CAKE (Key Addressed Crypto Encapsulation) is a bunch of Python and C++ for implementing the CAKE protocol. The CAKE protocol is a protocol in which all messages have source and destination addresses that are public keys. This is in the same way that IP packets have a source and destination address that is an IP address.
MSNgrep is a script to capture MSN Messenger conversations. It uses pylibpcap to sort through MSN's jumble of packets for instant messages, a few status messages, and TypingUser notifications. Using these, it builds up a database of email addresses to MSN server addresses, and local IP addresses. This lets it match up an instant message to the sender's email address, and the receiver's email address.
The ipoque PRX traffic manager effectively detects and controls all major peer-to-peer (P2P) filesharing, instant messaging (IM), and Voice over IP (VoIP) protocols. Bandwidth and volume limits can be assigned to network links, subnets, individual users, and user groups. Detailed usage statistics are provided and can be exported for post-processing. This community edition is a fully functional version with a bandwidth limit of 2 Mbit/s.
SILC (Secure Internet Live Conferencing) is a protocol which provides secure conferencing services in the Internet. It can be used to send any kind of messages, in addition to normal text messages. This includes multimedia messages like images, video, and audio stream. All messages in the SILC network are encrypted and authenticated, and messages can also be digitally signed. SILC protocol supports AES, SHA-1, PKCS#1, PKCS#3, X.509, OpenPGP, and is being developed in the IETF. The software is delivered as SILC Client for end users, SILC Server for system administrators, and SILC Toolkit for application developers.
alph implements and analyzes historical and traditional ciphers and codes, such as polyalphabetic, substitutional, and mixed employing human-reconstructable algorithms. It provides a pipe filter interface in order to encrypt and decrypt block text to achieve transparency. The program is meant to be used in conjunction with external programs that transfer data, resulting in transparent encryption or decryption of information. The program can thus be used as a mail filter, IRC filter, IM filter, and so on.
AIM Sniff is a utility for monitoring and archiving AIM and MSN messages across a network. It can be used to monitor for cases of harassment or warez trading. It has the ability to do a live dump (actively sniff the network) or read a PCAP file and parse the file for IM messages. You also have the option of dumping the information to a MySQL database or STDOUT. AIM Sniff will also monitor for an IM login and then perform an SMB lookup on the originating computer in order to match NT Domain names with IM login names (handles).
