htmlvault now contains the encryption part of the package, so {encryptedRmd} can focus on the rmd part.

Not sure, why the whole project is classified as html ...

Hi, this is a very useful package!
When I use it with a htmlwidget created with the visNetwork package the widget is not displayed in the browser when decrypted. Short example below.

---
title: "test_enrcrypytedRmd"
output: encryptedRmd::encrypted_html_document
---

```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = TRUE)
```

```{r results='asis'}
library(visNetwork)
nodes <- data.frame(id = 1:3)
edges <- data.frame(from = c(1,2), to = c(1,3))

visNetwork(nodes, edges)
```

In most cases .Rmd is self including, so if you insert an image, it will use data URI scheme. That means everything is inside one .html file, so an encrypting/decrypting process with encryptedRmd goes well.

There are also possibility to have relative paths, so an encrypting/decrypting process with encryptedRmd goes well, but files with relative paths are not included in it.

Here is an example.

I used the version 0.2.09

Is it possible to run encrypt_html() function with a folder?

Is there a way to encrypt files with a known key and not a randomly generated one?

I'm able to encrypt an HTML file using encryptedRmd:

library(encryptedRmd)

path = '//R_Scripts/test.html'

encrypt_html_file(
  path,
  output_path = paste0(path, ".enc.html")
)

The encryption works, and I can access the new encrypted HTML. However, none of the ggplots show up in the encrypted version. Tables with data do show up. The test.html document has ggplots that appear perfectly.

Thanks!

With a JS pdf viewer like Mozilla's pdf.js that would be possible.

This would then allow human entered passwords that are not perfectly random.

However the node packages does not support that at the moment

I forgot to add them

Could it be possible to specify a custom decryption page? This would enable people to provide:

• Different languages
• Contact details
• Branding

Superb package, I'm really looking forward to using it.

Hi, great package! Is there a way to add an option after entering the key, so it opens the html to the current browser page rather than downloading the html file?

It would be great if another pair of eyes could look at the security of the package. In particular the encryption.

Relevant lines are here (only 3: key, nonce and encrypt):

For decryption, the JS code is in devel. However IMHO encryption is the most critical part. The JS code is only used for decryption purposes.

Hi,

When I run encrypt_html_file with the file path to the html doc I want to protect, R immediately crashes. I've tried with the CRAN version and GitHub Master. My html file contains a leaflet map (leaflet package) which has some interactive features - i.e. you can click on a an area of the map and a popup appears. If I remove the map from the html doc it encrypts fine. Any workarounds available?

Thanks

Hi,

Thank you for your package.

I just tried it and I got an error:

Error: segfault from C stack overflow

Any clues if it is related to the new R 4.1.0 version? I am using a Mac mini Intel, 11.3.1 macOS. The file to be encrypted is about 10 MB.

Best, RN.

Loving the simplicity of this! However, it is not rendering Plotly interactive graphs, which I assume has to do with some way it renders javascript. Any ideas?
