Key Exchanged Algorithm Changed

Post by jeisma »

Hi,

Recently the site I've been transferring files to sent a note that they are retiring from their cryptographic library for SFTP the following:

DH_GROUP1_SHA1
DH_GROUP14_SHA1

And that I must switch to

DH_GROUP_EXCHANGE_SHA256
ECDH_NISTP256

What do I need to do on my end to comply? Been exploring Core FTP LE where I can replace a setting with regards to the above, but cannot find any.


TIA!

unless you are using a very old version of Core FTP, you should be fine.

You would not be able to connect if the version you are using does not support DH_GROUP_EXCHANGE_SHA256 which has been in builds since 2014.

There is also always the advanced -> SSH -> use putty compatible SFTP option should you run into any issues.
