.SH NAME
|
|
libssh2_hostkey_hash - return a hash of the remote host's key
|
|
.SH SYNOPSIS
|
|
#include <libssh2.h>
|
|
|
|
const char *
|
|
libssh2_hostkey_hash(LIBSSH2_SESSION *session, int hash_type);
|
|
|
|
.SH DESCRIPTION
|
|
\fIsession\fP - Session instance as returned by
|
|
.BR libssh2_session_init_ex(3)
|
|
|
|
\fIhash_type\fP - One of: \fBLIBSSH2_HOSTKEY_HASH_MD5\fP,
|
|
\fBLIBSSH2_HOSTKEY_HASH_SHA1\fP or \fBLIBSSH2_HOSTKEY_HASH_SHA256\fP.
|
|
|
|
Returns the computed digest of the remote system's hostkey. The length of
|
|
the returned string is hash_type specific (e.g. 16 bytes for MD5,
|
|
20 bytes for SHA1, 32 bytes for SHA256).
|
|
.SH RETURN VALUE
|
|
Computed hostkey hash value, or NULL if the information is not available
|
|
(either the session has not yet been started up, or the requested hash
|
|
algorithm was not available). The hash consists of raw binary bytes, not hex
|
|
digits, so it is not directly printable.
