Abstract

o pedido fornece um método de codificação de dados binários, em que o método compreende: obter dados binários que têm um comprimento de k bytes, em que k é um número natural, e usar um algoritmo de codificação predeterminado para converter os k bytes dos dados binários em (k+t) bytes de dados codificados de 7 bits, em que t é um número inteiro mínimo maior que ou igual a k/7. a solução técnica no pedido pode gerar um arquivo codificado que tem um comprimento menor que o de um arquivo codificado de base64, que requer menos tráfego de dados em transmissão de rede, e que é adequado para um cenário de aplicação que tem requisitos estritos.
