PGP is a tried and tested encryption technique which is proven to be secured. It permits users to employ a better encryption standard on BlackBerry email accounts. We use the standard PGP platform encryption RSA 4096 bits partnered with AES 256.
Pretty Good Privacy or PGP is a popular program used to encrypt and decrypt email over the Internet, as well as authenticate messages with digital signatures and encrypted stored files.Pretty Good Privacy or PGP is a popular program used to encrypt and decrypt email over the Internet, as well as authenticate messages with digital signatures and encrypted stored files.
How PGP works
Pretty Good Privacy uses a variation of the public key system. In this system, each user has an encryption key that is publicly known and a private key that is known only to that user. You encrypt a message you send to someone else using their public key. When they receive it, they decrypt it using their private key. Since encrypting an entire message can be time-consuming, PGP uses a faster encryption algorithm to encrypt the message and then uses the public key to encrypt the shorter key that was used to encrypt the entire message. Both the encrypted message and the short key are sent to the receiver who first uses the receiver’s private key to decrypt the short key and then uses that key to decrypt the message.
PGP comes in two public key versions — Rivest-Shamir-Adleman (RSA) and Diffie-Hellman. The RSA version, for which PGP must pay a license fee to RSA, uses the IDEA algorithm to generate a short key for the entire message and RSA to encrypt the short key. The Diffie-Hellman version uses the CAST algorithm for the short key to encrypt the message and the Diffie-Hellman algorithm to encrypt the short key.
When sending digital signatures, PGP uses an efficient algorithm that generates a hash (a mathematical summary) from the user’s name and other signature information. This hash code is then encrypted with the sender’s private key. The receiver uses the sender’s public key to decrypt the hash code. If it matches the hash code sent as the digital signature for the message, the receiver is sure that the message has arrived securely from the stated sender. PGP’s RSA version uses the MD5 algorithm to generate the hash code. PGP’s Diffie-Hellman version uses the SHA-1 algorithm to generate the hash code.
Who uses BlackBerry PGP services?
This encryption service finds a wide swathe of subscribers, from security conscious individuals to public as well as private companies, including government bodies. BlackBerry devices are ideal for implementing and supporting a PGP framework. It is a common encryption solution for both businesses and individuals.

In PGP encryption, a public key is used for asymmetric cryptography. Two keys are used for this kind of encrypted information, one to encipher information, and the other to decipher it. The public key, unlike the secret key, is exchanged between the sender and the recipient. The RSA algorithm performs these functions.
