- How would the Crypto Keys be managed? PGP protected emails would require decryption keys that only the sender and recipient would have to read the content transmitted between the two, and ideally Google won't have access to the messages.
- What about the features of Gmail that rely on Email Content? This means that the adoption of PGP encryption could be problematic for Google as it won’t allow them to scan your emails to serve its spam filtering feature, content-based advertisements and even the search option.
Stronger end-to-end encryption will certainly be appreciated by Gmail users, but meanwhile you should know that major Desktop Email clients such as Microsoft Outlook and Mozilla Thunderbird with the Enigmail plugin can be configured manually to work smoothly with PGP encryption software, making it a simple matter of clicking a button to sign, verify, encrypt and decrypt email messages.
