Package version
Constructs a new instance of the Cryptography client for the given key
Example usage:
import { KeyClient, CryptographyClient } from "@azure/keyvault-keys";
import { DefaultAzureCredential } from "@azure/identity";
let vaultUrl = `https://<MY KEYVAULT HERE>.vault.azure.net`;
let credentials = new DefaultAzureCredential();
let keyClient = new KeyClient(vaultUrl, credentials);
let keyVaultKey = await keyClient.getKey("MyKey");
let client = new CryptographyClient(keyVaultKey.id, credentials);
// or
let client = new CryptographyClient(keyVaultKey, credentials);The key to use during cryptography tasks. You can also pass the identifier of the key i.e its url here.
An object that implements the TokenCredential interface used to authenticate requests to the service. Use the @azure/identity package to create a credential that suits your needs.
Pipeline options used to configure Key Vault API requests. Omit this parameter to use the default pipeline configuration.
Constructs a new instance of the Cryptography client for the given key in local mode.
Example usage:
import { CryptographyClient } from "@azure/keyvault-keys";
const jsonWebKey: JsonWebKey = {
// ...
};
const client = new CryptographyClient(jsonWebKey);The key to use during cryptography tasks. You can also pass the identifier of the key i.e its url here.
The ID of the key used to perform cryptographic operations for the client.
The base URL to the vault. If a local JsonWebKey is used vaultUrl will be empty.
Decrypts the given ciphertext with the specified decryption parameters. Depending on the algorithm used in the decryption parameters, the set of possible decryption parameters will change.
Example usage:
let client = new CryptographyClient(keyVaultKey, credentials);
let result = await client.decrypt({ algorithm: "RSA1_5", ciphertext: encryptedBuffer });
let result = await client.decrypt({ algorithm: "A256GCM", iv: ivFromEncryptResult, authenticationTag: tagFromEncryptResult });The decryption parameters.
Additional options.
Decrypts the given ciphertext with the specified cryptography algorithm
Example usage:
let client = new CryptographyClient(keyVaultKey, credentials);
let result = await client.decrypt("RSA1_5", encryptedBuffer);The algorithm to use.
The text to decrypt.
Additional options.
Encrypts the given plaintext with the specified encryption parameters. Depending on the algorithm set in the encryption parameters, the set of possible encryption parameters will change.
Example usage:
let client = new CryptographyClient(keyVaultKey, credentials);
let result = await client.encrypt({ algorithm: "RSA1_5", plaintext: Buffer.from("My Message")});
let result = await client.encrypt({ algorithm: "A256GCM", plaintext: Buffer.from("My Message"), additionalAuthenticatedData: Buffer.from("My authenticated data")});The encryption parameters, keyed on the encryption algorithm chosen.
Additional options.

Example usage:
let client = new CryptographyClient(keyVaultKey, credentials);
let result = await client.sign("RS256", digest);The signing algorithm to use.
The digest of the data to sign.
Additional options.
Cryptographically sign a block of data
Example usage:
let client = new CryptographyClient(keyVaultKey, credentials);
let result = await client.signData("RS256", message);The signing algorithm to use.
The data to sign.
Additional options.
Unwraps the given wrapped key using the specified cryptography algorithm
Example usage:
let client = new CryptographyClient(keyVaultKey, credentials);
let result = await client.unwrapKey("RSA1_5", keyToUnwrap);The decryption algorithm to use to unwrap the key.
The encrypted key to unwrap.
Additional options.
