secure-rm

Completely erases files by making recovery impossible.

❓ Why

When you delete a file using the rm command or fs.unlink in node, it only removes direct pointers to the data disk sectors and make the data recovery possible with common software tools.

Permanent data erasure goes beyond basic file deletion commands, which:

• Allow for selection of a specific standard, based on unique needs,
• Verify the overwriting method has been successful and removed data across the entire device.

📦 Installation

Node and npm required.

npm install secure-rm

🚀 Getting started

If you want your application to delete specific files with a pass of cryptographically strong pseudo-random data, use one of these code snippets:

Callback version

const srm = require('secure-rm')

srm('./folder/*.js', (err) => {
  if (err) throw err
  console.log('Files successfully deleted !')
})

Promise version

const srm = require('secure-rm')

srm('./folder/*.js')
  .then(() => console.log('Files successfully deleted !'))
  .catch((err) => {throw err})
