Cryptohack rsa writeup
WebCryptosystems like RSA works on numbers, but messages are made up of characters. How should we convert our messages into numbers so that mathematical operations can be applied? The most common way is to take the ordinal bytes of the message, convert them into hexadecimal, and concatenate.
