System.SecurityException: Invalid Crypto Key

Hello,

We are using this SDK for all the API calls between Salesforce and Box and this was all good until last week. They started throwing the below error starting this week.

System.SecurityException: Invalid Crypto Key

Box Support team says this SDK is classified as Unofficial and they were not ready to support this issue. Did any of the users of this package face this issue? If so, have you overcome this issue?

Thanks in advance,
Harsha

Start by reproducing the failing Salesforce-to-Box API call that raises System.SecurityException: Invalid Crypto Key. Review the SDK's authentication and crypto-related behavior, then compare it with a successful call or relevant Box guidance. Done means identifying whether the SDK causes the failure and documenting a confirmed fix or workaround.
