All batch files must be encrypted before the file transfer is initiated using e.g. Pretty Good Privacy (PGP) or similar encryption technology.
Secure FTP (SFTP)¶
Secure FTP is similar to FTP in the previous section with the addition that it is based on encrypted SSH communication. Secure FTP is based on SSH, which is a program for logging into a remote machine and for executing commands on a remote machine. It provides secure encrypted communications between two untrusted hosts over an insecure network.
Worldline requires all batch files to be encrypted before file transfer. Worldline promotes the use of Pretty Good Privacy (PGP) for file encryption.
