Digest verification failed for Reference

Question

I have implementation of a custom STS. After being authenticated and redirected but before the page was loaded I would receive this error:

[CryptographicException: Digest verification failed for Reference '#_8e0aea1a-713d-4536-8fac-a768073395e9'.]

The reference number would change every time I tried.

Answer 1

I eventually found out that the claims, I had loaded from the database, had carriage return line feeds. Once I replaced those I had no more issues.
