Answer:
The offset
Explanation:
In the question, we understand that the original text is HELLO and the encrypted text is OLSSV.
It should be noted that O replaced H, L replaced E, S replaced L and V replacement O.
This is made possible by a term refered to as offset.
The offset is used to determine the character that will replace another when it is encrypted.
7 characters after H is O; this is same for every other characters in the text.
