公钥电子邮件加密 [英] public key email encryption

问题描述

谁的电子邮件完全加密？

Who has their email fully encrypted ?

我想加密我的电子邮件，但我不知道如何开始。如果我使用加密的电子邮件，并发送电子邮件给没有加密他的电子邮件的人如何接收器读取电子邮件？

I would like to encrypt my email but I am not sure how to start. If I use encrypted email and I send an email to someone who does not encrypt his email how can the receiver read the email ?

您建议在哪个电子邮件客户端上运行一个windows系统加密电子邮件？我正在使用Thunderbird。

What email client would you recommend to run on a windows systems for encrypted email ? I am using Thunderbird at the moment.

据了解，您必须生成2个密钥（一个公共和一个私人密钥），但是如何生成此密钥？我也认为你必须把你的钥匙放在某个地方下载，但是我不明白你如何信任下载的钥匙。

As I understand you have to generate 2 keys (one public and one private) but how do you generate this key? I also think that you have to put your key somewhere to download but I don't understand how you can trust the downloaded keys.

任何链接到一个好的（不是太复杂的）关于电子邮件加密实施的指导将非常感谢。

Any links to a good (not too complicated) guide about the working an implementing of email encryption would be very much appreciated.

推荐答案

Thunderbird与Enigmail是一个很好的免费的解决方案，你想做什么。我使用Outlook和PGP，但我认为它们大致相同。

Thunderbird with Enigmail is a great free solution for what you’d like to do. I use Outlook and PGP, but I think they’re approximately the same.

有关公钥/私钥加密查看维基页面，但我会在这里总结一下。

For a detailed explanation of public/private key encryption check out the wiki page, but I’ll try to sum up here.

要加密消息，除了接收者（bob）之外，没有人可以查看它，您可以使用Bob的公钥加密消息。公钥允许您加密，但不能解密。没有公钥，你不能加密消息，所以不用担心加密一个没有人可以解密的消息。

To encrypt a message so that nobody else but the receiver (bob) can view it you encrypt the message using Bob’s public key. The public key allows you to encrypt but not to decrypt. Without a public key you cannot encrypt a message, so there is no worry about encrypting a message that nobody can decrypt.

当Bob收到你的消息时，他将使用他的私钥解密消息。他保密这个私钥非常秘密，所以没有人可以解密他的邮件。
要发送加密的消息，Bob将使用_your公钥（您之前发送过的密钥）来加密消息。那么他会发送给你，你可以使用你的私钥解密它。

When Bob receives your message he will use his private key to decrypt the message. He keeps this private key very secret so that nobody else can decrypt his mail. To send an encrypted message back Bob will use _your public key (which you have sent him before) to encrypt a message. Then he will send it to you and you can decrypt it using your private key.

说我用于我的邮件的解决方案是使用机会性加密，所以如果我有我的邮件收件人的公钥，它被自动加密，如果我没有，它没有。这并不能防止我意外地向一个没有公钥的人发出一个秘密信息。为此，我必须非常小心，始终验证我拥有秘密信息所需的所有密钥。

That said the solution that I use for my mail is to use opportunistic encryption, so if I have the public key of any recipient of my mail message it gets automatically encrypted, if I do not, it doesn’t. This doesn’t protect me from accidentally sending out a secret message to a person that I don’t have a public key for however. For that I have to be very careful to always verify I have all the keys I need to have for secret messages.

为了做到这一点，我有一个电子邮件规则设置说，如果我在主题行中有[PGP]一词，它将不允许邮件被不加密地发送。如果我尝试它会抛出错误，并提醒我我的错误。

In order to do this I have an e-mail rule setup that says that if I have the word [PGP] in the subject line it will not allow the message to be sent unencrypted. If I try to it will throw an error and warn me of my mistake.

enigmail 网站有一个很好的描述，如何设置雷鸟来加密你的消息。

The enigmail site has a good description on how to setup thunderbird to encrypt your messages.
