A Python library that creates a canonicalized version of a JSON document for uniqueness checking, hashing, and cryptography
Note: Do NOT use this in a production environment yet, still working on performance and a formal standard for sorting lists
Basic usage
import jsoncanon
doc1 = {
"def": [5, 2, 1, 7],
"abc": 123
}
doc2 = {
"abc": 123,
"def": [5, 2, 1, 7]
}
jsoncanon.dumps(doc1)
jsoncanon.dumps(doc2)
jsoncanon.dumps(doc, sort_lists=True)yields :
{"abc":123,"def":[5,2,1,7]}
{"abc":123,"def":[5,2,1,7]}and :
{"abc":123,"def":[1,2,5,7]}respectively.
Excluded Keys
import jsoncanon
doc1 = {
"_id": "a4337bc45a8fc544c03f52dc550",
"name": "Robert Paulson",
"age": 55
}
jsoncanon.dumps(doc1, excluded_keys=['_id'])yeilds :
{"age":55,"name":"Robert Paulson"}| name | rank | runs | mean | sd | timesBaseline |
