Cryptography Utilities

Md5 Checksum

Generates MD5 checksums for data integrity verification and file comparison. Access via MCP in Cursor or Windsurf, or REST API at `/v1/crypto/checksum/md5`. Pass any string to get its 32-character hexadecimal MD5 hash. While cryptographically weak for security, MD5 remains useful for non-cryptographic checksums and legacy system compatibility.

API Endpoint

GET /v1/crypto/checksum/md5

Code Examples

curl "https://tinyfn.io/v1/crypto/checksum/md5" \
  -H "X-API-Key: YOUR_API_KEY"

const response = await fetch('https://tinyfn.io/v1/crypto/checksum/md5', {
  headers: { 'X-API-Key': 'YOUR_API_KEY' }
});
const data = await response.json();
console.log(data);

import requests

response = requests.get('https://tinyfn.io/v1/crypto/checksum/md5',
    headers={'X-API-Key': 'YOUR_API_KEY'})
data = response.json()
print(data)

FAQ

How do I generate an MD5 checksum using MCP in Cursor?

Use the md5_checksum tool with your input string. The MCP tool returns the same 32-character hex digest as the REST endpoint.

What's the MD5 hash output format?

Returns a 32-character lowercase hexadecimal string, like 'd41d8cd98f00b204e9800998ecf8427e' for an empty string.

Is MD5 secure for password hashing?

No. MD5 is cryptographically broken and vulnerable to collision attacks. Use bcrypt, Argon2, or other secure hashing for passwords.

When should I use MD5 checksums?

For file integrity checks, cache keys, or legacy system compatibility where speed matters more than cryptographic security.

Can I verify file downloads with MD5?

Yes, but only against accidental corruption. MD5 can't detect malicious tampering — use SHA-256 or SHA-3 for security-critical verification.
