Should you encrypt emails?
你應該加密電子郵件嗎？ (Should you encrypt emails? Should you encrypt emails?)
Yes, because e-mails offer the same protection against “reading” as the good old postcard. If you want/need to send really confidential data, such as business data, by e-mail, you cannot avoid encryption. The following options are available to protect messages/documents.
Password-protected files:
You can of course put the data in a password-protected file and then attach it to the e-mail. The only thing is that it is not very convenient to use and confidential things written in the message can still be read. The password should at least be sent by another means (messenger, telephone, etc.) and not by e-mail.
PGP (Pretty Good Privacy)
PGP uses a so-called public key procedure in which there is a uniquely assigned key pair. PGP is based on the so-called Web of Trust, in which there is no central certification authority, but trust is managed by the users themselves. Setting this up is much more difficult and presents many users with major hurdles.
是的，因為電子郵件提供與舊明信片相同的防止“閱讀”的保護。 如果您想/需要通過電子郵件發送真正機密的數據，例如業務數據，則無法避免加密。 以下選項可用於保護消息/文檔。
受密碼保護的文件：
您當然可以將數據放入受密碼保護的文件中，然後將其附加到電子郵件中。 唯一就是使用起來不是很方便，而且郵件裡寫的機密的東西還是可以看的。 密碼至少應通過其他方式（信使、電話等）而不是通過電子郵件發送。
PGP（相當好的隱私）
PGP 使用所謂的公鑰程序，其中有一個唯一分配的密鑰對。 PGP 基於所謂的信任網絡，其中沒有中央證書頒發機構，但信任由用戶自己管理。 設置起來要困難得多，並且給許多用戶帶來了重大障礙。
