facebook新加密货币_如何使用“秘密对话”模式加密您的Facebook消息
facebook新加密货币
Facebook has finally gotten with the times and rolled out device-to-device encrypted communication to all of the billion Facebook Messenger users. Here’s how to turn it on, which shortcomings to be aware of, and why you should start using it now.
Facebook终于与时俱进，并向所有十亿Facebook Messenger用户推出了设备到设备的加密通信。 这是打开它的方法，需要注意的缺点，以及为什么现在应该开始使用它。
什么是秘密对话(不是) (What Secret Conversation Is (and Isn’t))
Let’s lead with the good stuff: Secret Conversation is a new feature in the Facebook Messenger mobile app that provides end-to-end encryption between devices running the most current version of the application (if you haven’t updated Facebook Messenger recently, now would be the time to do so before reading on).
让我们先介绍一些好东西：秘密对话是Facebook Messenger移动应用程序中的一项新功能，该功能可在运行最新版本应用程序的设备之间提供端到端加密(如果您最近未更新Facebook Messenger，现在可以在阅读之前请先这样做)。
Even better, it’s not just some “It’s secure because we say it’s secure!” setup. The underpinnings of Secret Conversation is the Open Whisper Systems peer-reviewed Signal protocol used by the popular iOS/Android private messaging app Signal. In fact, if you’re in the mood for it, you can even read Facebook’s publicly available whitepaper on their adoption of the protocol and its Messenger integration.
更好的是，这不仅仅是“安全，因为我们说它是安全的！” 建立。 秘密对话的基础是流行的iOS / Android私人消息传递应用Signal使用的Open Whisper Systems同行评审的Signal协议。 实际上，如果您愿意的话，甚至可以阅读Facebook公开发布的白皮书，了解他们采用该协议及其Messenger集成。
While that’s all super awesome, the whole thing isn’t without a few shortcomings. First of all, it requires the Facebook Messenger app–this feature isn’t available on the desktop version of Facebook.
虽然这一切都很棒，但整个过程并非没有一些缺点。 首先，它需要Facebook Messenger应用程序-桌面版Facebook上不提供此功能。
In addition, while the feature is turned on by default (depending on your device), your messages aren’t encrypted by default–you have to manually start a secret conversation in order to use encryption. In 2016, heavy duty encryption should be the norm. Further, if your chat partner is using an older copy of Messenger because they haven’t (or can’t) upgrade, then you can’t use the encryption with them. It also doesn’t work with group chats because it’s a device-to-device system, and presently doesn’t support multi-user encryption (and won’t support this feature in the foreseeable future).
此外，默认情况下(取决于您的设备)启用此功能时，默认情况下不会对邮件进行加密-您必须手动启动秘密对话才能使用加密。 在2016年，重型加密应成为常态。 此外，如果您的聊天伙伴由于尚未升级(或无法升级)而使用Messenger的较旧版本，则您无法对其使用加密。 它也不适用于群聊，因为它是一个设备到设备的系统，并且目前不支持多用户加密(并且在可预见的将来将不支持此功能)。
In addition it doesn’t work with video, voice calling, or GIF files (which is fair because it would introduce a huge amount of overhead to encrypt those large files) but you can send images through the encrypted chat. Finally, because the encryption keys are device specific, unlike with traditional Messenger messages you can’t switch between your phone and your tablet and keep the same conversation going. The device you start a Secret Conversation on is the device you have to end it on, and you can only use it on one device at a time.
此外，它不适用于视频，语音呼叫或GIF文件(这很公平，因为这会引入大量开销来加密这些大文件)，但是您可以通过加密的聊天发送图像。 最后，由于加***是特定于设备的，因此与传统的Messenger消息不同，您无法在手机和平板电脑之间切换并保持相同的对话。 在其上启动“秘密对话”的设备是您必须终止该设备的设备，并且一次只能在一个设备上使用它。
All that said, however, the introduction of secure and proper end-to-end encryption in Facebook Messenger is a fantastic improvement–and it’s an improvement everyone should be taking advantage of. Given the enormous number of leaks over the last few years that indicate practically everyone is eavesdropping on our digital communications, you have nothing to lose from enabling encryption wherever you can.
尽管如此，在Facebook Messenger中引入安全和适当的端到端加密是一个了不起的改进-这是每个人都应该利用的改进。 鉴于过去几年的大量泄漏表明几乎每个人都在窃听我们的数字通信，因此，只要有可能，启用加密就不会有什么损失。
如何使用秘密对话 (How to Use Secret Conversation)
Now that we’ve gone through a quick run through of what Secret Conversation can and cannot do, let’s jump right into using it including creating new messages, setting self-destruct timers, and even wiping all your secret conversations at once.
现在，我们已经快速了解了“秘密对话”可以做什么和不能做什么，让我们直接使用它，包括创建新消息，设置自毁计时器，甚至一次擦除所有秘密对话。
选择要使用的设备 (Select Which Device You’ll Use)
Like we mentioned above, you can only use this feature on one device at a time, and you have to use that device for all your encrypted communication. If you only use Facebook Messenger on your phone, then no worries–jump right to the next section.
就像我们上面提到的，您一次只能在一个设备上使用此功能，并且必须使用该设备进行所有加密通信。 如果您仅在手机上使用Facebook Messenger，则无需担心-跳至下一部分。
If, on the other hand, you’ve got it installed on multiple devices–like an iPhone, an iPad, and an iPod Touch you use as a kick-around device to read social media in the bathroom with–you have to pick which one will be the carrier of the encrypted torch.
另一方面，如果您已将其安装在多种设备(例如iPhone，iPad和iPod Touch)上，则用作在浴室中阅读社交媒体的启动设备，则必须选择一个人将成为加密炬的载体。
By default, the first device you upgrade to the latest version of Facebook Messenger will be the one that the feature is turned on for. If you need to toggle it on for a different device, however, you can do so easily. Open Facebook Messenger on your device and tap the little silhouette “Me” icon in the lower corner.
默认情况下，升级到最新版本的Facebook Messenger的第一台设备将是启用该功能的设备。 但是，如果您需要为其他设备打开它，则可以轻松进行。 在设备上打开Facebook Messenger，然后点击右下角的小剪影“我”图标。
Scroll down until you see the settings entry for “Secret Conversation”. Tap on it.
向下滚动，直到看到“机密对话”的设置条目。 点击它。
Ensure “Secret Conversations” is toggled on.
确保已打开“秘密对话”。
Don’t worry about following up with your other devices, as soon as you turn the feature on while using your primary device, it will automatically be disabled on all the other devices.
不必担心跟上其他设备，一旦在使用主设备时打开该功能，该功能将在所有其他设备上自动禁用。
开始全新的秘密对话 (Starting a Brand New Secret Conversation)
There are two ways to start a Secret Conversation: you can start one fresh, or you can switch an existing conversation over. To start a fresh one with a friend, you simply tap on the compose icon at the top of Messenger’s home screen, like so.
有两种方法可以启动“秘密对话”：您可以重新开始一个秘密对话，也可以切换现有对话。 要与朋友开始一个新的朋友，您只需点击Messenger主屏幕顶部的撰写图标即可，就像这样。
Select “Secret” in the upper right hand corner of the screen.
选择屏幕右上角的“秘密”。
Once you select “Secret” just pick the friend you want to send the secret message to on the next page and you’re in business. We’ll pick our How-To Geek pal, Matt:
选择“秘密”后，只需在下一页上选择要向其发送秘密消息的朋友即可。 我们将挑选我们的How-To Geek朋友Matt：
The giant “Secret Conversation” and black lock icon tell you all you need to know: the conversation is now encrypted. Simply use Messenger like you otherwise would.
巨大的“秘密对话”和黑色锁定图标告诉您所有您需要了解的内容：对话现已加密。 像使用其他方式一样简单地使用Messenger。
从现有的会话切换到秘密会话 (Switching Over to a Secret Conversation From an Existing One)
Let’s say you’re already chatting with someone, however, and you want to jump to an encrypted the conversation. That’s a more likely scenario as the people you chat with the most frequently are also the ones you are most likely to want to securely communicate with.
假设您已经与某人聊天，但是您想跳转到加密的对话。 这是一种更有可能的情况，因为您最常与之聊天的人也是您最想与之安全通信的人。
Starting a Secret Conversation with them is simple. Just open up the existing message chain you have with them and tap on their name in the top navigation bar.
与他们进行秘密对话很简单。 只需打开与他们在一起的现有消息链，然后在顶部导航栏中点击它们的名称即可。
In the resulting contact menu, select “Secret Conversation” located roughly halfway down the screen.
在出现的联系人菜单中，选择位于屏幕下方大约一半的“秘密对话”。
Your conversation will now be converted to a “Secret Conversation” and you can begin sending messages back and forth.
现在，您的对话将转换为“秘密对话”，您可以开始来回发送消息。
Unlike the regular conversations where your text bubbles are blue, in “Secret Conversation” mode they will be black.
与文本气泡为蓝色的常规对话不同，在“秘密对话”模式下，它们将为黑色。
One small but important thing worth noting before we proceed: when you use this this trick to start a Secret Conversation with an existing chat partner, it doesn’t retroactively protect your existing conversation. In fact, it actually splits your conversational stream with them into two: your regular non-encrypted Facebook Messenger chat continues and a new Secret Conversation chat starts.
在继续之前，需要注意一个小而重要的事情：当您使用此技巧与现有聊天伙伴开始秘密对话时，它不会追溯保护您现有的对话。 实际上，它实际上将与您的对话流分成两部分：您的常规非加密Facebook Messenger聊天继续进行，并且新的Secret Conversation聊天开始。
You can see in the screenshot above how after starting a Secret Conversation with Matt we then have two conversations listed with him in Messenger.
您可以在上面的屏幕截图中看到与Matt进行秘密对话后，如何在Messenger中列出与他的两个对话。
启用自毁消息 (Enabling Self-Destructing Messages)
While everything else is the same when chatting in a Secret Conversation–you send pictures the same way, you chat back and forth the same way–there’s a new chat feature built into the new mode: Snapchat-like self-destructing messages.
在“秘密对话”中聊天时，其他所有操作都是相同的-您以相同的方式发送图片，以相同的方式来回聊天-新模式中内置了一项新的聊天功能：类似Snapchat的自毁消息。
When sending a message, simply tap on the clock icon located on the right hand side of the chat box.
发送消息时，只需点击聊天框右侧的时钟图标。
Once you tap the clock, you’ll have the option to select how long the message should exist after it is first viewed before expiring. You can select anywhere from 5 seconds to 1 day.
轻按时钟后，您可以选择在第一次查看消息后到到期前应该存在的时间。 您可以选择5秒钟到1天之间的任意时间。
Note that the chat box changes in two ways: it now indicates in red what the expiry time is and the clock icon is filled in. Also note that the sent message has been seen and there is a countdown next to it.
请注意，聊天框有两种更改方式：现在，它以红色指示到期时间，并且时钟图标已填充。另外，请注意，已看到已发送的消息，并且旁边有一个倒计时。
The expiration time will remain for all future messages unless you tap on the clock icon and select “Off” to disable message expiry.
除非您点击时钟图标并选择“关”以禁用消息到期，否则所有未来消息的到期时间都将保留。
确认您的秘密对话实际上是秘密 (Confirming Your Secret Conversation Is Actually Secret)
This particular step is completely optional on your part, but it’s fun (for the curious) and comforting (for the paranoid). If you wish you can compare the device keys used by your device and your chat partner’s device.
这一步对您来说是完全可选的，但是很有趣(对于好奇)和安慰(对于偏执狂)。 如果愿意，您可以比较您的设备和聊天伙伴的设备使用的设备**。
At any time you can click on
您随时可以点击
Here you will find you and your partner’s device keys, displayed in a long hexadecimal string. Remember these are device keys and specific to your physical device (and not to your Facebook login alone). This means if you switch between using Messenger on your iPhone to your iPad (or buy a new iPhone) the key will change with the hardware.
在这里，您将找到您和您伴侣的设备**，这些**以十六进制长字符串显示。 请记住，这些是设备**，特定于您的物理设备(而不是仅针对您的Facebook登录名)。 这意味着，如果您在使用iPhone上的Messenger和iPad(或购买新iPhone)之间切换，则**将随硬件而改变。
What I see as “Your Key” is what Matt should see as “Jason’s” key, and vice versa. By comparing these keys in person or in another secure fashion you can be extra double sure you’re communicating securely with each other. Again, however, outside the realm of the very curious or the very paranoid, this is definitely not a required step to use Secret Conversation mode.
我认为“您的钥匙”就是马特应该视为“杰森的”钥匙，反之亦然。 通过亲自比较或以其他安全方式比较这些**，可以进一步确保彼此之间的通信安全。 再次，但是，在非常好奇或非常偏执的领域之外，使用“秘密对话”模式绝对不是必需的步骤。
删除秘密对话 (Deleting Secret Conversations)
Finally, you may find that you wish to torch some or all of your Secret Conversations. You can approach this issue one of two ways. You can delete individual Secret Conversations at the chat level by tapping on your Secret Conversation chat partner’s name (as we just did to check the Device Keys) and then selecting “Delete Conversation”.
最后，您可能会发现自己希望割炬部分或全部“秘密对话”。 您可以采用以下两种方法之一来解决此问题。 您可以通过点击您的“秘密对话”聊天伙伴的姓名(就像我们刚检查设备**一样)，然后选择“删除对话”，来在聊天级别删除单个“秘密对话”。
You can also remove all Secret Conversations in one swoop by returning to the menu we first visited in the tutorial to check the status of Secrete Conversations on your device–Me > Secret Conversations–and select “Delete Secret Conversations”.
您还可以一口气删除所有“秘密对话”，方法是返回到我们在教程中首次访问的菜单，以检查设备上“秘密对话”的状态-“我>秘密对话”，然后选择“删除秘密对话”。
After confirming this will nuke all the Secret Conversations on your device.
确认后，将取消您设备上的所有秘密对话。
That’s all there is to it, with a little insight into how it all works (and sometimes doesn’t work) you can easily begin enjoying encrypted chat with all your Facebook Messenger pals.
这就是全部内容，只要稍微了解一下它们如何工作(有时不起作用)，您就可以轻松地与所有Facebook Messenger好友开始享受加密的聊天。
