JSON Web Token (JWT)
RPC Fast operates with JSON Web Token. Here we explain the way it works
JSON Web Token (JWT) in simple words
It is a JSON object defined in the RFC 7519 open standard. It is a safe method of exchanging information and representing claims with a high level of security. If you enable it, only authorized requests will proceed.
JSON Web Token (JWT) is available on the Enterprise pricing plan only.
Apply JWT
Follow our step-by-step instructions to send JWT requests on RPC Fast.
Generate RSA-256 keys
RS256 is an asymmetrical key. After creating one, you receive both public and private keys. You will use the private one to create a signature and the public one to check its authenticity.
Enable JWT in RPC Fast
Login -> Dashboard -> App Page -> Settings
Tap ‘Add token’ in the JWT Token section and type the public RS256 key from the previous step.
Clicking on ‘Add’ to get a public ID
Generate the JSON Web Token
You should add JWT to all headers of requests to enable its work. To create a full-fledged JSON Web Token, you must fill out HEADER, PAYLOAD, and SIGNATURE cells.
Payload
Use an epoch converter to receive a UNIX timestamp from a human-readable one or apply a unified command.
Signature
Encode a header.
Encode a payload.
Encode an algorithm from the title.
Take it all together and sign via the specific command.
JSON Web Token
Now you have your JSON Web Token! It looks like an encoded header, signature, and payload.
You will need a debugger to verify it.
Sending requests with JSON Web Token
Add JWT to the request header entry to proceed with it correctly.
What should I do with a wrong JWT?
If you try sending requests with a wrong JWT or without it after enabling, a program will show the error 401 status code (security troubles). Disable JWT or enter the right one to continue operations.
Key rotation support
PRC Fast is OK with key rotation. All you need to do is to upload a new one.
