Techopedia Explains File Transfer Protocol With SSL Security

FTPS is mainly used to provide secure server-to-server communication; however, it can also be used to access a server from desktop or end-user devices.

FTPS uses a combination of symmetric (Data Encryption Standard (DES)/Advance Encryption Standard (AES)) and asymmetric (Rivest-Shamir-Adleman (RSA)/Digital Signature Algorithm (DSA)) algorithms to deliver security and uses X.509 certificates for authentication.

FTPS is delivered in two different forms:

  • Explicit FTPS — Selected parts or components for communication are encrypted.
  • Implicit FTPS — All communications are encrypted.
