Ports for WIndows NT and Linux exist at http://www.farm9.com Twofish is courtesy of counterpane, and cryptix. We started with the Java version of twofish from cryptix, converted it to C++ (don't ask why), and enhanced it by adding CBC mode and the ciphertext stealing technique from Applied Cryptography (pg. 196). KSSH Added 2001-10-22 KSSH is a simple KDE front-end for Secure Shell (ssh). It calls a terminal where it will execute an ssh call based on user-specified parameters (host, username, port, etc.). SCAIN Added 2001-10-22 SCAIN is a simple cryptographic algorithm that generates different output with the same input and the same password. It uses pass phrases and keys of 128 bits; the idea is to hide the key in the cipher based on the password. aTrans Added 2001-10-22 Easy to move, easy to use, P2P secure file transfer and chat on the windows 32 platform. AES encryption / RSA authentication / Diffie-Hellman EKE, on the fly compression, secure migration in a 400 kb self extracting encrypted package. pwdump3e Added 2001-10-22 PwDump3e provides enhanced protection of the password hash information by encrypting the data before it is passed across the network. It uses Diffie-Hellman key agreement to generate a shared key that is not passed across the network, and employs the Windows Crypto API to protect the hashes. The Crypto API, which is available on Windows 2000 or on NT Service Pack 3 and up, must be present on the the machine where PwDump3e is running, and on the remote machine. The enhanced protection of the hash information effectively prevents network snoopers from obtaining this data. This version should be preferred whenever it is possible to use it. Kerberos: The Network Authentication Protocol Added 2001-10-22 Kerberos is a network authentication protocol. It is designed to provide strong authentication for client/server applications by using secret-key cryptography. A free implementation of this protocol is available from the Massachusetts Institute of Technology. Kerberos is available in many commercial products as well. The Internet is an insecure place. Many of the protocols used in the Internet do not provide any security. Tools to "sniff" passwords off of the network are in common use by systems crackers. Thus, applications which send an unencrypted a password over the network are extremely vulnerable. Worse yet, other client/server applications rely on the client program to be "honest" about the identity of the user who is using it. Other applications rely on the client to restrict its activities to those which it is allowed to do, with no other enforcement by the server. CIPE - Crypto IP Encapsulation Added 2001-10-22 CIPE (Crypto IP Encapsulation) is an ongoing project to build encrypting IP routers. The protocol used is as lightweight as possible. It is designed for passing encrypted packets between prearranged routers in the form of UDP packets. This is not as flexible as IPSEC but it is enough for the original intended purpose: securely connecting subnets over an insecure transit network. MindTerm Added 2001-10-22 MindTerm is a complete ssh-client in pure Java. It can be used either as a standalone Java application or as a Java applet. Three packages of importance are provided (terminal, ssh, and security). The terminal package is a rather complete vt102/xterm-terminal, and the ssh-package contains the ssh- protocol and also "drop-in" socket replacements to use ssh-tunnels transparently from a Java application/applet. It also contains functionality to realize a ssh-server. Finally, the security package contains RSA, DES, 3DES, Blowfish, IDEA, and RC4 ciphers. TapTunnel Added 2001-10-22 TapTunnel is a client and server for creating Ethernet tunnels over TCP/IP-networks (such as the Internet). It can be used to connect two private networks over a public one. It uses raw-ethernet, and therefore can tunnel a variety of protocols (IPX, ARP, IPv4, IPv6, DHCP, etc). psftp Added 2001-10-22 Psftp is basically an ftp-like program that uses ssh 1.x as its backend. Psftp provides a cli ftp-like interface on top of scp and ssh. Browse by category |
