# Chaves válidas para operações criptográficas
Certas chaves podem ser usadas apenas para operações específicas. Além disso, algumas operações podem limitar os principais modos de uso das chaves. Consulte a tabela a seguir para ver as combinações permitidas.
**nota**
Certas combinações, embora permitidas, podem criar situações inutilizáveis, como gerar códigos CVV `(generate)`, mas não conseguir verificá-los `(verify)`.

## Gerar/verificar MAC
As chaves MAC são usadas para criar hashes criptográficos message/body de vários dados. Não é recomendável criar uma chave com modos de uso limitados, pois você não conseguirá realizar a operação correspondente. No entanto, você pode usar import/export uma chave com apenas uma operação se o outro sistema for destinado a executar a outra metade do par de operações.

## GenerateMacEmvPinChange
GenerateMacEmvPinChange combina geração de MAC e criptografia de PIN para operações de alteração de PIN offline do EMV. Essa operação requer dois tipos de chave diferentes: uma chave de integridade para geração de MAC e uma chave de confidencialidade para criptografia de PIN.
