FTP Server : Pure-FTPd Over SSL/TLS
2019/11/20
 
Enable SSL/TLS for Pure-FTPd to use secure FTP connections.
[1] Create self-signed certificates.
But if you use valid certificates like from Let's Encrypt or others, you don't need to create this one.
[root@www ~]#
cd /etc/pki/tls/certs

[root@www certs]#
openssl req -x509 -nodes -newkey rsa:2048 -keyout /etc/pki/tls/certs/pure-ftpd.pem -out /etc/pki/tls/certs/pure-ftpd.pem

Generating a 2048 bit RSA private key
.....+++
...................+++
writing new private key to '/etc/pki/tls/certs/pure-ftpd.pem'
-----
You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter '.', the field will be left blank.
