Research In Motion today announced that BlackBerry email will soon gain the ability to be secured by PGP. While there will be an extra cost associated with the service, PGP provides sender-to-recipient email security in the form of high-grade public key encryption.
Users simply authenticate themselves with their private key passphrase before decrypting or signing email on their BlackBerry device. Outgoing messages are automatically protected according to the centralized policy specified by the PGP Universal administrator. PGP Universal utilizes patented PGP Additional Decryption Key (ADK) capabilities, automated key management and recovery, and automated enrollment and centralized policy management.
The PGP Support Package for BlackBerry is expected to be available later this year.
In case you were curious, PGP stands for Pretty Good Privacy. There's a lot of interesting reading as to how exactly the technology works (I find encryption really interesting) but in short it's really tough to crack.
