由于电子邮件服务顽固地坚持其Web 1.0 25MB 附件大小的限制，用户同时需要传输越来越大的文件的方法。
当然，如果安全不是问题，总是有云存储或暂时将文件留在您的网络域(web domain)上。但是，如果您需要一种通过Internet(Interwebs)传输文件的安全方式，则需要更安全(bit safer)的方式。
以下是五个安全文件传输(secure file transfer)选项，它们也是免费的。
我们转移(WeTransfer)
像往常一样，我们从两年前推荐给我的我最喜欢的开始。我喜欢WeTransfer，不仅因为它非常简单，而且因为它的上传和下载速度很快。我喜欢“正常工作”的东西，而且 WeTransfer 总是很活泼和踢屁股。
有免费选项和付费选项。免费选项允许最多 2GB 的文件传输，而无需注册帐户。
只需(Just)上传文件，然后添加您自己的电子邮件和个性化消息。
例如，您可以通过电子邮件发送下载链接(download link)，或者获得一个唯一的加密链接，用于复制和粘贴(copying and pasting)聊天消息。
付费专业计划(pro plan)（每月 12 美元或每年 120 美元）提供更多功能，例如 20GB 文件传输、100GB文件存储空间(file storage space)、文件传输的密码和到期日期，甚至可以设置和设计您自己的
WeTransfer 页面和 URL(WeTransfer page and URL) . 但除非您传输大型视频和音频文件，否则您的文件永远不可能超过 2GB。所以付费计划(paid plan)就足够了。
火狐发送(Firefox Send)
Firefox Send是我最近一直在尝试的另一个。Firefox Send由制作流行的(Firefox Send)网络浏览器(web browser)的同一个人带给(Brought)您，让 WeTransfer 物有所值。加上它显然受益于较高的知名度(name recognition)。
Firefox在(Firefox Send)WeTransfer上加大了赌注，无需注册即可传输 1GB 文件，如果您注册了免费帐户，则传输 2.5GB。一旦另一端的人下载了文件，链接就会自动过期，因此您不必担心链接被传递和您的文档被重新下载。但是，如果您使用Firefox 帐户(Firefox account)发送 2.5GB，您可以将这些链接保持长达一周的活动状态并(week and share)与更多人分享链接。
文件可以免费使用密码保护，文件上传后，您将获得加密链接。
升起(RiseUp)
与其他人相比，RiseUp在功能方面没有提供太多。此外，文件大小限制(file size limit)为区区 50MB。但是我过去使用RiseUp取得了巨大的成功，并且对于较小的文件很方便。
您只需将文件拖到窗口中，就会生成一个加密链接，该链接将持续一周。或者，如果其他人已经告诉您他们拥有该文件，您可以自己立即进入并删除该文件。
RiseUp也有一个粘贴文本部分(text section)，类似于PasteBin。因此，您可以将纯文本(plain text)复制并粘贴到站点中，并生成一个加密链接以将该文本发送给另一个人。
洋葱股(Onionshare)
Onionshare 之前我已经讨论过，所以我不会在这里深入研究它。但如果我没有将其包含在有关文件共享应用程序的文章中，那就太失职了。
Onionshare开始受到我的喜爱，因为与其他文件不同，您的文件不会存储在任何中央服务器上等待有人下载。相反，另一个人需要Tor 浏览器(the Tor Browser)，当两者都打开时，就会形成加密连接。然后文件会自动从您的计算机转到他们的计算机。
这称为点对点( (Peer)p2p(Peer) )，可能是最安全的传输形式。
一个等效的 P2P 平台是我即将试用的Resilio 。
信号(Signal)
我将通过提及我最喜欢的聊天程序(program –) ——Signal来结束这篇文章。Signal是一款极其安全的消息应用程序——有人说是有史以来最安全的。所以理论上通过Signal发送文件也非常安全。
在智能手机应用程序(smartphone app)上，点击您要将文件发送到的联系人。显然，这意味着他们也需要Signal 应用程序(Signal app)。然后点击左侧的“+”图标。
这将显示可以通过Signal(Signal)发送的内容列表
。在这种情况下，点击(Tap)“文档”。
下一步将您带到哪里获取文档取决于您使用的是iOS 还是 Android(iOS or Android)。在 iOS 上，它将是 iCloud Drive，因此请确保您的文件首先存在，然后只需在手机上导航到它。然后Signal(Signal)会将其发送给您的联系人。
如果您有Android 手机(Android phone)，我不确定您的文件需要放在哪里，因为我已经八年没有Android了。(Android)但我会想象你手机上的默认文件系统是什么。(default filing system)
5 Secure Online Services To Transfer Large Files To People
Aѕ email services stubbornly cling to their Web 1.0 25MB аttachment sіze limits, users meanwhile are needing ways to transfer larger and larger files.
Of course, if security is not an issue, there is always cloud storage or leaving files temporarily on your web domain. But if you need a secure way to transfer files across the Interwebs, you need something a bit safer.
The following are five secure file transfer options, which
are also free.
WeTransfer
As usual, we start with my favourite which was recommended to me two years ago. I love WeTransfer not only for its utter simplicity but also because of the fast uploading and downloading speed. I love things which “just work” and WeTransfer is always zippy and kicking butt.
There is a free option and a paid option. The free option
allows file transfers of up to 2GB without the need to register for an account.
Just upload the file, then add your own email and personalized message.
You can either send the download link by email or be given a
unique encrypted link for copying and pasting in chat messages for example.
The paid pro plan ($12 a month or $120 a year) offers a few
more features such as 20GB file transfers, 100GB file storage space, passwords
and expiry dates on your file transfers, and even set up and design your own
WeTransfer page and URL. But unless you are transferring large video and audio
files, your files are never likely to exceed 2GB. So the paid plan will
suffice.
Firefox Send
Firefox Send is another one I have been experimenting with lately. Brought to you by the same people who do the popular web browser, Firefox Send gives WeTransfer a serious run for its money. Plus it obviously benefits from the higher name recognition.
Firefox Send ups the ante on WeTransfer by making file
transfers 1GB without registration and 2.5GB if you register a free account.
Once the person at the other end downloads the file, the link automatically
expires so you don’t have to worry about links being passed around and your
documents being re-downloaded. But if you use a Firefox account to send 2.5GB,
you can keep those links active for up to a week and share the link with more
people.
Files can be password-protected free of charge and once the
file is uploaded, you are given your encrypted link.
RiseUp
Compared to the others, RiseUp does not offer so much in the way of features. Plus the file size limit is capped at a measly 50MB. But I have used RiseUp in the past to great success and is handy for smaller files.
You just need to drag your file into the window and an
encrypted link will be generated which will last for one week. Or if the other
person has already told you they have the file, you can go in and delete the
file yourself right away.
RiseUp also has a pasted text section, similar to PasteBin. So you can copy and paste plain text into the site and have an encrypted link generated to send that text to another person.
Onionshare
I have previously talked about Onionshare, so I am not going to delve too deeply into it here. But I would be remiss not to include it in an article about file sharing apps.
Onionshare is starting to gain my affections because unlike the others, your file is not stored on any central server waiting for someone to download it. Instead, the other person needs the Tor Browser and when both are open, an encrypted connection is formed. Then the file goes from your computer to theirs automatically.
This is called Peer to Peer (p2p) and is probably the most
secure form of transfer there is.
An equivalent P2P platform is Resilio which I am about to try out.
Signal
I am going to end this article by mentioning my favorite chat program – Signal. Signal is an extremely secure messaging app – some say the most secure ever. So theoretically sending files over Signal would also be extremely secure and safe.
On the smartphone app, tap on the contact you want to send
the file to. Obviously this means they need the Signal app too. Then tap the
“+” icon on the left.
This will bring up a list of things that can be sent via
Signal. Tap on “Document” in this case.
Where you are taken next for your document will depend on
whether you are on iOS or Android. On iOS, it will be iCloud Drive so make sure
your file is there first then simply navigate to it on your phone. Signal will
then send it to your contact.
If you have an Android phone, I am not sure where your file
would need to be as I haven’t had an Android for eight years now. But I would
imagine whatever the default filing system is on your phone.
