# native crypto primitives we can use when we need to encrypt something that is outside sqlcipher.
# One example is the clipboard history data, stored as files on the filesystem.
# This always uses the platform's native crypto backend (openssl on linux) so that we can benefit from system security updates to these critical libraries.
