To make it work for ConnectBot, you need to have a OpenSSH version of this file.
Luckily one can use PuTTYgen to create the OpenSSH key.
Puttygen
In Puttygen, do the following:
- Load the private key: [File] -> [Load Private Key] (*.ppk)
- Enter passphrase if applicable
- Goto: [Conversions] -> [Export OpenSSH key] and save
Android
Now find a way to get this OpenSSH key to your Android like /sdcard folder.
ConnectBot
In ConnectBot, do the following:
- [Menu] -> [Manage Pubkeys]
- [Menu] -> [Import]
- Choose the OpenSSH key from /sdcard
- Click the red lock icon to load the key into memory (lock icon turns green)
- Enter passphrase/password if applicable
- (Disconnect current session)
- Connect!
