Thanks Brad and Mark,
I had configured and used the keys in another application to test the connectivity with my hosting service before attempting to use them in RapidWeaver, so I new the issue was going to be with RapidWeaver.
I had just upgraded to RapidWeaver Version 6.3.7 before attempting to setup ssh keys.
I was expecting things to work as Brad had suggested (configure the public and private key path and provide the private key passphrase), but this did not work…
Unfortunately the solution was to completely remove RapidWeaver and re-install, then re-configure the public and private key settings under SFTP settings of Publishing Settings, all is well now…
If anyone is interested in creating and using SSH Key pairs they can be easily created using ssh-keygen.
Just open Terminal and issue the command: ssh-keygen
Follow the prompts for the default SHA256 2048 bit keys, or: ssh-keygen -b 4096 -C web-hosting
To change the default 2048 bits to 4096 and change the comment from the default firstname.lastname@example.org to “web-hosting”
Hope this helps,
