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 char-
acters '[' 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_KNOWN-
HOST_TYPE_PLAIN, LIBSSH2_KNOWNHOST_TYPE_SHA1 or LIBSSH2_KNOWN-
HOST_TYPE_CUSTOM.
The key is encoded using one of the following encodings: LIBSSH2_KNOWN-
HOST_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.
