What is OFTP?
OFTP stands for Odette File Transfer Protocol and is used for EDI communication in the European automotive industry. Odette was an EDI standard created for this industry and OFTP is the corresponding connection protocol that was created to support this functionality.
OFTP works similar to regular FTP with file transfer delivery/retrieval, but with added layers of security and message encryption. OFTP depends on each party’s SSID and SFID to be exchanged that will be used during communication to facilitate encryption and compression. The SSID (Start Session ID) tells the OFTP server who the connecting party is and allows the server to grant them access. After that, the SFIF (Start File ID) that contains information useful to the file they are about to send including encryption and compression.
