decoding ciphertext
ciphertext = "Xwx8BGL9VRp3VQqXD0Z0VQ85BQAYCmuUDG9XFw0tDGAYDmptCmttLS80FlN/ZxVtBm9WEmWSVQ84VTD/FlN7EmuTZmx4VQ8lVQ9XCmMYKD=="
Hint: r3 r7 b4 r3
Meaning:
r3 = ROT13
r7 = ROT47
b4 = Base64
Apply ROT13 to the ciphertext.
Base64 decode the result
Apply ROT47 to the decoded text
Apply ROT13 again
output is your original text : Luxury is sleep automatically comes at 10pm and waking at 5am without an alarm.
