Need help testing this on older platforms, like PPC. |

Add sha3-256 alongside the existing rmd160 and sha256 checksum types. SHA3-256 (Keccak, FIPS 202) is structurally independent from the SHA-2 family, providing genuine defense-in-depth rather than two variants of the same algorithm design. The Keccak-f[1600] permutation is taken from the XKCP reference implementation by the SHA3 designers (CC0 public domain), wrapped in a streaming Init/Update/Final API for compatibility with md_wrappers.h. The bundled implementation is used unconditionally since CommonCrypto lacks SHA3 before macOS 10.15 and the OpenSSL low-level SHA3 API is inconsistent across versions. For now, rmd160 remains in default_checksum_types and secure_checksum_types to allow the release containing this change to propagate before nudging maintainers to transition. The portfile(7) man page documents the recommended set as sha256, sha3-256 and size. See: https://trac.macports.org/ticket/63885 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
