Does this tool send my input data to any external servers?

No. All hashing and benchmarking operations are executed locally in your browser using WebAssembly via the hash-wasm library, ensuring your data remains private.

What do the 'Broken' and 'Modern' security statuses mean?

'Broken' indicates legacy algorithms like MD5 and SHA-1 where cryptographic collisions are computationally feasible. 'Modern' indicates secure algorithms like SHA-256, SHA-512, and the BLAKE family.

Can I input raw binary data instead of plain text?

Yes. You can input binary data by encoding it as hex or Base64 bytes and selecting the corresponding input encoding option.

How is the relative speed benchmark calculated?

The tool hashes the input data for the specified number of iterations, measures the execution time, and displays a relative throughput ratio compared to the fastest algorithm.

Why would I choose BLAKE3 over SHA-256?

BLAKE3 is highly optimized for modern hardware architectures and is typically much faster than SHA-256 while maintaining a highly secure cryptographic profile.

Examples

1. Comparing Modern Hash Performance

Backend Engineer

Background

A backend engineer is designing a high-throughput file storage service and needs to choose a fast, secure hashing algorithm to generate unique file identifiers.

Problem

They need to compare the speed and output format of SHA-256, SHA-512, and BLAKE3.

How to use

Enter a sample payload in the input text area, select SHA-256, SHA-512, and BLAKE3, set the output encoding to 'Both', and set iterations to 1000.

{
  "input": "hello world",
  "inputEnc": "utf8",
  "outputEnc": "both",
  "algos": ["sha256", "sha512", "blake3"],
  "iterations": 1000
}

Outcome

The comparison table displays the hex and Base64 digests alongside their bit lengths, showing BLAKE3 as the fastest algorithm in the relative throughput chart.

2. Verifying Legacy Checksums

Security Auditor

Background

An auditor is reviewing legacy system logs containing MD5 and SHA-1 hashes and wants to verify their values and highlight their security risks.

Problem

They need to generate MD5 and SHA-1 digests of a known string and document their 'Broken' security status.

How to use

{
  "input": "The quick brown fox jumps over the lazy dog",
  "inputEnc": "utf8",
  "outputEnc": "hex",
  "algos": ["md5", "sha1"],
  "iterations": 0
}
