I wanna create a Restful API using JWT with signature. The API only allows post method and there is request body in Json format. How do I add request Json body in JWT Signature?
https://localhost/Booking/Submit
JWT
.header {.alg="RS256"}
.payload { sender="ABC", recipient="XYZ", timestamp="010102020101010"}
.Signature {...}
Request Json body
{ "BookingId"=1, "BookingDate"="0404202001010", "BookedByName"="Mr. John", "BookedByContact"="12345678", "FacilitiyId"="10021"}
The JWT token is conventionally base64 encoded. This value is then added to your URL request as a header value for the “Authorization” key.
Your JSON payload is posted in the same URL request, except it makes up the body this time.

I am new to flutter. how to pass a security key and id in headers and convert the string in the base64 encoded value and send the request to backend?
I have one rest api.
which accept application/json request for an http post method .
all post parameters are optional.
The question is what is considered valid request in that case.
No value
{}
The second option represent json with no value.
Which is best practice for api?
I'm using OWASP ZAP to test our API. We have a couple of POST endpoints which use an API Token and a shared secret for authentication and validating the request.
Some parameters of the request body are concatenated and hashed using the shared secret. This value is inserted into the request header.
How can I programatically generate this signature using OWASP ZAP?
Request Header
Content-Type: "application/json"
Accept: "application/json"
API-Key: {API_KEY}
Signature: {hash(field_one + field_two + field_three + SHARED_SECRET)}
Request Body
{
"field_one": "abc",
"field_two": "123",
"field_three": "xyz"
}
The SHARED_SECRET is the password that is stored locally by the client and used to hash the three fields from the request.
It is stored on the server along with the API-Key so that requests can be identified and validated.
Use an HTTP Sender Script. Create it in the ZAP UI so that you can test it as you're writing it. First make sure you are just detecting the requests you want to change, then extract the field values you need and finally generate the hash. Keep testing at each stage to make sure its doing what you need. And if you need specific help theres always the zaproxy-scripts group.
Some JWT modules (e.g. pyjwt) throw an exception when decoding a JWT where the payload string encodes a list as opposed to a map/dict. I came across an api that sends such a JWT as a response to request and I need to decode it. I can use a custom method to decode the JWT, but I'm wondering if the api is going against the JWT protocol by encoding a list as the payload instead of encoding a dict with a key whose value is the list.
i am creating a rest api in which there is a need for transferring the apikey and a signature in the http headers. Now i can supply the required parameters inside the http header and a controller reads it out nicely but i was wondering if there is a better way of doing this.
We transfer the values of the apikey and sha1 signature in the HTTP Authorization header and retrieve this by using.
request.getHeader("AUTHORIZATION").split(',').
inject([:]) { map, token ->
token.split('=').with {
map[it[0]] = it[1]
}
map
}
The result is a map which contains the key/value pairs
Is there a better way of doing this?
