Hi, In version 3.55.0, FileZilla Client on Mac throws error "Could not get reply from fputtygen" when it is trying to import an RSA key to generate the PPK formatted key. In older version, it is successfully importing the key and converting them to PPK format without this error. We are using FileZilla Pro.

Steps:

1. Generate an RSA key using command "ssh-keygen -t rsa -b 4096 -C "filezillaPPKconversionissue" -f temp"
2. For password, provide any password like 'test'
3. Open FileZilla 3.55.0 > File > Site Manager
4. Protocol: SFTP
5. host: enter host
6. Logon type: Key file
7. User: enter user
8. Key file: select the private key generated "temp"
9. FileZilla client will prompt to convert key to pPK format. click yes

10 enter key password and confirm

11. enter filename for PPK file like 'testppk' and press SAVE in the file save dialog
12. you will get error popup "Could not get reply from fputtygen"

Latest Putty Key Gen tool, 0.75 and up, now use the ARGON2 Key derivation type for the private key and Filezilla client won't allow you to even select this key for use.

0.76 has the same so I believe this is the new Putty format going forward. Since Filezilla and Putty key gen are most commonly used together, I would like to see Filezilla support this format.

The download of FileZilla for Windows in the front page is infected with malware:
