Many thanks to Jan for the helpful suggestions with which I have improved the code.
Unfortunately, it didn't solve the problem. I have cut down the code so that the encryption uses only a plaintext password, no sha1 hashing, no salt and no initial value. Thanks to Jan's Base64 encoding suggestion, I can see clearly that I get different encrypted values when running in the IDE to running the stack as a standalone. Here's the cutdown script: local tData local tDisplay local tPassword on openStack put "12345678" into tPassword end openStack on encryptMSG put Field "In" into tData encrypt tData using "aes256" with password tPassword put it into tDisplay put the base64Encode of tDisplay into Field "Out" end encryptMSG on decryptMSG put the base64Decode of Field "In" into tData decrypt tData using "aes256" with password tPassword put it into Field "Out" end decryptMSG When I encrypt Is this a bug? in the IDE the encrypted value is U2FsdGVkX1+phY3qAHj6kKxYtytOeLA7K/TM+9tfP+Y= but in the standalone it is U2FsdGVkX1/wFDjazwOsvXrEzPHQNcmvBa6nfU2rSJE= I wonder if it is the standalone settings that I am using as in addition to this difference, as I also cannot copy the contents of Field "Out" to the clipboard using command-C in the standalone. (Though apart from selecting Intel only, I haven't changed any of the default settings).
