Ok, I will need to a bit of refactoring then. What would be the default - "give up" if a file fails and print to the Rails log? This would...

This is confirmed fixed with the 0-byte hack above. ```ruby jwk_payloads = [ "{\"keys\":[{\"kty\":\"EC\",\"crv\":\"P-256\",\"x\":\"0Nv5IKAlkvXuAKmOmFgmrwXKR7qGePOzu_7RXg5msw\",\"y\":\"FqnPSNutcjfvXNlufwb7nLJuUEnBkbMdZ3P79nY9c3k\"}]}", "{\"keys\":[{\"kty\":\"EC\",\"crv\":\"P-256\",\"x\":\"xGjPg-7meZamM_yfkGeBUB2eJ5c82Y8vQdXwi5cVGw\",\"y\":\"9FwKAuJacVyEy71yoVn1u1ETsQoiwF7QfkfXURGxg14\"}]}",...

@excpt I've put up a PR if you want to take a look

You could try reproducing by roundtripping the example keys I've added to the test. If they come out truncated - this might as well be a bug in OpenSSL. Now...
