The Odette File Transfer Protocol (OFTP) is a protocol created in 1986, used for
EDI (Electronic Data Interchange) between two communications business partners. Its name comes from the Odette Organisation (the Organization for data exchange by teletransmission in Europe).
The ODETTE File Transfer Protocol (ODETTE-FTP) was defined in 1986 by working group four of the Organisation for Data Exchange by Tele-Transmission in Europe (ODETTE) to address the electronic data interchange (EDI) requirements of the European automotive industry. It was designed in the spirit of the Open System Interconnection (

OFTP 2 can work
point-to-point or indirectly via a VAN (Value Added Network). A single OFTP 2 entity can make and receive calls, exchanging
files in both directions. This means that OFTP 2 can work in a push or pull mode, as opposed to

OFTP 2 can encrypt
In cryptography, encryption is the process of encoding information. This process converts the original representation of the information, known as plaintext, into an alternative form known as ciphertext. Ideally, only authorized parties can deci ...

In information theory, data compression, source coding, or bit-rate reduction is the process of encoding information using fewer bits than the original representation. Any particular compression is either lossy or lossless. Lossless compressio ...
