    pcdoyle released this 2026-04-30 13:49:43 +00:00 | 38 commits to main since this release

    Automatic Install

    Auto-detects your arch, downloads the right binary into $(pwd), and verifies its SHA-256 against the published SHA256SUMS:

    curl -fsSL https://copyfail.pcdoyle.dev/install.sh | sh

    Always grabs the latest release. Exits non-zero on checksum mismatch and removes the bad file.

    Binary Target When to grab
    cvecheck-linux-x86_64 Linux x86-64 (Intel/AMD 64-bit) Default for servers, desktops, laptops, most VMs/containers. Ubuntu/Debian/RHEL/Fedora/Rocky/Alma/Oracle/SUSE/Alpine/Arch on x86_64.

    Run uname and check the output.

    uname -m

# aarch64     -> cvecheck-linux-arm64
# i686 / i386 -> cvecheck-linux-x86

    Verify manually

    SHA256SUMS is published as a release asset alongside the binaries. Each
    line is <sha256> <filename>.
