6 snmpkey - Create SNMPv3 security keys for the Net::SNMP module
7
9 The "snmpkey" utility generates security keys based on a password and
10 an authoritativeEngineID passed on the command line. This key can then
11 be used by the Net::SNMP module instead of the plain text password when
12 creating SNMPv3 objects.
13
14 snmpkey <authProto> <password> <authEngineID> [<privProto> [<password>]]
15
17 The User-based Security Model used by SNMPv3 defines an algorithm which
18 "localizes" a plain text password to a specific authoritativeEngineID
19 using a one-way hash. This resulting key is used by the SNMP
20 application instead of the plain text password for security reasons.
21
22 The Net::SNMP module allows the user to either provide a plain text
23 password or a localized key to the object constructor when configuring
24 authentication or privacy. The "snmpkey" utility can be used to
25 generate the key to be used by the -authkey or -privkey named arguments
26 when they are passed to the Net::SNMP "session()" constructor.
27
29 The "snmpkey" utility requires at least three command line arguments.
30 The first argument defines which hash algorithm to use when creating
31 the authKey. Either HMAC-MD5-96 or HMAC-SHA-96 can be specified with
32 the string 'md5' or 'sha' respectively. This choice must match the
33 algorithm passed to the -authprotocol argument when creating the
34 Net::SNMP object. The second argument is the plain text password that
35 is to be localized to create the authKey. The third required argument
36 is the authoritativeEngineID of the remote SNMP engine associated with
37 the Net::SNMP argument -hostname. The authoritativeEngineID is to be
38 entered as a hexadecimal string 10 to 64 characters (5 to 32 octets)
39 long and can be prefixed with an optional "0x".
40
41 The last two arguments are optional and can be used to determine how
42 the privKey will be generated. By default, the fourth argument assumes
43 a value of 'des' corresponding to the default privacy protocol defined
44 in the User-based Security Model. The Net::SNMP module supports
45 CBC-3DES-EDE and CFB128-AES-128 as alternatives to the default protocol
46 CBC-DES. These protocols can be chosen by specifying the string '3des'
47 or 'aes' respectively. This choice must match the protocol passed to
48 the -privprotocol argument when creating the Net::SNMP object. The
49 last argument can be used to specify the plain text password that is to
50 be localized to create the privKey. If this argument is not specified,
51 the authKey password is used.
