DICT is a dictionary network protocol created by the DICT Development Group in 1997, described by RFC 2229. Its goal is to surpass the Webster protocol to allow clients to access a variety of dictionaries via a uniform interface. In section 3.2 of the DICT protocol RFC, queries and definitions are sent in clear-text, meaning that there is no encryption. Nevertheless, according to section 3.1 of the RFC, various forms of authentication (sans encryption) are supported, including Kerberos version 4. The protocol consists of a few commands a server must recognize so a client can access the available data and lookup word definitions. DICT servers and clients use TCP port 2628 by default. Queries are captured in the following URL scheme: dict:// ; @ : /<c>: : will compile a Unicode-compatible DICT file called mydict, with heading My Dictionary, from mydict.txt which is in Jargon File format i.e.: :word2:definition 2 etc. Once the dictionary file has been produced, it can be easily installed on a server with commands similar to this: mv mydict.dict mydict.index /usr/share/dictd/ /usr/sbin/dictdconfig—write /etc/init.d/dictd restart

dictzip

In order to efficiently store dictionary data, dictzip, an extension to the gzip compression format (also the name of the utility), can be used to compress a .dict file. Dictzip compresses file in chunks and stores the chunk index in the gzip file header, thus allowing random access to the data.
