Raspberry Pi?
If your hardware is compromised, you've got a problem anyway. And it's more likely for commonly used computer systems to be compromised, like desktop PCs and laptops, than something as geeky as a Raspberry. Other than that, those things are far easier to carry wherever, and have no wifi built in as far as I know. Most/all of the storage is removable, and you could probably set said storage to be read-only.
If you're going to build an air-gapped encryption/decryption device, you might as well go for a Raspberry Pi.
