Why verify
Every download is a copy of a file on a server. Three things can go wrong:
- Network corruption.
A flaky connection can introduce bit errors. Modern HTTPS and TCP checksums catch most of these, but a router dropping a packet mid-stream can still corrupt a download.
- Disk full or out-of-space.
The browser silently truncates a partial download. The file looks like it downloaded fine, but it isn’t the whole thing.
- Server compromise.
The very rare but very serious case. An attacker who can write to the Beemuu.com server or the GitHub release could replace the installer with a tampered version.
SHA-256 verification catches all three. If the hash you compute matches the published hash, the file is the genuine Beemuu installer. If not, re-download.
Windows
Use certutil in Command Prompt or PowerShell:
certutil -hashfile BeeEmUu_0.14.4_x64-setup.exe SHA256 certutil -hashfile BeeEmUu_0.14.4_x64_en-US.msi SHA256
The output looks like:
SHA256 hash of BeeEmUu_0.14.4_x64-setup.exe: aa1b2c3d4e5f... (64 hex characters) CertUtil: -hashfile command completed successfully.
Compare the 64-character hash against the published hash below. A match confirms the file is genuine.
Alternative: PowerShell Get-FileHash
Get-FileHash -Algorithm SHA256 -Path .\BeeEmUu_0.14.4_x64-setup.exe
macOS
Use shasum in Terminal:
shasum -a 256 BeeEmUu_0.14.4_x64-setup.exe shasum -a 256 BeeEmUu_0.14.4_x64_en-US.msi
Or use the GUI: Finder → Get Info → More Info → SHA-256.
Linux
Use sha256sum in a terminal:
sha256sum BeeEmUu_0.14.4_x64-setup.exe sha256sum BeeEmUu_0.14.4_x64_en-US.msi
Published hashes for v0.14.4
| File | SHA-256 |
|---|---|
BeeEmUu_0.14.4_x64-setup.exe | 3a3b1e5a4e8c9d7f2b6c8a1d4e7f0c2b5a8d1e3f6c9b2a5d8e1f4c7b0a3d6e9f |
BeeEmUu_0.14.4_x64_en-US.msi | 4b4c2f6b5f9d0e8c3d7e9b2c5d8e1f0a3b6c8d0e3f6a9b1c4d7e0f3a5b8c1d4e7f0a3b6c8d |
The above hashes are placeholder values for documentation. The live, computed hashes for v0.14.4 are on the download page and on the GitHub release page.
Verification questions
What if the hash doesn’t match?
Re-download the file. The most common cause of a hash mismatch is a partial download — the browser thinks the file finished but a packet was dropped. If a re-download still doesn’t match, check the file size against the published size and report the discrepancy on GitHub.
Can I trust the published hash on this page?
Compare against the GitHub release page and the SHA-256 published in the release’s release notes. If the three sources agree, you can trust the file.
Why SHA-256 and not SHA-3 or BLAKE3?
SHA-256 is supported natively on every modern OS (Windows since 7, macOS, Linux) and on every relevant language. There is no security advantage to SHA-3 for this use case — SHA-256 is collision-resistant enough for installer verification.
