Quote from: TurboSti on July 17, 2012, 12:46 amI'm new here obviously so if I missed something please point me in the right direction but I'm using gpg4usb but when I try to decrypt someones key I get an error message that says "no data" I have my keys selected and I've even seen on the gpg website with their picture tutorials and I'm doing everything right except I get this message and can't get any further.You don't decrypt someone's public key, you import it into your public keyring and encrypt messages or files to the public keys you have (including your own if you want to be able to decrypt it later).
