We have released Rebex Buru SFTP Server v2.8.0. Here is an overview of changes, fixes and improvements.
New CLI commands for SSH public key management
burusftp user key add -u guybrush -f ed25519.pub -c "definitely guybrush's key" burusftp user key delete -u guybrush -t ed25519 # oops
While using Buru SFTP Server internally, we found that
user update command is quite cumbersome when dealing with public keys.
So we decided to create new lightweight commands to manage the keys - enter
user key add and
user key delete.
Using these commands you can manage users' public keys efficiently, for example remove specific compromised keys across all users.
Web Administration SSH public key management improvements
Prior to version 2.8.0 administrators could only upload public key files. It is now possible to also enter keys directly in the Web Administration. This is especially handy if you keep your keys off the filesystem, for example in a password manager such as 1Password.
Related to the previously mentioned features, you can now assign comments to users' SSH public keys.
This can be done when importing new keys (also using CLI
user key add) or for already registered keys.
SFTP encoding changed to UTF-8
Switching from win-1252 to UTF-8 allows transferring files with non-latin characters without mangling their file names. We believe this change will not cause any issues for our users as encoding of latin characters remains the same but we consider it a breaking change nevertheless.
Safer behavior when removing SSH public keys from users
Prior to version 2.8.0, removing the last SSH key from a user using
user update <username> --remove-keys <key> automatically disabled public key authentication.
With multi-factor authentication this effectively downgraded the credentials needed to password only, which might or might not be what the user wanted.
To avoid any confusion, we now keep the original value for public key authentication (
disabled), no matter whether or not user has any public keys left.
This in effect also means that when the last key is removed and public key authentication is still set to
required, then the user will not be able to log in.
To allow the user to log in, either disable public key authentication (
user update <username> --key-auth disabled) or add a new key to the user using (
user key add).

ecdsanow matches any ECDSA key.
- CLI - user public keys can now be specified directly using

-v <path>) in
path deletecommands is not specified, it defaults to root (
