Hi,
we have created an application for our customer. Somehow this week it stopped working.
While debugging I found somehow "=" are dropped after unwrapping.
I can verify this with the Rest API.
First I wrap this:
{ "alg": "RSA-OAEP-256", "value": "08vUy8_Ub5mzmqbE7kZOXQ==" }
And the result after unwrapping is this:
{ "kid": "https://XXXXX.vault.azure.net/keys/wrapkey/xxxxx", "value": "08vUy8_Ub5mzmqbE7kZOXQ" }
This seemed to have changed recently. As we use rust in our application reverting the base64 now fails.
I also tried with another value, which only had one =, which resulted in the same behavior.
Did anyone experience the same?
