Re: [Javamail-crypto-devel] How do I create a pkr file?

[allen p. <al...@su...>]

Hi.

The javamail-crypto library is, at least for now, just a high-level API for 
handling encryption and signing of emails.  While it does have some 
key-management features, it is not meant to be a general-purpose encryption 
API.

That having been said, in the case of PGP, I use gnupg to manage my PGP 
keys.  You can use the gnupg pubring.gpg as the public keystore for 
javamail-crypto.

If you have a public keyring created, and someone sends you an email 
containing their PGP public key, you can use javamail-crypto to import said 
key into your public keystore.  It goes something like

  EncryptionUtils utils = EncryptionManager.getEncryptionUtils(message);
  Key[] extractedKeys = utils.extractKeys(message);
  for (int i = 0; i < extractedKeys.length; i++) {
    net.suberic.crypto.EncryptionKey eKey = 
(net.suberic.crypto.EncryptionKey) extractedKeys[i];
    publicKeyStore.setPublicKeyEntry(eKey.getDisplayAlias(), eKey);
  }

I don't have a way to load the keys just from straight text files.  You can 
either use external tools, or you could just use the Cryptix or 
BouncyCastle APIs directly for that.

I get the feeling that that would be a good feature to add into the API.
