How to generate ssh key using puttygen for bamboo 6.4

Question

Hi, I am getting errors when trying to use OpenSSH format pem private key for our v6.4 bamboo to access our atlassian bitbucket repo using ssh key.

We kept getting this error with and without passphrase:

com.atlassian.bamboo.repository.RepositoryException: Cannot decode connection params
	at com.atlassian.bamboo.plugins.git.NativeGitOperationHelper.beforeRepositoryAccess(NativeGitOperationHelper.java:229)
......

Caused by: java.io.IOException: unrecognised object: OPENSSH PRIVATE KEY
	at org.bouncycastle.openssl.PEMParser.readObject(Unknown Source)
	at com.atlassian.bamboo.plugins.ssh.ProxyConnectionDataBuilderImpl.withKeyFromReader(ProxyConnectionDataBuilderImpl.java:88)
......

I assume bamboo can read OpenSSH format according to https://confluence.atlassian.com/bamkb/error-while-opening-ssh-session-when-using-putty-format-keys-608731364.html

Hello @Steve Pranadhita

As you are running Bamboo 6.4, that version will not support the OpenSSH pem format. That is only available on the most recent versions of the product.

Please convert the key to the old PEM format and try again.

$ ssh-keygen -m PEM -t rsa -C user@domain -f ~/.ssh/id_rsa_pem
