Encrypt Another Character Highlight the cell range A1:K9. Copy this range. Click cell A11 and paste the copied range. Within the newly pasted section of your worksheet, change the given character from "H" to "E" and apply the procedure of STEP 2 to determine the cipher character equivalent to the letter "E". Repeat this procedure until you encrypt the four characters in the word "HELP". Use an ASCII chart of characters to assist you, if necessary. Note: keep the same key for each of the letters in "HELP".
