Also: - add `LIBSSH2_DSA_ENABLE` to enable it explicitly. - test the above option in CI. - say 'deprecated' in docs and public header. - disable DSA in the CI server config. (OpenSSH 9.8 no longer builds with it by default) https://www.openssh.com/txt/release-9.8 Patch-by: Jose Quaresma - disable more DSA code when not enabled. Fixes #1433 Closes #1435

.SH NAME
|
|
libssh2_knownhost_add - add a known host
|
|
.SH SYNOPSIS
|
|
.nf
|
|
#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);

.SH DESCRIPTION
|
|
We discourage use of this function as of libssh2 1.2.5. Instead we strongly
|
|
urge users to use \fIlibssh2_knownhost_addc(3)\fP instead, which as a more
|
|
complete API. \fIlibssh2_knownhost_add(3)\fP is subject for removal in a
|
|
future release.
|
|
|
|
Adds a known host to the collection of known hosts identified by the 'hosts'
|
|
handle.
|
|
|
|
\fIhost\fP 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.
|
|
|
|
\fIsalt\P 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.
|
|
|
|
\fIkey\fP is a pointer to the key for the given host.
|
|
|
|
\fIkeylen\fP is the total size in bytes of the key pointed to by the \fIkey\fP
|
|
argument
|
|
|
|
\fItypemask\fP 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 (deprecated).
|
|
|
|
\fIstore\fP 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 do not care about
|
|
this pointer.
|
|
.SH RETURN VALUE
|
|
Returns a regular libssh2 error code, where negative values are error codes
|
|
and 0 indicates success.
|
|
.SH AVAILABILITY
|
|
Added in libssh2 1.2, deprecated since libssh2 1.2.5. Use
|
|
\fIlibssh2_knownhost_addc(3)\fP instead!
