Abstract

Methods and apparatus to provide extended object notation data are disclosed. An example apparatus includes a data handler having a first input to receive object data and a first output to output an object notation key-value pair for the object data; a string processor having a second input coupled to the first output and a second output to convey the object notation key-value pair without string literals; and a hashing and encryption handler having a third input coupled to the second output and a third output to convey the key-value pair signed with a private key, to convey the key-value pair encrypted with a public key, and to convey an indication that the encrypted key-value pair is encrypted in a key of the encrypted key-value pair.

First claim

What is claimed is:

1. JavaScript Object Notation generator circuitry comprising:
data handler circuitry having a first input to receive object data, a first output to output an object notation key-value pair for the object data, and a second input;
string processor circuitry having an input coupled to the first output and an output to convey the object notation key-value pair without string literals; and
hashing and encryption handler circuitry having an input coupled to the output of the string processor circuitry and an output coupled to the second input of the data handler circuitry, the hashing and encryption handler circuitry effecting at least one of:
signing the key-value pair with a private key,
encrypting the signed key-value pair with a public key, and
inserting in an object notation file an indication that the key-value pair is encrypted in a key of the key-value pair, and

the hashing and encryption handler circuitry determining a hash value of the encrypted key-value pair, inserting the hash value in the key in addition to the key, and inserting an indication that the key-value pair is hashed in the key in addition to the key.
