My friend gave me this series of letters and I have no idea what it means: dxyne ikspu prspu xshzv fimse zmpvi zvert gtmco afbx
They also gave me these, but decided that the one listed above is the final and correct one:
qccbn jzhbg dngqw xvmnq zbtco oqyym adnza lvcet hpnec xdfhu uinpq vbaq ygeca bh
tnaus zzgab zlgzu gkpff edtgp ykbab bwzpi flpiy cap
And for some reason, a hint that seems completely useless: "decode".
I don't know if those will help at all, but I seriously can't figure this out. Maybe I'm overthinking this. It needs to be answered in the next 24 hours. Any help would be greatly appreciated. Thanks.
Fair disclaimer: my friend isn't the most "clean" person ever, so you have been warned. It could very well not be anything bad, though. I have no clue whatsoever.
