overflowing_literals false positive
overflowing_literals false positive

In a future version of Rust the `overflowing_literals` lint will become deny by default. See rust-lang/rust#55632. When checking for breakage in crates uploaded to crates.io it was discovered that this crate will no longer compile thanks to this lint. The error produced is [here](https://crater-reports.s3.amazonaws.com/pr-55632/try%23dc13be39fae8d4c607889b27de374b52586485a3/gh/BProg.des_chipher_rust/log.txt). This PR should fix the false positive.
