I guess something like this should work:

packager-win-x64.exe in=C:\shaka-packager\master-03028928be-1702995022883.en.m4a,stream=audio,output=C:\shaka-packager\WhatIf01.m4a --enable_raw_key_decryption --keys key_id=b3af32f237be4b24d053256eb57f4294:key=3617bd30da9cd5fa39328235fb49155a,key_id=aa46933d36476da7c869df1b39429898:key=a7834a02f23b750f679a8b708214047b,key_id=e16c8e7126666089b531168f98cc4406:key=425ee14a0e3a5c30e040341e985389ee

Or just try the key pairs one at a time.

Thanks but it says packaging error 8 cannot parse into media file

[Attachment 78709 - Click to enlarge] is that mean my keys are invalid or i'm doing something wrong and stupid??

Try this first:
https://www.bento4.com/documentation/mp4info/

mp4info --verbose master-03028928be-1702995022883.en.m4a

and check:
default_KID = [00 00 XX XX XX XX XX XX XX XX XX XX XX XX XX XX]
that matches your KID:KEY

If the KID is right, try this with MP4decrypt:
https://www.bento4.com/documentation/mp4decrypt/

mp4decrypt --show-progress --key KID:KEY master-03028928be-1702995022883.en.m4a master-03028928be-1702995022883-DECRYPTED.en.m4a

More comprehensive guide on using Bento4 tools can be found here.

Try this:

shaka-packager input="WhatIf01.mp4",stream=audio,output="D:\WhatIf01.mp4" --enable_raw_key_decryption --keys label=0:key_id=b3af32f237be4b24d053256eb57f4294:key=3617bd30da9cd5fa39328235fb49155a,label=1:key_id=aa46933d36476da7c869df1b39429898:key=a7834a02f23b750f679a8b708214047b,label=2:key_id=e16c8e7126666089b531168f98cc4406:key=425ee14a0e3a5c30e040341e985389ee

Error is pretty clear to me: it's telling you that the KID of the audio stream you're trying to decrypt is 711121a59... and there's no matching KID:KEY pair for this KID. In other words, those are not the right keys for this stream.
