NAME

       libssh2_knownhost_writeline - convert a known host to a line for storage

SYNOPSIS

       #include <libssh2.h>

       libssh2_knownhost_writeline(LIBSSH2_KNOWNHOSTS *hosts,
				   struct libssh2_knownhost *known,
				   char *buffer, size_t buflen,
				   size_t *outlen,
				   int type);

DESCRIPTION

       Converts a single known host to a single line of output for storage, using the 'type' output format.

       known identifies which particular known host

       buffer points to an allocated buffer

       buflen is the size of the buffer. See RETURN VALUE about the size.

       outlen  must  be  a pointer to a size_t variable that will get the output length of the stored data chunk. The number does not included the
       trailing zero!

       type specifies what file type it is, and LIBSSH2_KNOWNHOST_FILE_OPENSSH is the only currently supported format.

RETURN VALUE

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

       If the provided buffer is deemed too small to fit the data libssh2 wants to store in it, LIBSSH2_ERROR_BUFFER_TOO_SMALL will  be  returned.
       The application is then advised to call the function again with a larger buffer. The outlen size will then hold the requested size.

AVAILABILITY

       Added in libssh2 1.2

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 numeri-
       cal 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. Specificly, 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_KNOWN-
       HOST_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!
