Cómo saber si a bunch of chars es un texto base64 encoded?

TLDR; tiene uno o varios '=' al final de la secuencia

Por contrucción, el string de base64 enconding tiene que tener una logitud múltiplo de 4. Si la logitud del texto enconded no es múltiplo de 3 se debe agregar padding para que la salida sea múltiplo de 4.

Ej extraido de wikipedia

| Input | Length | Outout | Length | Padding |
