• If your key is not an RSA key, you can convert it with the following command:

$ file original.key
original.key: ASCII text

$ openssl rsa -in original.key -out private.key
writing RSA key

$ file private.key
private.key: PEM RSA private key

• Logged in as admin, install the certificate using the following qq command:

qq ssl_modify_certificate

• See example below:

[~/qumulo_api]$ ./qq --host sli-q2 login -u admin
Password:

[~/qumulo_api]$ ./qq --host sli-q2 ssl_modify_certificate -c certbundle.pem -k private.key
null
