today I found myself in front of the following codified text:
MzIgVCA2NTg3MjYgNDg1MTY0Nw0KMzIgVCA2NTc5OTkgNDg1MzExMw0KMzIgVCA2NTc0MDUgNDg1MjMxM A0KMzIgVCA2NTg2MzkgNDg1MTgzMg0KMzIgVCA2NTc1NDIgNDg1MzY4NA0KMzIgVCA2NTgwMTMgNDg1MTQ 0Nw0KMzIgVCA2NTc3MzMgNDg1MzMxNQ0KMzIgVCA2NTcyMjggNDg1MzM0Mw0KMzIgVCA2NTc4NDggNDg1 MTY3OA==
I know that the text is composed of geographic coordinates.
and that the text: "MzIgVCA2NTc0MDUgNDg1MjMxM A0KMzIgVCA2NTg2MzkgNDg1MTgzMg0KMzIgVCA2NTc1NDIgNDg1MzY4NA"
corresponds to the coordinates:
32 T 657405 4852310
32 T 658639 4851832
32 T 657542 4853684
MzIgVCA2 NT c0MDU gND g1M jMxMA 0K -> 32 T 657405 4852310
MzIgVCA2 NT g2Mzk gND g1M TgzMg 0K -> 32 T 658639 4851832
MzIgVCA2 NT c1NDI gND g1M zY4NA 0K -> 32 T 657542 4853684
what is the encryption key?
