Hexadecimal tools

For a given string of Hexadecimal, list out the frequencies of various hex combinations. This can be useful when looking at data-driven puzzles, and trying to find recognizable patterns.

The dropdown allows you to select a delimiter, which is how your hex values are split up and joined together. The default is a space, you can select no delimiter if your hex contains no spaces. This will default the split to every 2 characters. Negative numbers are allowed.

Unlike reversing the entire string where 48 65 6c 6c 6f [Hello] becomes f6 c6 c6 56 84, here we have some unique ways to reverse hex strings.

Reverse bytes

This reverses the order of bits within each byte. 48 65 6c 6c 6f becomes 84 56 c6 c6 f6

Reverse byte order

While it sounds similar, byte order is a little different. This reverses the order of each hex byte in the string, so 48 65 6c 6c 6f becomes 6f 6c 6c 65 48

Reverse nibbles

This reverses the bits within each nibble (4 bits) of every byte in a hexadecimal string, which is equivalent to: converting the hex string to binary, reversing the bits in each nibble, then converting it back to hexadecimal. 48 65 6c 6c 6f becomes 21 6A 36 36 F6

The delimiter dropdown allows you to select a delimiter, which is how your hex values are split up and joined together. The default is a space, you can select no delimiter if your hex contains no spaces. This will default the split to every 2 characters.

Lazy shift a hexadecimal string up or down: 48 65 6c 6c 6f [Hello] becomes 49 66 6d 6d 70 [Ifmmp] when shifted 1 to the right (+1) or 47 64 6b 6b 6e [Gdkkn] when shifted 1 to the left.

The delimiter dropdown allows you to select a delimiter, which is how your hex values are split up and joined together. The default is a space, you can select no delimiter if your hex contains no spaces. This will default the split to every 2 characters. Negative numbers are allowed.
