Description

n8n-nodes-argon2

A n8n community node package for Argon2 hashing and verification.

Now includes two separate nodes for better workflow clarity:

• Argon2 Encrypt: Hash (encrypt) a string using Argon2id.
• Argon2 Verify: Verify a string against an Argon2 hash, with two outputs: true and false.

Features

• Argon2 Encrypt Node

  • Input: Plain text (Text)
  • Output: { "hash": "..." } (single output)

• Argon2 Verify Node

  • Inputs: Text and Hash
  • Output branches:
    • true: If the verification is successful ({ "match": true })
    • false: If the verification fails or errors ({ "match": false } or { "match": false, "error": "..." })

Installation

Using n8n Community Nodes (Recommended)

1. Go to Settings → Community Nodes in your n8n instance.
2. Click Install and search for n8n-nodes-argon2.
3. Install and restart n8n if required.

Manual (Development)

npm install n8n-nodes-argon2

Usage

Argon2 Encrypt

• Add the Argon2 Encrypt node to your workflow.
• Provide the Text to hash.
• The output will be:

  { "hash": "$argon2id$..." }
  

Argon2 Verify

• Add the Argon2 Verify node to your workflow.
• Provide the Text and the Hash to check.
• The node will route the result:
  • If the verification is successful, the output will be sent by the true output:

    { "match": true }
    

  • If the verification fails or there is an error, the output will be sent by the false output:

    { "match": false }
    { "match": false, "error": "<error message>" }
    

Example

Encrypt

• Input: mySecretPassword
• Output:

  { "hash": "$argon2id$v=19$m=4096,t=3,p=1$..." }
  

Verify

• Input: mySecretPassword, $argon2id$v=19$m=4096,t=3,p=1$...
• Output (true branch):

  { "match": true }
  

• Input: wrongPassword, $argon2id$v=19$m=4096,t=3,p=1$...
• Output (false branch):

  { "match": false }
