For example, there is arbitrary text where sequences can occur that are encoded in base64.

Is it possible to get all these sequences from the text in some regular way?

As I understand it, sometimes it happens with the use of spaces => you need to understand that 2 sequences that are separated by a space refer to the same coded information.

  • Well, hmm. For example, the text Rindfleischetikettierungsueberwachungsaufgabenuebertragungsgesetz is base64 or not? (This is a German word, in general.) - VladD

    Any sequence of 4 characters allowed in BASE64 can be decoded as 3 bytes. - PetSerAl

    You can try to make a frequency analysis - Anton Shchyrov
