secretvaults

Wrapper classes for simplifying usage of Nillion's Secret Vault and the nilQL encryption and decryption library.

Installation

npm install secretvaults

NilQLWrapper: Lightweight wrapper for encryption and decryption using nilQL:

• Encrypts data into shares for distributed storage across nodes
• Handles structured data with '%allot' markers for selective encryption
• Recombines shares and decrypts data marked %share using unify
• Manages secret keys for encryption/decryption operations
• Recombines and decrypts shares to recover original data
• Maintains compatibility with SecretVault timestamps
• No node configuration required when used standalone

SecretVaultWrapper: wrapper for Secret Vault API operations:

Authentication

• Handles JWT creation and management per node
• Manages node authentication automatically

Schema Operations

Create: Deploy schema across nodes (/api/v1/schemas)

• Creates schemas with optional custom ID
• Validates schema structure
• Distributes to all nodes

Read: List available schemas (/api/v1/schemas)

• Retrieves schema configurations
• Shows schema metadata and structure

Delete: Remove schema definition (/api/v1/schemas)

• Deletes schema across all nodes
• Preserves data integrity

Data Operations

Write: Upload data to the specified schema collection (/api/v1/data/create)

• Writes data to multiple nodes
• Encrypts specified fields with '%allot' markers before distribution
• Distributes encrypted shares marked %share across nodes

Read: Retrieve data from the specified schema collection that matches the provided filter (/api/v1/data/read)

• Retrieves data from all nodes
• Recombines encrypted shares marked %share from nodes to decrypts specified fields automatically
• Returns decrypted record

Flush: Remove all documents in a schema collection (/api/v1/data/flush)

• Removes all data across nodes from a schema collection

List the organization's schemas (/api/v1/schemas)

Usage

Standalone NilQLWrapper Example

Run examples

node examples/nilQlEncryption.js

SecretVaultWrapper Example

Copy the .env.example to create a .env file that uses the example org

cp .env.example .env

Run example to encrypt and upload data to all nodes, then read data from nodes.

node examples/store/readWriteSv.js

Basic setup

const secretVaultCollection = new SecretVaultWrapper(
    orgConfig.nodes,
    orgConfig.orgCredentials,
    collectionConfig.schemaId
);
await secretVaultCollection.init();

// years_in_web3 field value is marked with '%allot' to show it will be encrypted
const dataWritten = await secretVaultCollection.writeToNodes(
    [{
        _id: uuidv4(),
        years_in_web3: { '%allot': 4 },
        responses: [
        { rating: 5, question_number: 1 },
        { rating: 3, question_number: 2 },
        ],
    },]
);
