JWE configuration

For some endpoints we need from you enc and alg from JWE parameters. Acceptable values are:

  • Algorithm used by Verestro to encipher content of message (enc) - A256GCM,
  • Algorithm used by Verestro to encipher encryption key (alg) - RSA-OAEP-256,
  • Algorithm needed from you to encipher content of message (enc) - A256GCM,
  • Allowed algorithms for key encryption (alg) - RSA-OAEP-256  or  RSA-OAEP.

Request:

To process encrypted message you need to perform a few additional steps on top of standard message processing:

  • Verestro add headlines:
    • Public-Key through which you can encrypt response to us (if needed),
    • Encrypted-Request headline confirming message encryption; value true or false,
  • Expose endpoint with your Public Key - you will find a similar endpoint in our technical documentation, GET /secure/public_key
  • Use Verestro Public Key to create JWE and transfer data in payload,

Response:

When the response contains sensitive data that requires encryption, use Verestro public key encryption available here GET /secure/public_key

Additional information:

  • In case of errors (i.e. validation errors) you will receive unencrypted response,

    • ENCRYPTION_REQUIRED,

    • INVALID_PUBLIC_KEY,

    • INVALID_PAYLOAD,

    • CANT_DECRYPT_PAYLOAD.
