NAME

       libssh2_knownhost_add - add a known host

SYNOPSIS

       #include <libssh2.h>

       int libssh2_knownhost_add(LIBSSH2_KNOWNHOSTS *hosts,
                                 char *host, char *salt,
                                 char *key, size_t keylen,
                                 int typemask,
                                 struct libssh2_knownhost **store);

DESCRIPTION

       We  discourage use of this function as of libssh2 1.2.5. Instead we strongly urge users to
       use   libssh2_knownhost_addc(3)   instead,    which    as    a    more    complete    API.
       libssh2_knownhost_add(3) is subject for removal in a future release.

       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.

       saltP  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

       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.

AVAILABILITY

       Added in libssh2  1.2,  deprecated  since  libssh2  1.2.5.  Use  libssh2_knownhost_addc(3)
       instead!
