- .SH NAME
- libssh2_knownhost_add - add a known host
- .SH 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);
- .SH DESCRIPTION
- 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.
-
- 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".
-
- \fIsalt\fP 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
-
- \fIcomment\fP is a pointer to a comment for the key.
-
- \fIcommentlen\fP is the total size in bytes of the comment pointed to by the \fIcomment\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.
-
- \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 don't 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 1.2.5
