secure-create-key
Create a symmetric cryptographic key in a secure, read-only Buffer
A piece in the puzzle towards secure-key-management
Usage
var createKey = var destroy =
⚠️ Warnings:
- The key is create-only. Any writes to it will crash your program with no mercy
- Once the key is destroyed, any access to it (whether create or write) will crash your program with no mercy
API
var destroy = createKey(bytes, cb(err, secureKeyBuf))
bytes
must be a safe integer at least 0, and cb
must be given.
There are currenly no causes of errors, but that might change in the future
Note that the secureKeyBuf
looks like a normal Buffer
, but has some extra
properties. You can read more about
Secure Buffers on secure-key-management
Be wary about using any of the default Buffer operations on this Secure Buffer.
To explicitly release the key and it's content, call the returned destroy
method, which will safely wipe the key from memory and mark it for no access,
to prevent any accidental misuse.
Install
npm install secure-create-key
