Found the problem...

In puttygen, when you select to create a DSA key, it shows 1024, but creates a key with 1023... We need to clear and put 1024 again to make it create a 1024 key.

Btw, why AndFTP supports only 1024?

10ks anyway

Hello guys! I'm having the same problem with AndFTP to connect in my SFTP server. 1) the server is configured to do not accept passwd authentication, only key-auth. 2) ppk file was created in puttygen, 1024, and exported as openSSH, with password protection 3) the ppk have -----BEGIN DSA PRIVATE KEY...
