| .SH NAME
 | |
| libssh2_knownhost_check - check a host+key against the list of known hosts
 | |
| .SH SYNOPSIS
 | |
| .nf
 | |
| #include <libssh2.h>
 | |
| 
 | |
| int
 | |
| libssh2_knownhost_check(LIBSSH2_KNOWNHOSTS *hosts,
 | |
|                         const char *host,
 | |
|                         const char *key, size_t keylen,
 | |
|                         int typemask,
 | |
|                         struct libssh2_knownhost **knownhost);
 | |
| .fi
 | |
| .SH DESCRIPTION
 | |
| Checks a host and its associated key against the collection of known hosts,
 | |
| and returns info back about the (partially) matched entry.
 | |
| 
 | |
| \fIhost\fP is a pointer the host name in plain text. The host name can be the
 | |
| IP numerical address of the host or the full name.
 | |
| 
 | |
| \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 or LIBSSH2_KNOWNHOST_TYPE_CUSTOM.
 | |
| 
 | |
| The key is encoded using one of the following encodings:
 | |
| LIBSSH2_KNOWNHOST_KEYENC_RAW or LIBSSH2_KNOWNHOST_KEYENC_BASE64.
 | |
| 
 | |
| \fIknownhost\fP if set to non-NULL, it must be a pointer to a 'struct
 | |
| libssh2_knownhost' pointer that gets filled in to point to info about a known
 | |
| host that matches or partially matches.
 | |
| .SH RETURN VALUE
 | |
| \fIlibssh2_knownhost_check(3)\fP returns info about how well the provided
 | |
| host + key pair matched one of the entries in the list of known hosts.
 | |
| 
 | |
| LIBSSH2_KNOWNHOST_CHECK_FAILURE - something prevented the check to be made
 | |
| 
 | |
| LIBSSH2_KNOWNHOST_CHECK_NOTFOUND - no host match was found
 | |
| 
 | |
| LIBSSH2_KNOWNHOST_CHECK_MATCH - hosts and keys match.
 | |
| 
 | |
| LIBSSH2_KNOWNHOST_CHECK_MISMATCH - host was found, but the keys did not match!
 | |
| .SH AVAILABILITY
 | |
| Added in libssh2 1.2
