mini web app to use WebCrypto
|
||||
|
||||
<a href="javascript: win=window.open('','','titlebar=no,location=no'); fetch('https'+'://git.p2p.legal/dig/kriptopter/raw/master/kriptopter').then(res=>res.text()).then(app=>win.document.write(app) ))">bookmarklet</a>
|
||||
|
||||
## Install
|
||||
|
||||
```
|
||||
git clone https//git.p2p.legal/dig/kriptopter
|
||||
```
|
||||
|
||||
## Usage
|
||||
|
||||
### Standalone
|
||||
Open the file `kriptopter` in a browser.
|
||||
_(Tested only under Iron/Chromium 63.0.3300.0, please do the test in other browser and submit an issue, with a minimum stack trace, if you want to help )_
|
||||
|
||||
### Bookmarklet
|
||||
|
||||
To compile the app to be used as `javascrip:` url in a bookmark, some characters need to be escaped,
|
||||
you can use `kompilo.js` with nodejs:
|
||||
```javascript
|
||||
node kompilo
|
||||
```
|
||||
it will generate a `kriptoptlet` file containing the text to copy/paste in a new bookmark.
|
||||
|
||||
<a href="javascript: win=window.open('','','titlebar=no,location=no'); fetch('https'+'://git.p2p.legal/dig/kriptopter/raw/master/kriptopter').then(res=>res.text()).then(app=>win.document.write(app) ))">bookmarklet online</a>
