NAME

       libssh2_knownhost_add - add a known host

SYNOPSIS

       #include <libssh2.h>

       int libssh2_knownhost_addc(LIBSSH2_KNOWNHOSTS *hosts,
                                  char *host, char *salt,
                                  char *key, size_t keylen,
                                  const char *comment, size_t commentlen,
                                  int typemask,
                                  struct libssh2_knownhost **store);

DESCRIPTION

       Adds a known host to the collection of known hosts identified by the 'hosts' handle.

       host  is  a pointer the host name in plain text or hashed. If hashed, it must be provided base64 encoded.
       The host name can be the IP numerical address of the host or the full name.

       If you want to add a key for a specific port number for the given host, you must provide  the  host  name
       like  '[host]:port' with the actual characters '[' and ']' enclosing the host name and a colon separating
       the host part from the port number. For example: "[host.example.com]:222".

       salt is a pointer to the salt used for the host hashing, if the host is provided hashed. If the  host  is
       provided  in plain text, salt has no meaning.  The salt has to be provided base64 encoded with a trailing
       zero byte.

       key is a pointer to the key for the given host.

       keylen is the total size in bytes of the key pointed to by the key argument

       comment is a pointer to a comment for the key.

       commentlen is the total size in bytes of the comment pointed to by the comment argument

       typemask is a  bitmask  that  specifies  format  and  info  about  the  data  passed  to  this  function.
       Specifically, it details what format the host name is, what format the key is and what key type it is.

       The   host   name   is   given   as   one   of   the   following   types:   LIBSSH2_KNOWNHOST_TYPE_PLAIN,
       LIBSSH2_KNOWNHOST_TYPE_SHA1 or LIBSSH2_KNOWNHOST_TYPE_CUSTOM.

       The  key  is  encoded  using  one   of   the   following   encodings:   LIBSSH2_KNOWNHOST_KEYENC_RAW   or
       LIBSSH2_KNOWNHOST_KEYENC_BASE64.

       The  key  is  using  one of these algorithms: LIBSSH2_KNOWNHOST_KEY_RSA1, LIBSSH2_KNOWNHOST_KEY_SSHRSA or
       LIBSSH2_KNOWNHOST_KEY_SSHDSS.

       store should point to a pointer that gets filled in to point to the known host data after  the  addition.
       NULL can be passed if you don't care about this pointer.

RETURN VALUE

       Returns a regular libssh2 error code, where negative values are error codes and 0 indicates success.
