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

Select a File

Drop a file here or click to browse

Hash only — drop the ISO or binary alone  |  Hash + Signature — select the ISO and .sig together and drop them at once (the Kodachi public key is built in, no .pem needed)

0%

Signature verification — Attach the .sig file to verify authenticity (the Kodachi public key is already built in). For non-Kodachi files, also attach the signer's .pem public key. You can also drop the file and .sig together in one go.

Attach .sig Custom key (.pem)

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

1

Select

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

2

Hash

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

3

Compare

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

4

Audit

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

5

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
