Encrypted file transfer is the process of encrypting a file before transmitting it over a network, Internet and/or remote server.
It is done to secure a file and hide its content from being viewed or extracted by anyone except the receiver or sender.
Encrypted file transfer is primarily a data security technique used for securing files in transit. Encrypted file transfer works when a file needs to be sent from one device to another, typically over an external network or Internet, which is not secure. The file is encrypted using encryption algorithms, and the file encryption key is shared only with the file sender and recipient. Some of the algorithms used in encrypting files before transfer include data encryption standard (DES) and triple DES.
