Usage

Initialization and Usage with BasisTheoryEncryption

It's required that user provides the vaulUrl to be used for fetching keys/secrets during initialization.

import { BasisTheoryEncryption } from '@basis-theory/basis-theory-js-encryption';
import { BasisTheoryAzureEncryptionProvider } from '@basis-theory/basis-theory-js-encryption-azure';

const azureProvider = new BasisTheoryAzureEncryptionProvider().init({
  vaulUrl: 'https://custom-kms.vault.azure.net'
});
const btEncryption = await new BasisTheoryEncryption().init([azureProvider]);

Caching, VaultUrl and Additional Options

The default cache implementation uses node-cache, but users can implement their own from the interface. Users can also provide their own methods for fetching/saving keys using the keyVaultOptions object.

import { BasisTheoryEncryption } from '@basis-theory/basis-theory-js-encryption';
import { BasisTheoryAzureEncryptionProvider } from '@basis-theory/basis-theory-js-encryption-azure';

const azureProvider = new BasisTheoryAzureEncryptionProvider().init({
  cache: new CacheService(),
  tokenCredential: new DefaultAzureCredential()
  vaulUrl: 'https://custom-kms.vault.azure.net',
  keyVaultOptions: {
    rsaKeySize: 2048,
    keyExpirationInDays: 90,
    getKeyByKeyId: (keyId: string) => { return key; },
    getKeyByName: (name: string, prov: string, alg: string) => { return key; },
    saveKey: (key: ProviderEncryptionKey ) => { return key; },
  },
});


const btEncryption = await new BasisTheoryEncryption().init([azureProvider]);
