hashes VS block-ciphers

If found this set of crates for other algorithms : https://github.com/RustCrypto/hashes And also found this set of crates that seem to include a lot of block cyphers : https://github.com/RustCrypto/block-ciphers Even if "des" is listed as a crate in this last link, it doesn't seem to provide the DES algorithm entirely.

Then you should note that here where they're in the process of rewriting the crate (and have already removed the unsafe block you pointed out): https://github.com/RustCrypto/hashes/pull/228

If you are trying to use it as a library in your own crate then I would suggest looking at the [patch.crates-io] section of your Cargo.toml. It should allow you to override the dependency and point it to something else. Under that section set aes = { git = 'https://github.com/RustCrypto/block-ciphers', rev = 'e59142b26edcaa5e287c7e5067be8a501b42f9cb' }, changing the rev key to whichever commit has the right version of the crate when it was published. Then do the same for block-cipher and any others that it cannot find the version for but with the correct repository and commit.

aes (GitHub: RustCrypto / block-ciphers / aes) good: still maintained as of now - last commit on GitHub is from October 2021 good: examples look easy to use good: has received an audit by NCC Group bad: seems a bit too low level - the example provided only shows usage with data that is exactly block sized - seems there is no padding handling for real world use cases

I have no idea which libraries have the best code for Raspberry Pi 4. I think it doesn't have hardware AES, so an implementation of AES that doesn't leak secret bits through side channels and is fast would be complicated. The code I would trust is this: https://github.com/RustCrypto/block-ciphers but I have no idea whether it has python bindings. I would also sorry about correctly reusing buffers or else the memory allocation would be the bottleneck.

You should look at this this: https://github.com/rust-cc/awesome-cryptography-rust and you probably need this: https://github.com/RustCrypto/block-ciphers

For example, here is a bitsliced AES S-box written in single assignment form. Granted that's not the entire cipher, but the entire cipher can be implemented that way if you so desire.
