Public Key encryption

[Rüdiger Sonderfeld]

hi again,
now my gcry_pk_genkey() wrapper works. But when I use my function I get the 
output

[open]
  [data="key-data"]
and so on

How can I stop this?

But what is now the public key and what is teh private key?
Which functions do I need to sign/check or encrypt/decrypt with this key?
