Usage

node-property-encryption.encrypt(toEncrypt, opts)

• toEncrypt <String> - string to encrypt
• opts <Object> - optional encrypt options

   opts.keyPath
   	- defaults to $home/.ssh/tc
   opts.outputEncoding
   	- (encoding of resulting encrypted string)
   	- defaults to base64

node-property-encryption.decrypt(toDecrypt, opts)

• toDecrypt <String> - string to encrypt
• opts <Object> - optional encrypt options

   opts.keyPath
   	- defaults to $home/.ssh/tc
   opts.outputEncoding
   	- defaults to base64

Key Generation

For unbiased generation, use ssh-keygen.

[~]$ cd ~/.ssh

[~/.ssh]$ ssh-keygen -b 4096
Generating public/private rsa key pair.
Enter file in which to save the key (/home/user/.ssh/id_rsa): tc
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in tc.
Your public key has been saved in tc.pub.
The key fingerprint is:
bc:9e:5e:6b:c3:e4:c4:5b:d9:1e:81:5d:43:fa:35:ad user@10.10.1.10
The key's randomart image is:
+--[ RSA 4096]----+
|              .. |
|              ..o|
|             + o+|

FOR ADMINISTRATORS

For generation of encrypted passwords / keys

### Clone Repository
$ git clone https://github.com/romanbalayan/node-property-encryption.git

### Enter directory
$ cd node-property-encryption

### Install npm dependency
$ npm install

### Run encrypt tool script
$ node tools/encrypt.js

? Enter Part #1: *****
? Re-enter Part #1: *****
Append another? Y
? Enter Part #2: *****
? Re-enter Part #2: *****
Append another? N

Encrypted Value: 9Nov5MRfn6Y=e/GrLGBb/CeX+YoiJPnp4Q==

In practice of "split knowledge", this tool shall allow each administrator to enter their part of the password/passcode/key and immediately confirm it.

The "Encrypted Value" output is the concatenated-then-encrypted value of all entered parts. It then can simply be copied-pasted to whichever key in config file/s it's applicable to.

FOR DEVELOPERS

### Install as dependency
$ npm install --save node-property-encryption

Do this for all config files with plaintext password.

1. require the node-property-encryption module
2. replace the plaintext password with function: decrypt('<encrypted-password>')

Sample old config/connection.js file

module.exports.connections = {
  userDb: {
    connectString: 'postgresql://localhost:5432/db',
    user: 'db_user',
    password: 'plain-text-password'
  }
};

Update the old config/connection.js file to:

const decrypt = require('node-property-encryption').decrypt;
module.exports.connections = {
  userDb: {
    connectString: 'postgresql://localhost:5432/db',
    user: 'db_user',
    password: decrypt('<encrypted password here>')
  }
};
