The data is encrypted using libsodium with the crypto_secretbox interface,. In most cases, it appears that supporting constant-time operation in the math/big package should require no modifications to the optimized arithmetic code in architecture-specific assembly, because that code tends to be already designed to use architecture-specific mechanisms for handling carries and such without requiring conditionals.
