These files contain the keys generated with the sshkeygen command, i.e. the keys for authenticating the remote SSH server in PEM format. The keys for all LCOS administrators are stored in a central file. This is accessible to root administrators only, although not for the uploading or downloading of files or certificates.
The ID files have the following structure, which defines the use of a key for a certain LCOS administrator:
*** User xyz
Key
*** End
