安装
- 不值为何，node_modules/bcrypt/examples/forever_gen_salt.js 其他版本一直报错，只有3.0.0版本可用，如下
node forever_gen_salt.js
dyld: lazy symbol binding failed: Symbol not found: __ZN4node19GetCurrentEventLoopEPN2v87IsolateE

- bcrypt文档介绍，安装需要node的稳定版本；
- 用nvm切换到node的10.0版本，即可安装
bcrypt使用
// 获取密钥
bcrypt.genSalt(10, function(err, salt) {
console.log('salt: ' + salt);
console.log('salt cb end: ' + (Date.now() - start) + 'ms');
// 用密钥salt，加密字符串test
bcrypt.hash('test', salt, function(err, crypted) {
console.log('crypted: ' + crypted);
console.log('crypted cb end: ' + (Date.now() - start) + 'ms');
console.log('rounds used from hash:', bcrypt.getRounds(crypted));
// 比较，成功
bcrypt.compare('test', crypted, function(err, res) {
console.log('compared true: ' + res);
console.log('compared true cb end: ' + (Date.now() - start) + 'ms');
});
// 比较，失败
bcrypt.compare('bacon', crypted, function(err, res) {
console.log('compared false: ' + res);
console.log('compared false cb end: ' + (Date.now() - start) + 'ms');
});
});
})
