This is used for signing, where a server encrypts data using their private key.

这用于签名，其中服务器使用其私钥加密数据。

So everything that you load has to be signed with a certain private key from Nintendo.

因此，您加载的所有内容都必须使用任天堂的某个私钥进行签名。

This acts like an unforgeable signature, as only the owner, using their private key, can encrypt.

就像一个不可伪造的签名，因为只有私钥的持有人能加密。

So everything is in order and you can't just load codes without having the private key.

所以一切都井井有条，你不能在没有私钥的情况下加载代码。

Now, they can send that box back to me and only I can open it, with my private key.

现在，他们可以将那个盒子发回给我，只有我可以用我的私钥打开它。

The problem is that this public key can actually be used to calculate your secret private key.

但问题在于，获得公钥之后是可以通过数学方法计算私钥的。

In the same way, a digital public key can encrypt something that can only be decrypted with a private key.

同样，数字公钥可以加密只能用私钥解密的东西。

The reverse is possible too: encrypting something with a private key that can be decrypted with a public key.

反过来也是可能的：用可以用公钥解密的私钥加密一些东西。

So, people can encrypt a message using a public key that only the recipient, with their private key, can decrypt.

因此，人们可以使用只有收件人使用他们的私钥才能解密的公钥来加密消息。

The FBI also managed to get hold of the private electronic key required to access the funds, allowing them, in effect, to steal the money back from the criminal gang.

SSH keys just use public key encryption to create a pair of SSH keys, a public key and a private key, and then you can give the server the public part of the key.

SSH 密钥只需使用公钥加密来创建一对 SSH 密钥，即公钥和私钥，然后您可以将密钥的公共部分提供给服务器。

So you copy the public key and then whenever you try to authenticate instead of using your password, it's gonna use the private key to prove to the server that you are actually who you say you are.

因此，您复制公钥，然后每当您尝试进行身份验证而不是使用密码时，它都会使用私钥向服务器证明您确实是您所说的人。
