Tracker Comment Comment on Cannot putFile or getFile when using key instead of password within FTP service by Aaron N.
2608658 CF-4032599 Aaron N. Hi Adobe,
I've verified this is fixed in CF2016 Update 1 (build 2016.0.01.298513). cfftp works properly and no longer throws "com.jcraft.jsch.JSchException: Algorithm negotiation fail" when using the fingerprint or key attributes.
Thanks!,
-Aaron

comparison. CF11 and CF2016 is using JSch for Secure Channel FTP. CF11 has jsch-0.1.44m.jar and CF2016 has jsch-0.1.52m.jar. I copied the newer version into the lib folder for CF11 and retested with CF11 after restarting. Now, when using CF11 the sFTP connection works. There’s your issue.

2608735 CF-4014234 Hana H. Just wanted to mentioned I used Wil Genovese's solution and SFTP to the site that is using SHA2 is working now. I found a copy of jsch-0.1.52m.jar, copied it over to the coldfusion /lib folder and restarted ColdFusion. Worked like a charm. Thanks Wil

2608735 CF-4014234 Cathy W. Where did you all find this elusive updated jar file? I am not finding it anywhere, although I do see the jsch-0.1.52.jar all over the place.
2608735 CF-4014234 S P. Hi Eric,
As you have specified the JSCH jar library in ColdFusion does not list the HMAC-SHA-256 hashing protocol.
I was trying to verify this issue with FreeSSHD SFTP Server as well as Core SFTP Client server, where I was trying to set it up with the above specified

-support of the S-FTP encryption or hashing protocols by the current JSCH jar library used (which is jsch-0.1.44m.jar). From the class list it does not seem that HMAC-SHA-256 is supported.
The trace from Filezilla Client reveals this protocol:
