看看crypto。createhash (algorithm)

var filename = process.argv[2];
var crypto = require('crypto');
var fs = require('fs');

var md5sum = crypto.createHash('md5');

var s = fs.ReadStream(filename);
s.on('data', function(d) {
  md5sum.update(d);
});

s.on('end', function() {
  var d = md5sum.digest('hex');
  console.log(d + '  ' + filename);
});

crypto模块使这非常容易。

设置:

// import crypto from 'crypto';
const crypto = require('crypto');

const sha256 = x => crypto.createHash('sha256').update(x, 'utf8').digest('hex');

用法:

sha256('Hello, world. ');

在这里，您可以在您的硬件上对所有受支持的哈希值进行基准测试，这些哈希值由您的node.js版本所支持。有些是加密的，有些只是用于校验和。每个算法计算“Hello World”100万次。每个算法可能需要大约1-15秒(在标准谷歌计算引擎上使用Node.js 4.2.2测试)。

for(var i1=0;i1<crypto.getHashes().length;i1++){
  var Algh=crypto.getHashes()[i1];
  console.time(Algh);
  for(var i2=0;i2<1000000;i2++){
    crypto.createHash(Algh).update("Hello World").digest("hex");
  }
  console.timeEnd(Algh);  
}

我不得不把我的2美分扔在希望这能帮助某人。

对于那些使用CommonJS的人

const crypto = require('crypto');
const secret = 'I love writing code, fixing things and building helpful tools';
const hash = crypto.createHmac('sha256', secret).digest('hex');

console.log('Hash successfully generated: ', hash);

适用于使用ES模块的用户

const { createHmac } = await import('crypto');
const secret = 'I love writing code, fixing things and building helpful tools';
const hash = createHmac('sha256', secret).digest('hex');

console.log('Hash successfully generated: ', hash);

超级简单! 快乐编码:)

简单的一句话:

如果你想要UTF8文本哈希:

const hash = require('crypto').createHash('sha256').update('Hash me', 'utf8').digest('hex');

如果你想用Python, PHP, Perl, Github得到相同的散列:

const hash = require('crypto').createHash('sha256').update('Hash me', 'binary').digest('hex');

你也可以用sha1, md5, sha256, sha512替换sha256
