Construtores

CryptographyClient(JsonWebKey)

Constrói uma nova instância do cliente cryptography para a chave fornecida no modo local.

Métodos

decrypt(DecryptParameters, DecryptOptions)

Descriptografa o texto criptografado especificado com os parâmetros de descriptografia especificados. Dependendo do algoritmo usado nos parâmetros de descriptografia, o conjunto de possíveis parâmetros de descriptografia será alterado.

A Microsoft recomenda que você não use CBC sem primeiro garantir a integridade do texto criptografado usando, por exemplo, um HMAC. Consulte https://learn.microsoft.com/dotnet/standard/security/vulnerabilities-cbc-mode para obter mais informações.

Uso de exemplo:

import { DefaultAzureCredential } from "@azure/identity";

});
console.log("encrypt result: ", encryptResult.result);

const decryptResult = await cryptographyClient.decrypt({

  ciphertext: encryptResult.result,
});
console.log("decrypt result: ", decryptResult.result.toString());
