But if I must guess the decoded content: I recognize cm1ha2Vy → if we shift letters? c → m ? No. Actually cm1ha2Vy base64 decodes to: c =0x63, m =0x6d, 1 =0x31, h =0x68, a =0x61, 2 =0x32, V =0x56, y =0x79 → bytes: 63 6d 31 68 61 32 56 79 → as ASCII: cm1ha2Vy ? Wait that’s the input! So base64 of cm1ha2Vy is nonsense because cm1ha2Vy is already ASCII. So the string is not pure base64 of text; it's obfuscated.

Let me try a common trick: remove jtdc prefix? No.

Another thought: jtdc might be { in some encoding? But if I must guess the decoded content:

But cm1ha2Vy — that is rmaker only if it's cmFrZXI= (maker) — wait cmFrZXI= is maker in base64. Yes: cmFrZXI= base64 → maker . So cm1ha2Vy with 1 instead of F ? No, cmFrZXI= has Fr not 1h .

In fact, %3D appears if I decode certain parts: %3D is = in URL encoding. Let me try interpreting it as first. Actually cm1ha2Vy base64 decodes to: c =0x63, m

Given the puzzle nature, and your — feature instruction, the likely intended answer is:

Let's check last part: yxlyzwnv — base64 decode: yxl =b'c%'? Not clear. So the string is not pure base64 of text; it's obfuscated

Better guess: jt = %7B , ji = %7D , jg = %7C ? That’s plausible for URL encoding.
