Generate SSH key for use in Kasm

There are several features in Kasm that accept an SSH key in the RSA format. It is common that a user’s current method of obtaining an SSH key will generate an “OPENSSH” formatted private key instead of an “RSA” (PEM) formatted private key. This article explains how to create a new key or convert an existing key from the OpenSSH format to the RSA format. The correctly formatted key will start with “-----BEGIN RSA PRIVATE KEY-----“ and not “-----BEGIN OPENSSH PRIVATE KEY-----".

Example of the acceptable format:

-----BEGIN RSA PRIVATE KEY----- MIIJKAIBAAKCAgEAzbw8e0aDgfJJsSd9Sw1XmSK9AdtzRDyb4itH1fTMBKbwpSIl rcF9/7d8LGeLMryBO+OQ0ap+3TKbu9fVh8fD7VvleRoC9isRrl+ghVs5LGZ28uTB ... uWBKQE7jqjFCeuXZqLW21toEL5r2TkCbHK035bJD5FTeyzb1pPEHOIhemFE= -----END RSA PRIVATE KEY-----

 

 Instructions

Create a new RSA formatted key:

ssh-keygen -t rsa -b 4096 -m pem -f ./id_rsa

 

Convert an existing OpenSSH formatted key to RSA format:

cp ./id_rsa.openssh ./id_rsa ssh-keygen -p -N "" -m pem -f ./id_rsa
