## Description

People said that base64 is an encoding, not an encryption. Did they have a misconception about that?
|

|
| 8 |
+
If you believe that base64 is just an encoding, then convince me that you are able to "decode" the article (which is in English).

有人話 base64 只係一個編碼而唔係一個密碼系統。佢哋個腦係咪出咗事?

如果你相信 base64 只係一個編碼嘅話,咁麻煩你將呢篇英文文章解碼啦。
