Fast(er) AES-based constructions for Rust and WebAssembly

  • AEGIS-128L
  • AEGIS-256
  • AES-128-CTR
  • AES-256-CTR
  • AES-128-OCB
  • AES-256-OCB
  • AES-128-GCM
  • AES-256-GCM
  • AES-128-CBC with PKCS#7 padding
  • AES-256-CBC with PKCS#7 padding
  • CMAC-AES-128

This is a set of AES-based constructions (AEAD, stream cipher, MAC) for WebAssembly applications written in Rust.

They are trivial to use and this crate has zero dependencies.

Benchmarks

Benchmarks can be run with the cargo wasix bench command.
