Methods

decrypt(DecryptParameters, DecryptOptions)

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.

Microsoft recommends you not use CBC without first ensuring the integrity of the ciphertext using, for example, an HMAC. See https://learn.microsoft.com/dotnet/standard/security/vulnerabilities-cbc-mode for more information.

Example usage:

import { DefaultAzureCredential } from "@azure/identity";
import { KeyClient, CryptographyClient } from "@azure/keyvault-keys";

const credential = new DefaultAzureCredential();

const vaultName = "<YOUR KEYVAULT NAME>";
const url = `https://${vaultName}.vault.azure.net`;

const client = new KeyClient(url, credential);

const myKey = await client.createKey("MyKey", "RSA");
const cryptographyClient = new CryptographyClient(myKey.id, credential);

const encryptResult = await cryptographyClient.encrypt({
  algorithm: "RSA1_5",
  plaintext: Buffer.from("My Message"),
});
console.log("encrypt result: ", encryptResult.result);

const decryptResult = await cryptographyClient.decrypt({
  algorithm: "RSA1_5",
  ciphertext: encryptResult.result,
});
console.log("decrypt result: ", decryptResult.result.toString());
decrypt(string, Uint8Array, DecryptOptions)

Decrypts the given ciphertext with the specified cryptography algorithm

Example usage:

import { DefaultAzureCredential } from "@azure/identity";
import { KeyClient, CryptographyClient } from "@azure/keyvault-keys";

const url = `https://${vaultName}.vault.azure.net`;

const client = new KeyClient(url, credential);

const myKey = await client.createKey("MyKey", "RSA");
const cryptographyClient = new CryptographyClient(myKey.id, credential);

const encryptResult = await cryptographyClient.encrypt({
  algorithm: "RSA1_5",
  plaintext: Buffer.from("My Message"),
});
console.log("encrypt result: ", encryptResult.result);

const decryptResult = await cryptographyClient.decrypt({
  algorithm: "RSA1_5",
  ciphertext: encryptResult.result,
});
console.log("decrypt result: ", decryptResult.result.toString());
