Public Key Fingerprint

Should the SFTP client need to trust a specific server, Slate's SFTP server public key fingerprint is:

ssh-rsa 2048 35:7a:60:48:cf:4f:bc:d1:f1:4e:92:dc:ea:02:18:3b

Command Line SFTP

If the institution is connecting with a command-line SFTP program that takes the connection settings in the form username@server, using a value such as sftp@slate-demo.technolutions.net@ft.technolutions.net may not work correctly. In such cases, replace the first "@" symbol with an equals ("=") symbol, making the resulting setting sftp=slate-demo.technolutions.net@ft.technolutions.net 


  • There is no size limit for SFTP folder content.
