I think the GUI widget trimmed so you in fact entered just first 64
bytes. Check with "display password" option...
And try commandline, at least I get
Error: Password is longer than 64 characters.

I really do not like encryption systems which quietly trims anything
pretending longer password is correct. This is recipe for disaster.

I changed return code for TCRYPT oversized passphrase to -EPERM
(So it is handled like "bad passphrase", just early, this is way
I prefer.)

Thanks,
Milan
