Sorry I have to say this but you have got everything exactly
backwards. :-)
I can't decrypt this message. PGP beeps loudly at me and says:
>File is encrypted. Secret key is required to read it.
>This message can only be read by:

Your _public_ key is used to encrypt messages to you and then
you decrypt it with your _secret_ key.
The public key can also be used by me to verify your PGP
signature on a message.
So, if you want to send me an encrypted message:
Encrypt it with my public key.
Sign it with your secret key.
To read it I must:
Verify your signature with your public key.
Decrypt it with my secret key.
I will sign this message and send my public key in a separate
message to the list so you can verify my signature. If you want,
you can also encrypt and send a message directly to me using my
public key. If you sign it with your secret key I can verify
your signature with the key you sent to the list.
I will also encrypt this message with your public key and send
it to the list. You can then decrypt it and compare the two.
There are some issues with mail readers and PGP that I perhaps
can help you with. There can be some trouble with charsets and
transfer encoding and such.
I do hope the key you sent to the list is only for testing
purposes. A 512 bit key is considered by many to be low
security. 1024 or, better, 2048 bits should be used for a
"production" key.
Thank goodness you didn't send your secret key to the list!!!!
Regards,
Lars
