n8n-nodes-bcryptjs

This is an n8n community node that allows you to use bcryptjs for password hashing and verification operations in your n8n workflows.

n8n is a fair-code licensed workflow automation platform.

Installation • Operations • Usage Examples • Resources

Installation

Follow the installation guide in the n8n community nodes documentation.

Community Nodes Installation

1. In n8n, go to Settings > Community Nodes.
2. Select Install.
3. Enter @luka-cat-mimi/n8n-nodes-bcryptjs in the npm Package Name field.
4. Agree to the risks, then select Install.

After installation, the Bcryptjs node will appear in the Cryptography category.

Manual Installation

To install the node locally, you can use npm package manager:

# For n8n self-hosted
npm install @luka-cat-mimi/n8n-nodes-bcryptjs

Operations

This node provides all bcryptjs async function capabilities:

Supported Operations

Operation	Description
Compare Password	Asynchronously compare password with hash
Generate Salt	Asynchronously generate salt value
Get Rounds	Get the number of rounds used in the hash
Get Salt	Extract salt portion from hash
Hash Password	Asynchronously hash password
Test Truncation	Test if password will be truncated (over 72 bytes)

Parameter Descriptions

Generate Salt

• Rounds: The cost of processing the data, default value is 10
• Minor Version: The minor version of bcrypt, 'a' or 'b', default is 'b'

Hash Password

• Password: The password to hash
• Salt or Rounds: Salt value to use for hashing, or number specifying rounds

Compare Password

• Password: The original password to compare
• Hash: The hash value to compare against the password

Get Rounds

• Hash: The hash value to extract rounds from

Get Salt

• Hash: The hash value to extract salt from

Test Truncation

• Password: The password to check

Options

• Output Field Name: Field name where the result will be saved, default is 'result'

Usage Examples

Example 1: Password Hashing

Hash passwords when creating users:

1. Set operation to Hash Password
2. Enter the password to hash
3. Set rounds (recommended 10-12)
4. The node will return the hashed password

Input:

{
  "password": "mySecretPassword"
}

Output:

{
  "password": "mySecretPassword",
  "result": "$2b$10$N9qo8uLOickgx2ZMRZoMye..."
}

Example 2: Password Verification

Verify passwords during user login:

1. Set operation to Compare Password
2. Enter the original password and stored hash value
3. The node will return true or false

Input:

{
  "password": "mySecretPassword",
  "hash": "$2b$10$N9qo8uLOickgx2ZMRZoMye..."
}

Output:

{
  "password": "mySecretPassword",
  "hash": "$2b$10$N9qo8uLOickgx2ZMRZoMye...",
  "result": true
}

Example 3: Custom Output Field

Set a custom output field name in options:

1. Expand the Options section
2. Set Output Field Name to hashedPassword
3. The result will be saved to the specified field

Output:

{
  "password": "mySecretPassword",
  "hashedPassword": "$2b$10$N9qo8uLOickgx2ZMRZoMye..."
}

Security Considerations

• bcrypt only uses the first 72 bytes of a password, any extra bytes are ignored
• Recommend using async version to avoid blocking the event loop
• Higher rounds mean better security but longer processing time
• Default rounds of 10 is secure for most cases
• Production environments should consider using 12 rounds or higher
