nodejs-md5 ![Version][version]  ![Coverage Status][coveralls] ![Total Downloads][total]

A simple node module to give you the MD5 of a file or string.
Mimics the macOS command md5.

To install:

``bash
npm install nodejs-md5
`

To import:

`JavaScript
var md5 = require("nodejs-md5");
`

Example Usage:

#### To get the MD5 of a file:

`JavaScript
//md5 ./test/testfile.txt
md5.file("./test/testfile.txt", function(err, md5) {
if (err) {
console.log(err);
}
else {
console.log(md5); //"MD5 (testfile.txt) = f0ffb8dbde05931dfb9baeee5c86b214"
}
});
`

`JavaScript
//md5 -q ./test/testfile.txt
md5.file.quiet("./test/testfile.txt", function(err, md5) {
if (err) {
console.log(err);
}
else {
console.log(md5); //'f0ffb8dbde05931dfb9baeee5c86b214'
}
});
`

`JavaScript
//md5 -r ./test/testfile.txt
md5.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:

`JavaScript
//md5 ./test/testfile.txt ./test/anotherTestFile.txt
md5.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' ]
}
});
`

`JavaScript
//md5 -q ./test/testfile.txt ./test/anotherTestFile.txt
md5.files.quiet(["./test/testfile.txt", "./test/anotherTestFile.txt"], function(err, md5s) {
if (err) {
console.log(err);
}
else {
console.log(md5s); //[ 'f0ffb8dbde05931dfb9baeee5c86b214', '59a8935a0ac35991c27f29d4f25ea8b9' ]
}
});
`

`JavaScript
//md5 -r ./test/testfile.txt ./test/anotherTestFile.txt
md5.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:

`JavaScript
//md5 -s "Hello, world"
md5.string("Hello, world", function (err, md5) {
if (err) {
console.log(err);
}
else {
console.log(md5); //'MD5 ("Hello, world") = bc6e6f16b8a077ef5fbc8d59d0b931b9'
}
});
`

`JavaScript
//md5 -qs "Hello, world"
md5.string.quiet("Hello, world", function (err, md5) {
if (err) {
console.log(err);
}
else {
console.log(md5); //"bc6e6f16b8a077ef5fbc8d59d0b931b9"
}
});
`

`JavaScript
//md5 -rs "Hello, world"
md5.string.reverse("Hello, world", function (err, md5) {
if (err) {
console.log(err);
}
else {
console.log(md5); //'bc6e6f16b8a077ef5fbc8d59d0b931b9 "Hello, world"'
}
});
