The public key file need to be copied to the remote .ssh folder, under the name authorized_keys, where has the private key file id_dsa should be in your Mac .ssh folder.

CertificatesSSL communications are authenticated with the help of certificates for Internet applications such as Mail and Safari. The first time your computer is communicating with a third party, it receives a certificate that will prove its authenticity. Usually, the process consists in accepting the certificate for further communications so that the computer will automatically check the authenticity of the third party compared to its previous sent certificate. This protects the computing from fishing attack. When an unknown certificate is received, such a window appears:


Then to install the certificate for ever, do the following steps:
  1. Click on Show Certificate
