It supports fully configurable ANSI menus, multiple languages, IEMSI, standard file transfer protocols, and native Linux doors. The mailer supports the FTS-0001, YooHoo/2U2, EMSI protocols over modem, and the TCP/IP Binkp and IFC protocols, Zedzap, Zmodem, Telink, and Hydra file transfer protocols. Full FTN mail support, including automatic routing for hub and host systems, is included. A Fidonet/Internet gateway is also built-in. The internal mail format is JAM (c) messagebase, and there is full tic file support, including extended tic files.
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.
