Hi,
I'm struggling with CAS 4.1.2 and webflow execution key. I'm trying to access a custom flow using url http://localhost:8080/cas/login?execution=<executionKey>&_eventId=myCustomEvent
It seems like for some reason the execution key can not be decrypted. It then tries to redirect me to an error page but it seems to start looping as it still decrypt the execution.
I'm pretty much out of ideas where to look next. Any pointers?

It seems like for some reason the execution key can not be decrypted. It then tries to redirect me to an error page but it seems to start looping as it still decrypt the execution.
Quick sanity check looks ok. The base64 data following the underscore in the flow execution ID is the encoded ciphertext; taking the length of that data and multiplying by 3 and dividing by 4 gives a whole number, which is correct. Obviously such a simple check isn't very reassuring, but it is a sanity check that rules out obvious truncation of the execution ID.
I'm pretty much out of ideas where to look next. Any pointers?
I'd rule out URL encoding errors before looking into decoding and decryption minutia.

Hi,
Thanks for the tips!
It does indeed seem like a URL encoding or rather decoding issue. The base64 data seems to have been url-encoded fine, the + characters are encoded to %2B. However when the key reaches ClientFlowExecutionRepository, It has been decoded so that the + characters have been replaced by whitespace. It seems to be this way already after it's through

Sorry, reply slipped. So it seems to be decoded twice in some way? %2B -> + and then + -> whitespace. But this seems to happen quite early in the request processing, much before it's handled by spring or cas. What am I doing wrong or is it all just very broken? :)
Thank you!
Tom

OK nevermind, it was all about missing URL encoding, aka. user error, as suspected.
Thanks though,
Tom
