How I find out what ciphers are supported for an edtFTPj/PRO version?

Question

Hello,

One of our customers is switching to new ciphers and I need to find out whether the current version of edtFTPj/PRO we have supports it.

How do I go about this? Is it documented somewhere which ones are supported?

These are the ciphers I need to check whether they are supported:

ECDHE-RSA-AES256-GCM-SHA384

ECDHE-RSA-CHACHA20-POLY1305-SHA256

We are using versions edtFTPj-PRO-8.2.1.jar and edtFTPj-PRO-7.7.0.jar

Thanks!

The list of TLS/SSL ciphers for FTPS protocol in our edtFTPj/PRO product can be viewed in the User Guide here. Please note that the User Guide online might not be the very latest release, so please check the API documentation included with the product download.

I see one of them mentioned. Is there a way to find out since which version?

Cipher suite.
Name:    TLS_RSA_WITH_AES_256_GCM_SHA384
Authorization:    RSA
Key Exchange:    RSA

Since version 6.0.0..

To confirm ECDHE-RSA-CHACHA20-POLY1305-SHA256 isn't supported?

Not yet. The list in the User Guide (see link above) shows the ciphers which are relevant.
