For those of you, who are using the excellent GPGMail mail bundle, here are some hints that might be interesting. I use GPG on a daily basis and thus I have my own preferences (which hash algorithm to use and which cipher, etc.).
With the gpg bundle in Mail.app, your hash will always default to SHA1, something I disliked. Therefore I took the time and mailed the author, he was very helpful and told me that you can fine tune some of the setting for this application by altering the values in /Library -> Mail -> Bundles -> GPGMail.mailbundle -> Contents -> Resources -> GPGMailBundle.defaults. The values you may alter are:

The values you may alter are:
- GPGAuthenticatesMessagesAutomatically = NO;
- GPGBadAuthenticationAlertOnly = NO;
- GPGAlertForUnsignedEncryptedMessages = YES;
- GPGDecryptsMessagesAutomatically = NO;
- GPGAlwaysSignMessage = NO;
- GPGDefaultIdentity = "";
- GPGRemembersPassphrasesDuringSession = NO;
- GPGHashAlgorithm = "SHA1";
- GPGTraceEnabled = NO;
- GPGLogStderrEnabled = NO;
- GPGPassphraseFlushTimeout = "60.0";
- GPGEncryptsToSelf = YES;
- GPGOpenPGPStyleOnly = NO;
- GPGUsesEncapsulatedSignature = YES;
% defaults write com.apple.mail GPGHashAlgorithm RIPEMD160This is an example of how to change your Hash from SHA1 to RIPEMD160. I hope this helps some of you, please do not forget to set your gpg options either.
