This constant is defined in crypto_box.h of libsodium C library. If you want to change it, you have to change it in the libsodium C library. I am not a cryptographer, so I prefer to use default constants and settings of libsodium C library set by the people who understand it more than I do. libsodium-jna is a thin wrapper around libsodium C library. Thanks.
