MD5 Hash Generator

// MD5 is not available in Web Crypto API (it only supports SHA-*)
// Use a library like 'js-md5' or the Node.js crypto module

// Node.js (built-in crypto)
const crypto = require('crypto')
const hash = crypto.createHash('md5').update('hello world').digest('hex')
console.log(hash) // → "5eb63bbbe01eeed093cb22bb8f5acdc3"

// With Unicode input
crypto.createHash('md5').update('cafe\u0301').digest('hex')
// → "4fad076bae205e95bec9dacea498e2ab"

import hashlib

# Basic MD5 hash
result = hashlib.md5(b'hello world').hexdigest()
print(result)  # → "5eb63bbbe01eeed093cb22bb8f5acdc3"

# Hash a string (must encode to bytes first)
text = 'hello world'
hashlib.md5(text.encode('utf-8')).hexdigest()
# → "5eb63bbbe01eeed093cb22bb8f5acdc3"

# Hash a file
with open('file.bin', 'rb') as f:
    md5 = hashlib.md5()
    for chunk in iter(lambda: f.read(8192), b''):
        md5.update(chunk)
    print(md5.hexdigest())

    data := []byte("hello world")

}

# Using md5sum (Linux) or md5 (macOS)
echo -n "hello world" | md5sum
# → 5eb63bbbe01eeed093cb22bb8f5acdc3  -

# macOS
echo -n "hello world" | md5
# → 5eb63bbbe01eeed093cb22bb8f5acdc3

# Hash a file
md5sum package.json
# → a1b2c3d4e5f6...  package.json

# Using openssl (cross-platform)
echo -n "hello world" | openssl md5
# → MD5(stdin)= 5eb63bbbe01eeed093cb22bb8f5acdc3
