Middleman has a new name!
by John A. Perry 17 Dec '03

17 Dec '03

It has been brought to my attention that the name "middleman" is too long for the DOS-based remailer programs. In lieu of this I'm changing the listed name middleman(a)jpunix.com to middle(a)jpunix.com. The change will be effective for both the type-I and type-II remailers. I will also make this change to the type2.list/pubring.mix files shortly. The remailers will continue to also answer to middleman(a)jpunix.com.

In a message dated 96-08-21 20:43:50 EDT, you write: >The point is that if you took two novels by the same author and >completely sorted them alphabetically they'd be almost the same. The examples cited did this by word, not by message as your stating. >So a block of PGP encrypted ascii-armored (i.e. 8=>7-bit encoding) >wouldn't affect the frequency counts? Tell me, how long have you been on >your current medications? I was talking about the algorithm as given, not PGP. > That's the point!! IT'S A JOKE!!! You know, "hahaha - very funny"? Not a > serious proposal? I know! But at least it is relevent to the group! How many points of attack have you seen on here? How many techniques have shown up here? P.S. My apologies to the fella I called a troll. It was uncalled for - lacking in social skills.

8-23-96. FiTi: "The race is on for global groups to develop 'electronic purses' using smart cards." "We are moving into the electronic age where money will just be information about the wealth you have," says Visa. Some companies believe that parts of the body, rather than paper or coins, can be used to establish the amount of money somebody has available to spend. WaPo: "Group Plans Challenge To Net Address Monopoly." The end may be at hand for the virtual monopoly that Network Solutions holds over the registration of Internet addresses. The Internet Assigned Numbers Authority, the Internet Society and IETF will organize a competition for the right to operate new registries. The group's aim is to create alternatives to the established categories of Internet addresses. NYP: "Flaw Said to Be Found in Microsoft's Browser."

The demo is for bank checks. The order form has you sending your bank information (including bank number and check info) in the clear. So the hooks into your credit card are not sent in the clear, but the ones to your bank are... Double plus ungood. It is a start...

ctcp.0.9

-----BEGIN PGP SIGNED MESSAGE----- This is a program i found on unimi that offers secure socket connections, utilitizing a simple server/client. It can be installed without root priveledges and uses d/h for key transfers. Anyone looked this package over, and if so what is your oppinion about it? Included below is the THEORY file that describes the key exchange: The encryption negotiation is performed using a protocol similar to FTP/SMTP/NNTP. The client sends commands to the server and the server returns a four-digit response code. Unless stated otherwise, all numbers in this document are hexadecimal with the most significant byte first. When a connection is initiated, the server should send a 2000 response indicating that it is ready to accept commands. Commands: DH3DES - Diffie-Hellman Key exchange followed by Triple-DES encryption If supported, 3001 is returned. The following commands are then expected: MOD - If an argument is supplied, it is the number, in hexadecimal, to use as the modulus. Responses: 2210 - okay 4031 - invalid number 4032 - too small 4033 - too large If no argument is given, the server should supply the modulus, sending 2211 followed by the modulus. If the server is unable to supply a modulus, 4034 should be returned. GEN - this should follow MOD. The generator to use. The format is the same as that of the MOD command. The response codes are 2210, 2211, 4031 or 4034 EXCH - Key exchange Client sends exch followed by gen raised to hir secret exponent. Server sends 4030 if a gen/mod has not been agreed upon. otherwise 2212 followed by gen raised to its exponent ENCR - Begin encrypted Session 4020 - No key selected for encryption 2300 - Encrypted session begin LPORT xxxx - this command takes a 16-bit hexadecimal port number argument, and connects to the specified TCP port on the local host. Responses: 2400 - connected 4010 - Unable to connect 4011 - Access denied RPORT xxxxxxxxxxxx - Connect to remote port The argument to this command is a 48-bit hexadecimal number representing the IP address and port number to connect to. The response should be first 2500, then when the connection has been attempted: 2400 - connected 4010 - Unable to connect 4011 - Access denied QUIT - quit Response: 2100 - Goodbye Summary of error codes: 1xxx - informational messages 10xx - server is supplying additional information that the client may ignore. 11xx - server is responding to a client's request for information 2xxx - okay 20xx - Server is ready 21xx - Disconnect, goodbye 22xx - Command okay 23xx - Encrypted session begins now 24xx - Session with another service begins now 25xx - Command ok, operation in progress, please wait 3xxx - ok so far, send the rest 4xxx - command was okay but could not be processed 5xxx - command not understood or not implemented Triple-DES The triple DES encryption uses output feedback exclusive-ored with a non-sequential counter. There are three counters, each of which is exclusive-ored with the data block before encryption with the corresponding key. The counters are incremented in each round by a shared, secret value which is part of the total key. The result of each round of encryption is exclusive-ored with the data stream.
