# ssh2_publickey_add

(PECL)

ssh2_publickey_add -- Add an authorized publickey

## Beschreibung

bool ssh2_publickey_add ( resource pkey, string algoname, string blob [, bool overwrite [, array attributes]] )

> Anmerkung: The publickey subsystem is used for managing publickeys on a server to which the client is already authenticated. To authenticate to a remote system using publickey authentication, use the ssh2_auth_pubkey_file() function instead.

## Parameter Liste

`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.

## Rückgabewerte

Gibt bei Erfolg `TRUE` zurück, im Fehlerfall `FALSE`.

## Beispiele
