Node red Crypto utilities

Overview

Some nodes that wrap Node.js Crypto.

AES

Algorithm: aes-256-cbc

encrypt

input (msg.paylaod):

{
	"key": <string> | <ArrayBuffer> | <Buffer> | <TypedArray> | <DataView> | <KeyObject> | <CryptoKey>,
	"data": <Buffer>
}

output:

{
	"encryptedData": <Buffer>,
	"initVector": <Buffer>
}

decrypt

input (msg.paylaod):

{
	"key": <string> | <ArrayBuffer> | <Buffer> | <TypedArray> | <DataView> | <KeyObject> | <CryptoKey>,
	"data": <Buffer>
	"initVector": <Buffer>
}

output:

	"payload": <Buffer>,

RSA

encrypt

input (msg.paylaod):

{
	"publicKey": <string> | <ArrayBuffer> | <Buffer> | <TypedArray> | <DataView> | <KeyObject> | <CryptoKey>,
	"data": <string> | <ArrayBuffer> | <Buffer> | <TypedArray> | <DataView> | <object>
}

output:

	"payload": <cBuffer>

decrypt

input (msg.paylaod):

{
	"privateKey": <string> | <ArrayBuffer> | <Buffer> | <TypedArray> | <DataView> | <KeyObject> | <CryptoKey>,
	"data": <Buffer>
}

output:

	"payload": <Buffer>,

SHA256

input (msg.paylaod):

	"payload": <string> | <ArrayBuffer> | <Buffer> | <TypedArray>

output:

	"payload": <Buffer>,
