Description

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

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

It seems 3.55 has the issue but works OK on 3.56.2.
