martindisch / aes-ccm Goto Github PK

I just recently published the ccm crate. In addition to the tag size, it also supports variable nonce sizes. It successfully passes RFC 3610, NIST SP 800-38C and CAVP tests, the only untested branch is one responsible for authenticated data larger than 4 GiB.

When I include aes-ccm = "0.5.0" to my dependencies and try to build my project I am getting:

error: failed to select a version for the requirement `aes-soft = "^0.4"`
candidate versions found which didn't match: 0.99.99, 0.6.4, 0.6.3, ...
location searched: crates.io index
required by package `aes v0.4.0`
    ... which satisfies dependency `aes = "^0.4.0"` of package `aes-ccm v0.5.0`
    ... which satisfies dependency `aes-ccm = "^0.5.0"` of package `gsce v0.1.0 (/home/stefan/workspaces/eriptic/gsce)`

How to fix that?

Hello! Glad to see there's a Rust implementation of aes-ccm, which I may consider using soon for a particular project.

The aead crate provides traits which abstract over various AEAD modes:

https://github.com/RustCrypto/traits/tree/master/aead

Namely the Aead (and AeadMut) traits:

https://docs.rs/aead/latest/aead/trait.Aead.html

As of the 0.2 release, they now support an optional alloc feature (in addition to always being #![no_std]) along with a heapless feature to support usage in heapless (e.g. microcontroller) environments.

Is this something you'd be interested in using? If so, I can send a PR.

Do you plan on supporting Aes256?
