* Background:Jacques Vidrine2003-01-292-14/+2
| | | | | | | | | | | | | | | | | | | | | | | | When libdes was replaced with OpenSSL's libcrypto, there were a few interfaces that the former implemented but the latter did not. Because some software in the base system still depended upon these interfaces, we simply included them in our libcrypto (rnd_keys.c). Now, finally get around to removing the dependencies on these interfaces. There were basically two cases: des_new_random_key -- This is just a wrapper for des_random_key, and these calls were replaced. des_init_random_number_generator et. al. -- A few functions were used by the application to seed libdes's PRNG. These are not necessary when using libcrypto, as OpenSSL internally seeds the PRNG from /dev/random. These calls were simply removed. Again, some of the Kerberos 4 files have been taken off the vendor branch. I do not expect there to be future imports of KTH Kerberos 4. Notes: svn path=/head/; revision=110049

* Add SRA authentication to src/crypto/telnet.Nick Sayer1999-08-169-4/+840
| | | | | | | | | | | | | | | | | | | | | | | SRA does a Diffie-Hellmen exchange and then DES-encrypts the authentication data. If the authentication is successful, it also sets up a session key for DES encryption. SRA was originally developed at Texas A&M University. This code is probably export restricted (despite the fact that I originally found it at a University in Germany). SRA is not perfect. It is vulnerable to monkey-in-the-middle attacks and does not use tremendously large DH constants (and thus an individual exchange probably could be factored in a few days on modern CPU horsepower). It does not, however, require any changes in user or administrative behavior and foils session hijacking and sniffing. The goal of this commit is that telnet and telnetd end up in the DES distribution and that therefore an encrypted session telnet becomes standard issue for FreeBSD.
