SSL/TLS and ProVide

From ProVide DocWiki
Jump to: navigation, search

A cipher is an algorithm for performing encryption or decryption - a series of well-defined steps that can be followed as a procedure. 

ProVide supports a large amount of different ciphers, see the bottom of this page for a complete list.


Changing ciphers

In this tutorial we will show you how to change the currently used ciphers, for this example i will be activating TLSv1.2 and deactivating all other ciphers that are activated by default.

- Stop the ProVide Service
- Browse to your ProVide installation directory
- Find and open the settings.ini file with your preferred text editor.
- Search for [FTPS Ciphers]
- Inbetween the quotation marks you can see your currently active ciphers, what we are going to do here is remove everything inside the quotation marks until we are left with "" 
- Now, input the cipher that you wish to use between the quotation marks, in this case i will be using RSA-AES256-SHA256 for TLSv1.2.
- You should now be left with "RSA-AES256-SHA256"
- Start the ProVide service
- You have now successfully activated your new ciphers.


Operating systems

Some operating systems may not have support for certain TLS/SSL ciphers, see the following for an idea of what works and what does not.

Windows Server 2003/XP - SSL 2.0/SSL 3.0/TLS 1.0

Windows Server 2008/Vista - SSL 2.0/SSL 3.0/TLS 1.0

Windows Server 2008 R2/7 - SSL 2.0/SSL 3.0/TLS 1.0/TLS 1.1/TLS 1.2

Windows Server 2012 R2/8.1 - SSL 2.0/SSL 3.0/TLS 1.0/TLS 1.1/TLS 1.2/TLS 1.3

You specify which protocols ProVide should have enabled for FTPS and HTTPS in Settings.ini under the sections "[FTPS Protocols]" and "[HTTPS Protocols]" respectively.

List of supported ciphers

Here is a complete list of ciphers that ProVide supports.

You specify which ciphers ProVide should have enabled for FTPS and HTTPS in Settings.ini under the sections "[FTPS Ciphers]" and "[HTTPS Ciphers]" respectively.
