Got a string in JSON, definitly encoded. The question is: if there any way to find out which method's been used to encode it an how to make it readable again?

#2aHR0cDovL2RhdGEtaGQuZGF0YWxvY2sucnUvZmkybG0vYS8vNDQwMjg1L2hkX1RoZS5XYWxraW5nLkRlYWQuUzExRTAwLjcyMHAucnVzLkxvc3RGaWxtLlRWLmExLjE2LjExLjIyLm1wNCBvciBodHRwOi8vdGVtcC1jZG4uZGF0YWxvY2sucnUvZmkybG0vYS8vNDQwMjg1LzdmX1RoZS5XYWxraW5nLkRlYWQuUzExRTAwLjcyMHAucnVzLkxvc3RGaWxtLlRWLmExLjE2LjExLj\/\/b2xvbG8=IyLm1wNA==

The whole object looks like:

  • Could be base64 (RFC 2045 variant, so many online decoders will not accept it), but the result does not look familiar to me. Is there no documentation of what is supposed to be in that JSON string? – harold Nov 23 '22 at 14:20
  • it should be a link to a file – AlexNasonov Nov 23 '22 at 14:38
  • It doesn't look like a link, it looks like it could be the file though, was this part of a data url? – harold Nov 23 '22 at 14:48
  • no.. the whole object looks like: {"title":"1 \u0441\u0435\u0440\u0438\u044f SD

  • I can't really make anything of it then, best I could do is decode it to 225 bytes starting with `0xD9, 0xA1, 0xD1, 0xD1, 0xC0, 0xE8, 0xBC, 0xBD, 0x91, 0x85, 0xD1, 0x84, 0xB5, 0xA1, 0x90, 0xB9` (too long to post the whole thing) which I don't recognize the format of – harold Nov 23 '22 at 15:03
