crypto_secretbox_easy produces different results on 32 bit and 64 bit processes given same values

[randynmary]

crypto_secretbox_easy in my testing produces different encryption results for same message, subkey, context and nonce on 32 bit and 64 bit processes. I have been using libsodium 1.0.20 for encryption of data at rest and my tests are showing that crypto_secretbox_easy produces a different encrypted value depending on whether the x64 or x86 (32 bit) version of the libsodium.dll is picked up. Is this expected? It makes crypto_secretbox_easy unuseable as in future we may migrate the application from 32 to 64 bit or a 64 bit application decrypting the data will be unable to do so. Is there a way to resolve this by calling a lower-level method or other way to make the 32 and 64bit versions produce the same results? Thanks.

This isn't expected, and may be an issue with the bindings or your application.
