nodejs-md5
A simple node module to give you the MD5 of a file or string.
Mimics the macOS command md5
.
To install:
npm install nodejs-md5
To import:
var md5 = require("nodejs-md5");
Example Usage:
To get the MD5 of a file:
//md5 ./test/testfile.txtmd5.file("./test/testfile.txt", function(err, md5) { if (err) { console.log(err); } else { console.log(md5); //"MD5 (testfile.txt) = f0ffb8dbde05931dfb9baeee5c86b214" }});
//md5 -q ./test/testfile.txtmd5.file.quiet("./test/testfile.txt", function(err, md5) { if (err) { console.log(err); } else { console.log(md5); //'f0ffb8dbde05931dfb9baeee5c86b214' }});
//md5 -r ./test/testfile.txtmd5.file.quiet("./test/testfile.txt", function(err, md5) { if (err) { console.log(err); } else { console.log(md5); //'f0ffb8dbde05931dfb9baeee5c86b214 file.txt' }});
To get the MD5s of multiple files in one shot:
//md5 ./test/testfile.txt ./test/anotherTestFile.txtmd5.files(["./test/testfile.txt", "./test/anotherTestFile.txt"], function(err, md5s) { if (err) { console.log(err); } else { console.log(md5s); //[ 'MD5 (testfile.txt) = f0ffb8dbde05931dfb9baeee5c86b214', 'MD5 (anotherTestFile.txt) = 59a8935a0ac35991c27f29d4f25ea8b9' ] }});
//md5 -q ./test/testfile.txt ./test/anotherTestFile.txtmd5.files.quiet(["./test/testfile.txt", "./test/anotherTestFile.txt"], function(err, md5s) { if (err) { console.log(err); } else { console.log(md5s); //[ 'f0ffb8dbde05931dfb9baeee5c86b214', '59a8935a0ac35991c27f29d4f25ea8b9' ] }});
//md5 -r ./test/testfile.txt ./test/anotherTestFile.txtmd5.files.reverse(["./test/testfile.txt", "./test/anotherTestFile.txt"], function(err, md5s) { if (err) { console.log(err); } else { console.log(md5s); //[ 'f0ffb8dbde05931dfb9baeee5c86b214 file.txt', '59a8935a0ac35991c27f29d4f25ea8b9 file.txt' ] }});
To get the MD5 of a string:
//md5 -s "Hello, world"md5.string("Hello, world", function (err, md5) { if (err) { console.log(err); } else { console.log(md5); //'MD5 ("Hello, world") = bc6e6f16b8a077ef5fbc8d59d0b931b9' }});
//md5 -qs "Hello, world"md5.string.quiet("Hello, world", function (err, md5) { if (err) { console.log(err); } else { console.log(md5); //"bc6e6f16b8a077ef5fbc8d59d0b931b9" }});
//md5 -rs "Hello, world"md5.string.reverse("Hello, world", function (err, md5) { if (err) { console.log(err); } else { console.log(md5); //'bc6e6f16b8a077ef5fbc8d59d0b931b9 "Hello, world"' }});
