Cryptography

Hash Algorithm Comparator

Hash the same input with MD5, SHA-1, SHA-256, SHA-512, BLAKE2b, and BLAKE3 at the same time and compare them side by side: output length, hex/Base64 digest, security status (broken / modern), and a relative speed benchmark. Great for teaching, choosing a hashing algorithm, or sanity-checking checksums.

Quick start

Call this tool from your code in three languages.

cURL

curl -X POST 'https://api.elysiatools.com/en/api/tools/hash-algorithm-comparator' \
  -H 'Content-Type: application/json' \
  -d '{"input":"The quick brown fox jumps over the lazy dog","inputEnc":"utf8","outputEnc":"hex","algos":["md5","sha1","sha256","sha512","blake2b256","blake2b512","blake3"],"iterations":100}'

API reference

Send a POST request with your inputs as JSON. File parameters require a separate upload first.

Endpoint

HTTP

POST https://api.elysiatools.com/en/api/tools/hash-algorithm-comparator

Parameters

Name	Type	Required	Description
input	textarea	Yes	The bytes to hash. Interpreted according to the input encoding.
inputEnc	select	No	—
outputEnc	select	No	—
algos	select	No	Which algorithms to run. Leave default to compare all.
iterations	number	Yes	How many times to hash for the speed benchmark. Set to 0 to skip timing.

MCP integration

Add this tool to your Model Context Protocol server so AI agents can list and call it.
