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.
