Create JSON Web Key (JWK)

To create JSON Web Signature (JWS) you need to create the signing certificate public and private key and then share public key with the AA.

You need to give the public key in the Certificate field when creating your FIU entity at the central registry aacommons portal. Refer - Create FIU Entity

Steps to create the signature keys.

1. Open https://mkjwk.org/ - This is an online JSON Web Key generator

2. Use RSA (encryption algorithm)

3. Key Size = 2048

4. Key Use = Signature

5. Algorithm = RS256

6. Key ID = Unique UUID (Use online UUID Generator to create an UUID)

7. Click generate to create the Public and Private Key

You will get 3 JSON objects.
