IF wechall sent email to me by using my public GPG_Key?  Gehe zur Training: GPG Challenge

or using wechall itself private GPG_Key?
Please give me some hint,
I thought it almost whole day T_T
thanks very much!

Almost took me a day to decipher your question as well. I believe you are asking: "Does WeChall send e-mails to me using my public GPG key or using WeChall's own private GPG key?"

If you are, you don't seem to understand how asymmetric cryptography works. Perhaps read up a bit on that.

As for the challenge itself: read the challenge description. It tells you exactly what to do.

I seem to be stuck on this one at the moment as well. Perhaps one of the pros can give me a hint about what in my key export block is incompatible with what the challenge is expecting as input.

-----BEGIN PGP PUBLIC KEY BLOCK----- Version: GnuPG v1   <#--- rest of block is redacted for posting, contains signed pubkey ---#>

Any tips or suggestions are appreciated.

There isn't much I can see from what you posted. Perhaps you forgot to include the final part?

It being a public key, there is really no reason why you can't post it completely. If you prefer, you can also PM me.

Thanks for the reply dloser, my GPG pub key was accepted on a subsequent attempt, and I was able to complete this challenge.
Persistence pays off
