I have a set of AEADs that, when I use yhsm-decrypt-aead with --key-handle 100900, gives a failure (AEAD integrity check failed) after processing around 100.000 files. When I pass it --key-handle 0x100900 it manages to process all files. I'm not sure this is enough information to track it down, but at least now the issue is recorded and people who run into the same issue can provide additional information.
