pkey
Publickey Subsystem resource created by ssh2_publickey_init().
algoname
Publickey algorithm (e.g.): ssh-dss, ssh-rsa
blob
Publickey blob as raw binary data
overwrite
If the specified key already exists, should it be overwritten?
attributes
Associative array of attributes to assign to this public key. Refer to ietf-secsh-publickey-subsystem for a list of supported attributes. To mark an attribute as mandatory, precede its name with an asterisk. If the server is unable to support an attribute marked mandatory, it will abort the add process.
