string sha1 ( string $str [, bool $raw_output = false ] )

如果可选的 raw_output 设置为 TRUE，则 sha1 摘要以长度为 20 的原始二进制格式返回，否则返回值为 40 个字符的十六进制数。

crypto = require("crypto");
console.log( new Buffer(crypto.createHash('sha1').update("some text").digest()).toString('base64') );
// N8KqY8OHc8KYw5lURzJiw6HCoAV8HmMuw5p3
console.log( new Buffer(crypto.createHash('sha1').update("some text").digest("hex")).toString('base64') );
// MzdhYTYzYzc3Mzk4ZDk1NDQ3MzI2MmUxYTAwNTdjMWU2MzJlZGE3Nw==
console.log( new Buffer(crypto.createHash('sha1').update("some text").digest("base64")).toString('base64') );
// TjZwangzT1kyVlJITW1MaG9BVjhIbU11Mm5jPQ==

<?php
echo base64_encode(sha1("some text"));
// MzdhYTYzYzc3Mzk4ZDk1NDQ3MzI2MmUxYTAwNTdjMWU2MzJlZGE3Nw==
echo base64_encode(sha1("some text", true)); // <-- how to reproduce it on the nodejs?
