Decryption of png, how?

Post by Sorwidir »

Trying to decrypt a png file, the header of my png starts like this:

Code: Select all

53 23 54 24 4f 25 53 6b 00 00 02 04 e9 bd d1 f4
b7 f1 85 63 b6 53 b4 ab 40 f2 58 47 9a af 2a a9
83 94 aa 69 f7 6f 04 18 b6 d2 ba 83 1a 1e ac cd
9f 45 28 47 c2 55 f0 5b 9d 53 ea b1 44 85 36


I tried different codes and decryption algorithms but to no luck. Does anyone have a clue? I'll attach the file below (and another one, if you can compare or see any differences, not sure if that will help though but both seem to be encrypted)

files: attachment

From what I have noticed, is that EVERY png starts with this header:
