libsodium VS Tink

Libsodium has been around for a while, so probably the reason it was posted is that version 1.0.19 was just released: https://github.com/jedisct1/libsodium/releases/tag/1.0.19-RE...

Updated NuGet and Swift packages are going to be uploaded soon.

AEGIS-128X and 256X are not there yet, but if you need them, they are available in libaegis: https://github.com/jedisct1/libaegis

All the code from libaegis will eventually be merged into libsodium, including the incremental update API which is especially useful for TLS.

To version the dependency you can check the current stable tree in git and save the date and git hash.

To address both of these vulnerabilities, you should instead use a library that handles these sharp edges for you. A well received library in the security and cryptography communities is libsodium. It has high level functions that handle password hashing and data encryption for you, reducing the risk that you introduce vulnerabilities in your code, such as you have here.

In general, cryptography is really hard. So for example, an attacker could construct a message that if you signed would leak information, ie it reduces the space of possible keys such that it can be brute forced. I’m not entirely sure if you could do that with a transfer function. But it’s certainly possible. That said, there are a ton of smart devs trying to prevent that as well so I’m not assuming anything here. But prudent practices are likely good to follow. Be very careful calling anything from your cold wallet etc. Use disposable keys for anything a bit risky. I took a sec to google an example and this is the closest I could find. https://github.com/jedisct1/libsodium/issues/170

Hi everyone! I'm learning Rust while on a break between jobs, and as I'm particularly interested in interfacing Rust with C and in cryptography, I've decided to write a wrapper around libsodium (https://github.com/jedisct1/libsodium) in Rust. This is purely a hobby project and I probably won't ever release it as there are already some open-source Rust bindings available for the library.

Can anyone recommend between Librandombytes and libsodium ramdombytes?

> I wonder what people say when they find a bug despite you using standard crypto?

Not using TLS doesn't automatically mean you need to "roll your own crypto". They could have used a well documentend library such as Google Tink[1] instead of doing their own crypto.

I sort of rewrote google's tink project in rust. There is already a rust version by project oak but it didn't exactly jive.

PassManager uses the Tink library for encryption, which provides state-of-the-art** security for your passwords. Tink uses industry-standard encryption algorithms like AES to ensure that your passwords are kept safe from prying eyes.

Note that in the example jwt refers to the Tink jwt package.

What I can't tell is if the new version had any fixes related to the bug being discussed here

Even the slightest hiccup could leave me vulnerable. I don't want to roll my own encryption. I want to use something like tink (a secure crypto library by Google) but unfortunately they don't support node or Javascript (there's a library that was published 2 years ago).

I dont have an answer for you, but 2 resources that are worth checking out: https://developer.android.com/guide/topics/security/cryptography and https://developers.google.com/tink

> Do C (or something where the mapping to C is known), and lots of languages have FFI libs where wrapping that is fairly trivial

That is an interesting idea, yet still a lot of work, sadly. I was hoping somebody had done the legwork already. I looked at Tink [1] and age [2] based on my co-worker's recommendation, but they all seem to have limited implementations in other languages.
