  "arcup": {
    "<platform>": {
      "<version>": "<sha256_hash>"

}

Platforms: x86_64_linux, aarch64_linux, x86_64_macos, aarch64_macos

Verification

# Fetch checksum for a specific binary
curl -sSfL https://raw.githubusercontent.com/arcium-hq/arcium-checksums/main/checksums.json | \
  jq '.arcup.x86_64_macos["0.6.0"]'

# Verify a downloaded binary
sha256sum arcup | cut -d' ' -f1

Security Model

This repository is a separate trust domain from bin.arcium.com where binaries are hosted. An attacker must compromise BOTH to serve malicious binaries.

Automation

Checksums are automatically published by the arcium-tooling CI/CD pipeline when new releases are built.
