I'm developing a web app which emails encrypted data (from a web form) to a client who uses Macs/OSX exclusively in their office.
I'd like to know: Is there are any reliable solutions for PGP / GnuPG decryption on Mac OSX mail?
I've come across Symantec's solution, but haven't read a great deal of positive feedback on it.
What about GPGTools? Has anyone had experience with it? Does it work seamlessly with Mac Mail? I can't remember where I read it and can't find it now, but can GPGTools decrypted email be index/searched in Mail? How susceptible is it to being disabled on a Mac Mail or OSX update?
