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.

| 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.
