Difference between SFTP and ftps

All are encrypted for FTP connections, and the Protocols are very similar. One is encrypted using the SSL protocol, and the other is encrypted using SSH. SSL is designed for encryption such as HTTP and SMTP, and SSH is designed for encryption such as telnet and FTP and the establishment of transmission channels. In fact, ssh establishes a transmission channel for encryption and transmission, and this channel can be used for remote login. If we only talk about their functions, in general, SSH is like laying a pipe. SSL is like packaging, laying a pipe and packing a package will ensure data security. It is a process of making a key, because SSH is a pipe, it is suitable for Secure FTP transmission. In fact, we still need to summarize the principles. To put it simply, the SFTP protocol is an independent protocol in SSH, and data can be transmitted using the SFTP server. Ftps means FTP-over-SSL, that is, FTP uses the SSL protocol to encrypt transmission, not only using the FTP server but also using the SSL protocol to encrypt transmission. (For FTP-over-Ssh, it is completely different from SFTP transmission mode, that is, data transmission is encrypted using the FTP server and SSH protocol. )
