Answer: Secret Code #111

The secret message says:

ORANGE

The shift was 4.

Letter by letter

Secret letter	E	I	K	R	S	V
Real letter	A	E	G	N	O	R

Decode it with Python

This program does the decoding for you. Change the secret and the shift to crack other messages!

secret = "SVERKI"
shift = 4
message = ""

for letter in secret:
    if letter.isalpha():
        number = (ord(letter) - ord("A") - shift) % 26
        message = message + chr(number + ord("A"))
    else:
        message = message + letter

print(message)

When you run it, it prints:

ORANGE
