Conversions in Ruby

While working with exploits and modules, we will require tons of conversion operations. Let's see some of the conversions we will use in the upcoming sections:

• Hexadecimal to decimal conversion:
  • It's quite easy to convert a value to a decimal from a hexadecimal in Ruby using the inbuilt hex function. Let's look at an example:

irb(main):021:0> a= "10"
=> "10"
irb(main):022:0> a.hex
=> 16

• • We can see we got the value 16 for a hexadecimal value of 10.
• Decimal to hexadecimal conversion:
  • The opposite of the preceding function can be performed with the to_s function, as follows:

irb(main):028:0> 16.to_s(16)
=> "10"
