By default, Limagito File Mover orders algorithms according to best practices, and pays attention to vulnerabilities such as the “Terrapin Attack”.
The following algorithms are supported by Limagito File Mover when our second API Vendor – CK is selected:
Hostkey:
ssh-ed25519
rsa-sha2-256
rsa-sha2-512
ecdsa-sha2-nistp256
ecdsa-sha2-nistp384
ecdsa-sha2-nistp521
ssh-rsa
ssh-dss
Key Exchange:
curve25519-sha256
curve25519-sha256@libssh.org
ecdh-sha2-nistp256
ecdh-sha2-nistp384
ecdh-sha2-nistp521

How to move files to different ftp folders under the same root
How to move files to different ftp folders under the same root on the same server
Q: Conditional destination request. We are looking for an easy way (one channel) to move files to different ftp folders (more than 100 folders) under the same root on the same server, where filename prefix (3 char) is the key to which folder. Prefix and folder name are different.
A few examples:
BBL > folder1
ABB > folder2
BYR > folder4
BYP > folder5
DAT > folder6
I have been looking at your blog post without finding anything like it. The list of prefixes and folders could be a text table in the script or in a csv file. Do you have a script for this?
A: Yes this is possible, please have a look at the following screenshots. This setup can be used with other Sources and Destinations too.
– We used a Windows folder as Source:
– Open our Pascal Script option
Please enable and add the following ‘On Destination’ Pascal Script:
Please add the following script: link
The script strips the first 3 characters from the filename by using ‘copy(psFilename, 1, 3)’
The stripped part is compared with ‘BBL’, ‘ABB’ .. ‘DAT’
Depending on the result of the compare, a folder name is added to our variable psVSA ( pascal script Var String A )
This psVSA variable will be used in the Destination setup as parameter (%VSA, which contains data from psVSA)
You’ll need to adjust the folder names and add more prefixes if needed
– In the FTP as Destination Setup, please adjust the ‘Create Subdir’ option to: %VSA\%SFS
Here we used the %VSA parameter, set in the Pascal Script, which contains the desired subdirectory name
– Feedback customer:
That looks easy. Thank you very much.
If you need any help with this new option, please let us know.

Limagito File Mover mitigates Vulnerability to the SSH Terrapin Attack
The SSH Terrapin Attack
In Limagito File Mover v2024.2.3.0 we made some changes to mitigate the SSH Terrapin attack problem. We did this by modifying the selection of the default algorithms in the following ways:
chacha20-poly1305@openssh.com is no longer included by default. It can be re-added by specifying “+chacha20-poly1305@openssh.com” in the new UncommonOptions property we added.
We kept the “-cbc” encryption modes because potentially too many servers would be affected by eliminating these encryption algorithms.
We no longer include the “-etm” MAC algorithms, which are:
hmac-sha1-etm@openssh.com
hmac-sha2-256-etm@openssh.com
hmac-sha2-512-etm@openssh.com
The -etm MAC algorithms can be re-added by specifying “+ssh-hmac-etm” in the new UncommonOptions property.
For more information about the Terrapin attack, see https://terrapin-attack.com/
In the following example I re-added the -etm MAC algorithms by specifying “+ssh-hmac-etm” in the new “Uncommon Options” property (Advanced Tab).
