NAME
encode_keychange - produce the KeyChange string for SNMPv3
SYNOPSIS
encode_keychange -t md5|sha1 [OPTIONS]
DESCRIPTION
encode_keychange produces a KeyChange string using the old
and new passphrases as described in Section 5 of RFC 2274
"User-based Security Model (USM) for version 3 of the Simple
Network Management Protocol (SNMPv3)". -t option is manda-
tory and specifies the hash transform type to use.
The transform is used to convert passphrase to master key
for a given user (Ku), convert master key to the localized
key (Kul), and to hash the old Kul with the random bits.
Passphrases are obtained by examining a number of sources
until success (in order listed):
command line options (see -N and -O options below);
the file $HOME/.snmp/passphrase.ek which should only
contain two lines with old and new passphrase;
standard input -or- user input from the terminal.
OPTIONS
-E [0x]<engineID> EngineID used for Kul generation.
<engineID> is intepreted as a hex string when preceeded
by 0x, otherwise it is treated as a text string. If no
<engineID> is specified, it is constructed from the
first IP address for the local host.
-f Force passphrases to be read from standard input.
-h Display the help message.
-N "<new_passphrase>"
Passphrase used to generate the new Ku.
-O "<old_passphrase>"
Passphrase used to generate the old Ku.
-P Turn off the prompt for passphrases when getting data
from standard input.
-v Be verbose.
-V Echo passphrases to terminal.
