### YEncoder
2023-06-06 18:56:34 +00:00
O YEncoder é um algoritmo de codificação que converte dados binários em ASCII. Ele é usado para codificar e-mails, arquivos e outras informações que precisam ser transmitidas em formato de texto. O YEncoder é semelhante ao Base64, mas usa um conjunto de caracteres diferente para representar os dados. Para decodificar dados codificados com YEncoder, você pode usar uma ferramenta online ou um script Python.

### BinHex
2023-06-06 18:56:34 +00:00
BinHex é um método de codificação de arquivos binários em ASCII para que possam ser enviados por e-mail. É semelhante ao Uuencode, mas é mais antigo e menos comum.

### ASCII85
2023-06-06 18:56:34 +00:00
ASCII85 é um formato de codificação de dados que permite representar dados binários em ASCII. É semelhante ao Base64, mas é mais eficiente em termos de espaço. É comumente usado em PDFs e PostScript.
