File Verification Guide

kodachi://docs/security/file-verify

Verify any Kodachi download, ISO, binary pack, or single service binary against the official checksums, entirely in your browser. Your file never leaves your device. This guide walks through the online verifier and the matching command-line steps.

Browser-side hashing BLAKE3 + SHA-256 Signature check Zero upload

01 On-device integrity-check Verify installed system files from the command line with the integrity-check service. 02 Security guide hub Return to the security category overview and its sibling guides. 03 Suite map See how verification fits into the wider Kodachi binary suite.

Verify Any File Before You Trust It

Instantly verify Kodachi ISOs, the binary pack, or any individual binary against official checksums published at kodachi.cloud. You can also use this tool to compute hashes for any file on your system, your file never leaves your browser.

100% Browser-Side, Zero Upload BLAKE3 / MD5 / SHA-1 / SHA-256 / SHA-384 / SHA-512

Privacy guarantee, Your file never leaves your device. All hash computations run locally in your browser using a Web Worker. Only the BLAKE3 and SHA-256 results are compared against publicly available Kodachi checksums fetched from kodachi.cloud.

How It Works

Select

For hash only, drop a single file. For hash + signature, select the ISO and its .sig together and drop both at once

Hash

Your browser computes BLAKE3, MD5, SHA-1, SHA-256, SHA-384, and SHA-512 via a Web Worker

Compare

SHA-256 checks release packages; BLAKE3 checks individual binaries, both run automatically

Audit

Check the file hash on VirusTotal, Hybrid Analysis, and other external scanners

Result

A verified match shows the exact product name and version; a mismatch shows a warning

Which hash is used for verification?

Kodachi uses two different algorithms depending on the file type:

File type	Algorithm	Examples
Release packages	SHA-256	Desktop ISO, Terminal ISO, binary pack (tar.gz)
Individual binaries	BLAKE3	tor-switch, health-control, dns-switch, and all other Kodachi services

Both comparisons happen automatically, just drop your file and the result will tell you exactly what matched and which algorithm confirmed it.

Verifying from the command line

You can also verify downloads using standard CLI tools:

# Compute BLAKE3 (install: cargo install b3sum)
b3sum kodachi-binary-name

# Compute SHA-256 (for ISOs and packages)
sha256sum kodachi-terminal-9.0.1.iso

# Compute all hashes
b3sum myfile && md5sum myfile && sha1sum myfile && sha256sum myfile && sha384sum myfile && sha512sum myfile
