Crypto Challenge 1:

Sabbir loves electronics but he doesn’t know much about it so he asked for help from Kamrul.Kamrul good with electronics stuff. he started with basic logic gate after some time shafin join them and he knows some cool encryption bashed on logic gate. and he started explaining. by the help of kamrul and shafin now Sabbir know about electronics and also some cool encryption.

some cool step will give you the flag. Have Fun

Ciphertext : MjAyYzI3MDkyMDFmMDEzZDI1MTcwYjNjMjExMTExMDYxMjE5

Flag Format will be like EBD{*****........}

KEY : encryptbd

Hints : 1. basic decode(Base64), 2. in hex, 3. Try harder :wink:

the gate says

" if we give same input then output will be 0
" but if we not input same thing then the output will be 1"
