{"library":"md5-o-matic","title":"MD5-o-matic","description":"md5-o-matic is a JavaScript utility for generating MD5 hashes in Node.js, distinguished by its claim of being fast and having zero module dependencies. The package's current stable version is 0.1.1, which was released over a decade ago, indicating it is no longer actively maintained. While historically valued for its performance and self-contained nature, MD5 as a cryptographic hash function is now considered insecure due to significant vulnerabilities, particularly its susceptibility to collision attacks. It should not be used for security-sensitive applications like password storage or digital signatures. Its utility today is limited to non-cryptographic checksums for verifying data integrity against unintentional corruption or for generating unique identifiers where collision resistance is not a security concern.","language":"javascript","status":"abandoned","last_verified":"Wed Apr 22","install":{"commands":["npm install md5-o-matic"],"cli":null},"imports":["import md5omatic from 'md5-o-matic';","const md5omatic = require('md5-o-matic');"],"auth":{"required":false,"env_vars":[]},"quickstart":{"code":"const md5omatic = require('md5-o-matic');\n\nconst testString = 'The quick brown fox jumps over the lazy dog';\nconst emptyString = '';\nconst dataBuffer = Buffer.from('Hello, World!', 'utf8');\n\n// Hash a standard string\nconst hash1 = md5omatic(testString);\nconsole.log(`MD5 for \"${testString}\": ${hash1}`);\n\n// Hash an empty string\nconst hash2 = md5omatic(emptyString);\nconsole.log(`MD5 for empty string: ${hash2}`);\n\n// Hashing binary data (e.g., a Buffer)\n// Note: md5-o-matic might stringify non-string inputs. \n// For robust binary hashing, Node.js's native 'crypto' module is recommended.\ntry {\n  const hash3 = md5omatic(dataBuffer.toString('binary')); // Attempt to make it work, but not ideal\n  console.log(`MD5 for Buffer \"Hello, World!\": ${hash3} (Note: conversion to string)`);\n} catch (e) {\n  console.error(\"md5-o-matic might not directly support Buffer input without conversion.\", e.message);\n}\n\n// Example of how it was benchmarked (from original jsperf idea)\nfunction runBenchmark() {\n  const startTime = process.hrtime.bigint();\n  for (let i = 0; i < 10000; i++) {\n    md5omatic('some string to hash many times for benchmark ' + i);\n  }\n  const endTime = process.hrtime.bigint();\n  const durationMs = Number(endTime - startTime) / 1_000_000;\n  console.log(`Hashed 10,000 strings in ${durationMs.toFixed(2)} ms`);\n}\n\nrunBenchmark();","lang":"javascript","description":"This quickstart demonstrates how to import `md5-o-matic` using CommonJS `require` and compute MD5 hashes for strings.
