dsvpn VS block-ciphers

Personally I use dsvpn (https://github.com/jedisct1/dsvpn) which is super simple to setup and use, and it's made by the guy who created libsodium.

Hi, I am working on a project that's to be done in Ubuntu. The project is a vpn which will run in Ubuntu. I found a GitHub repository of a vpn named "Dead Simple VPN (DSVPN)". I am not a expert in Ubuntu and I really need someone's help in setting up the VPN. It says it just takes a couple of minutes to set up. Please help me out. I'll attach the GitHub link. https://github.com/jedisct1/dsvpn .

Or dsvpn which doesn't even require a kernel module.

> WireGuard is a good alternative but requires a surprisingly high amount of configuration

Not really. It has a bit of a learning curve, but once you get past it it's actually a joy to use.

But if you want something even simpler, there's https://github.com/jedisct1/dsvpn

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.

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.
