Method: NETSNMP::SecurityParameters#encode

Defined in:
lib/netsnmp/security_parameters.rb

#encode(pdu, salt:, engine_time:, engine_boots:) ⇒ Array

Returns a pair, where the first argument in the asn structure with the encoded pdu, and the second is the calculated salt (if it has been encrypted).

Parameters:

  • pdu (#to_asn, #to_der) —

    the pdu to encode (must quack like a asn1 type)

  • salt (String) —

    the salt to use

  • engine_time (Integer) —

    the reported engine time

  • engine_boots (Integer) —

    the reported boots time

Returns:

  • (Array) —

    a pair, where the first argument in the asn structure with the encoded pdu, and the second is the calculated salt (if it has been encrypted)
