binhexa

By connecting with nc titan.picoctf.net 62817 it gives a series of 6 questions to perform operations on two binary numbers. The questions change each time, but in this case here are the numbers:

Binary Number 1: 11010100

Binary Number 2: 00100001

RapidTables has a good binary calculator that is used for most of the operators. Note: Be sure that both numbers are set to binary.

Operation 1: '&'

Perform the operation on Binary Number 1&2.

Result: 00000000

Operation 2: '|'

Perform the operation on Binary Number 1&2.

Enter the binary result: 11110101

Operation 3: '*'

Perform the operation on Binary Number 1&2.

Enter the binary result: 1101101010100

Operation 4: '<<'

Perform a left shift of Binary Number 1 by 1 bits.

Enter the binary result: 110101000

For bit shifting a bit shift calculator is easier to use. Note: Be sure to change the "Number Base" to Binary, the correct number referenced in the question, the correct directional shift operation, and the amount of bits to be shifted to 1 bit.

Operation 5: '+'

Perform the operation on Binary Number 1&2.

Enter the binary result: 11110101

Operation 6: '>>'

Perform a right shift of Binary Number 2 by 1 bits.

Enter the binary result: 10000

Enter the results of the last operation in hexadecimal:

For this, a Binary to Hex converter could be used. Specifically for the number "10000" in hex, it is 10. By entering that hex number the program gives the flag.
