MD5 Generator

md5​

The md5 function computes an MD5 digest of the given string using a pure JavaScript implementation.

Function Signature​

md5(str: string): string

Parameters​

ParameterTypeDescription
strstringInput text to hash.

Return Value​

Returns the MD5 hash as a 32-character hexadecimal string.

Example Usage​

import { md5 } from 'nhb-toolbox/hash';

const hash = md5("hello");
// → "2a40415d762a4bbc919d71b992c51710"

const emptyHash = md5("");
// → "d98c1dd404b2008f980980e97e42f8ec"

const fileHash = md5("file content");
// → "3f4c0bd16db223f13ad468c0232def8b"

Characteristics​

  • Pure JavaScript implementation - runs on any JavaScript engine
  • Deterministic output - same input always produces same output
  • 32-character hex output - fixed length regardless of input size
  • One-way function - cannot be reversed to obtain original input
Compatibility Note

The output may differ from other MD5 implementations due to algorithmic or encoding variations, but is consistent within this implementation.

Common Uses​

  • Checksum verification
  • Data integrity checking
  • Non-cryptographic hashing
  • File fingerprinting

Security Note​

MD5 is considered cryptographically broken and unsuitable for security-sensitive applications. Use stronger hashes like SHA-256 for security purposes.

Internal Usage​

This function is used internally for UUID v3 generation:

// Used inside UUID v3
const digest = md5(namespace + name);
