Desert Scroll is an old project of mine which i wrote in perl couple of years ago
and basicly its an implementation of a Book encryption

Loading && Mapping the key file:
at first before every encryption/decryption of plain text a key is being loaded into the memory of the script/program and then mapped into a bi-dimensional array while the first dimension is used to map all ASCII numeric values that exists in the key and in the second dimension there are all the offsets of the same ASCII value which exists in the key file

Encrypting process:
the process of the encryption is basicly a replacment of the original characters in the plaintext with the one of the offsets which lays under that ASCII value in the array
its worth mentioning that no addition steps has been taken to camouflage and prevent from the third side to understand the mechanisem of this encryption
