在javascript中根据密码生成RSA密钥对 [英] Generate RSA key pair in javascript, based on a password

问题描述

根据我的理解，RSA密钥通常是基于（强）随机生成器生成的。

As far as I understand, RSA keys are usually generated based on a (strong) random generator.

而是，我想基于密码创建它们。

Instead, I want to create them based on a password.

或更确切地说是在其哈希上，例如sha512（sha512（password + salt）+ password + pepper）

Or rather on its hash, for example sha512(sha512(password+salt)+password+pepper)

这需要在客户端完成，在JavaScript中。

This needs to be done client side, in JavaScript.

有人会知道如何做到这一点吗？是否有一个容易的JavaScript库，基于给定的输入确定性地创建RSA密钥对？

Would anyone know how to do this? Is there an easy JavaScript library that creates RSA key pairs deterministically, based on a given input?

（实际上，我提到RSA，但任何安全的非对称加密都可以，我只需要公共 - 私人加密）

(Actually, I'm mentioning RSA but any secure asymmetrical encryption would suffice, I just need public-private encryption)

添加：我需要这个，因为我正在建立一些安全的通信解决方案，不需要依赖于连接甚至服务器是安全的。

Addition: I need this because I'm building some secure communication solution, that doesn't need to rely on the connection or even the server to be secure.

我使用随机密钥用AES加密所有内容，密钥是RSA加密的。这个想法是Alice可以使用Bob的公钥（因此Bob的公钥必须在线存储）对其内容（或者实际上是她的内容的AES密钥）进行RSA加密。

I'm encrypting all content with AES using random keys, and the keys are RSA-encrypted. The idea is Alice can RSA-encrypt her content (or actually, the AES-key for her content) with Bob's public key (therefore Bob's public key must be stored online).

稍后，当Bob再次输入他的密码时，他的浏览器可以确定地计算他的RSA私人&

Later, when Bob enters his password again, his browser can deterministically calculate his RSA private & public key on the spot, download the content from Alice, and decrypt it locally using his private key.
