Why PGP offers a strong and secure method of encrypting emails

Understanding PGP BlackBerry encryption is key to determining whether getting a pgp encrypted BlackBerry device makes sense. Basically, PGP (Pretty Good Privacy) for BlackBerry devices uses modified public key system for encrypting email messages. BlackBerry users have private encryption keys that are only known to them and other public encryptions keys, which other users need to know so that they can communicate promptly. The private and public keys work in tandem in various ways. From the sender's perspective, the sender will compose an email and send it. The message at this point is compressed. After compressing, PGP encryption creates one-time, random session keys that are used for encrypting the compressed message on the BlackBerry device used by the sender. It is this session key that will be needed for decrypting the email message.

Since the recipient has a public key, it is this key that will be used to encrypt the session key. The key is only tied to recipient's specific blackberry pgp device. Decryption of the email message will be done by using the private key, which is held by the email recipient on their device. The session key and email message are encrypted and sent to the recipient. Should the message be intercepted, the intruder will not be able to view the message since session key and email are already encrypted and the private key held by the recipient can be used for decryption. From the recipient's perspective, the recipient basically receives an email. At this point PGP encryption will automatically decrypt the session key using recipient's private key.

It is worth noting that the recipient will be the only one who will know the private key since it is private to them. The recipient's private key is usually tied to their phantom blackberry device. This means that no other device or person will be able to fully decrypt the email or session key. In this case, PGP will use the session key in order to decrypt the already compressed message. Once this is done, PGP will decompress the email and the recipient will be able to read the message. From the information above, it is clear to see why PGP for BlackBerry can be used to offer, strong encryption as well as safe and secure email communication.

As with other methods of encrypting information, the encryption method must have a strong algorithm. One reason for this is that an encryption algorithm can only be as strong as computing power that changes with the changing technology. Computational power and technology are increasing every day. As such, the algorithms for strength of PGP keys must also be increased in order to match the computational power. Therefore, it is suffice to say that PGP encryption still remains a strong and secure method of encrypting email messages.
