[ don't snoop me ] Ciphire came out with a cool encryption application that will protect your existing email client. Ciphire Mail uses only well-known standard cryptographic algorithms including RSA, AES, Twofish, or SHA for its cryptographic operations. It uses 2048-bit keys for asymmetric algorithms and 256-bit keys for symmetric algorithms. I think this is great but the only gotchya is that not everybody uses this nor has the reason to. Really, how many ppl are out there sniffing your emails? I can see this being useful at airports or any other public transport or WiFi site. But then again the ppl receiving your emails from these public sites of concern would need the app to decrypt your email.
