for it - and found helpful instructions on MacGPG-site.
- Download the files from Sourceforge. You'll surely need "GnuPG for OSX" and "GPG KeyChain Access" (makes life much easier).
- Point your browser to the cool docu (by Zeitform).
- In case you need to pgp-encrypt EMail (I'm sure you need to!), get GPGMail (from SENTE), also free.
Installation is very straightforward.
Then you
- (must) generate your own key (unless you already have one and it's still valid!),
- (should propably) upload your public key to a keyserver (the default keyserver of GPG works fine),
- (have to) find the keys of your communication partners, either on the public keyservers or from them directly,
- (should) publish your key's fingerprint, so others can verify a downloaded key... (put it on your website, find mine here). In case your're too lazy to klick: 9E64 477B 0BCF A2C6 C868 68B3 CF32 9C31 4E1A 26BA
And you're done: From now on, your mails or files can look like (snippet from the pgp'd version of this post:)
