Collection of message-authentication code algorithms (HMAC, CMAC, CBC‑MAC, PMAC, BelT, Retail) with faithful line-by-line transliteration and provenance headers for AST-distance tracking.
This is a Kotlin Multiplatform line-by-line transliteration port of RustCrypto/MACs.
Original Project: This port is based on RustCrypto/MACs. All design credit and project intent belong to the upstream authors; this repository is a faithful port to Kotlin Multiplatform with no behavioural changes intended.
This is an in-progress port. The goal is feature parity with the upstream Rust crate while providing a native Kotlin Multiplatform API. Every Kotlin file carries a // port-lint: source <path> header naming its upstream Rust counterpart so the AST-distance tool can track provenance.
The text below is reproduced and lightly edited from
https://github.com/RustCrypto/MACs. It is the upstream project's own description and remains under the upstream authors' authorship; links have been rewritten to absolute upstream URLs so they continue to resolve from this repository.
