Hashdown link convert text into url hash, so you can open the link directly without the extra step to open a decoder
Example: https://hashdown.github.io/#SGFzaERvd24gTGluayBpcyBBd2Vzb21l
- The encoding and decoding are 100% done in client side javascript, our server never know your text. the url hash (what's after #) is never sent to the network.
- When the server is down, you can still decode the content from the url if you can find any Hashdown mirror site or an offline version of Hashdown tool.
- You can also use a password to protect your content.
Base2e15 convert text to unicode characters, each unicode character represents 15 bits of data.
Since Hashdown supports compression, it allows you to store more data in limited number of characters
Tadpole Code convert text to unicode combining characters, which is able to combine everything into "single" character.
Shadow Code convert text to ASCII control code, which is invisible in most browsers.
Wrap the input data with {} to hide part of the text, otherwise all text will be converted to Shadow Code
| Input | Output | |
|---|---|---|
| with{} | Hello{Hidden Text} World | Hello World |
| without{} | Hide All | >< |
When all text are hidden, >< is added to make it easier to copy paste.
