PGP(Pretty Good Privacy)

PGP(Pretty Good Privacy) is a based on RSA public key encryption system E-mail encryption software. Can use it to prevent the confidentiality of the mail, it still can disburse reading of the mail add digital signatures so that the recipient can confirm email sender, and can be assured that the mail is not being tampered with. It can provide a safe way to communicate, and prior did not need any confidential channel used to deliver key. It USES a kind of RSA and traditional encrypted miscellaneous economical method for digital signatures mail abstract algorithm, encryption, and a former compressing the ergonomic. Good It has powerful functions, have very fast. And it's source code is free.

introduction

PGP is a private key based on RSA public key and of the encryption algorithm and AES encryption software such as the series.

Common version is PGP does (PGP Professional thing, it contains Desktop version) with identity confirmation email encryption private key, material public key encryption, hard drives and overall password protection and mobile disk, the network sharing data encryption, PGP self-extracting document creation, data security erasing, and many other functions.

The final version: build13] [10.02 PGP (PGP SDK 4.0.0).

Because of the company's acquisitions affect symantec, PGP 10.0.2 later, will no longer from the independent alone emit PGP version installation kits form, will be in the form of plug-ins, and other safety integrated in symantec security products such as NORTON.

Your company may have many ways to protect information. For example, may use locked doors in isolation, building a closed space, then only allow authorized person discrepancy company also can ask staff must use personal account number and password to login network, but erect firewalls server to monitor all internal and external information transmission between.

These mechanisms are to strengthen information is confidential.

PGP can provide independent computer information on the protection function, make this more complete secrecy systems. It provides these functions: data encryption, including E-mail, any stored files, and instant messaging (for example ICQ etc.).

Data encryption functionality that allows users to protect their message ─ like E-mail and they stored in the computer information. Documents and information through the user's key, through the complex algorithm operations, only after they receive coding talent can bring these documents and information decoding.

function

Now you should have probably for PGP already know. Let us see what actually has PGP functions: the use of encryption and verified by PGP way, offers a variety of functions and tools to help you ensure your email, files, disk, and network communication safety. You can use PGP do these things:

1, in any software to encrypt and decrypt / / signatures verified. Through the PGP options and E-mail plug-ins, you can use any software in among the function of PGP.

2, create and the management of the key. Use PGPkeys to create, view, and maintain your own PGP key to; And the public of anyone to join your public key library.

3, create the decryption compression document (get decrypting archives, SDA). You can set up an automatic declassification executable files. Anyone who does not need pre-installed PGP, as long as that the file encryption password, you can take this file decryption. This function especially in need to send the documents without the person particularly handy installation PGP. And, this function can also internally inlay file compression, compression ratio and ZIP similar than RAR slightly low (, at certain times slightly tall, such as contains a lot of text). Overall, this function is fairly good.

4, create PGPdisk encrypted files. This function can create a PGD documents. The file using PGP disk.support function loaded, will take the form of a new partition, here you can partition is put inside any of the files needed to remain confidential. Its use Shared private key and password both the ways to save encrypted data, secrecy, but note yielded, must be in reshipment system before remember backup "my documents" of the "PGP" folder all files for reshipment hind restore your private key. Remember remember, otherwise will never might again in the system open once created any encrypted files!

5, permanent crushing destruction of documents and folders, and release of disk space. You can use PGP crushing tools to permanently delete those sensitive files and folders, and can't be trapped any data segment on disk. You can also use PGP free space smash again) has been deleted files clear real occupants disk space. The two tools are to ensure that you have to delete the data will never may be ax-grinders recovery.

6, 9. X feature: overall encryption, also say the complete disk encryption. This function can send your entire hard disk data encryption, even including all operating system itself. Provide extremely high safety, no password people can't possibly using your system or check deposited disk files, folders in such data. Even hard disk was removed to another computer, this function will still loyal to protect your data, encrypted data to maintain the original structure, files and folders position will not change.

7 and 9. X enhancement: instant messaging tools encryption. This function can will support instant messaging tools (IM, also called the instant communication tools, chat tools) are sending information via PGP processing, only completely with the corresponding private-key other and password can unlock news content. Anyone have any meaning to also intercepts, just a pile of garbage characters.

8, 9. X feature: PGP zip, PGP compressed package. This function can create a similar other compression software package compressed packages, but different is its own impregnable safety.

9, 9. X enhancement: network share. Can use PGP taking control of your Shared folder itself and one of the documents, safety far above the operating system itself provides account verification function. And can be convenient management allows the authorized user of the operation can be. Great convenience in internal networks need to often share files by the enterprise users, from worm virus and hacker attacks.

10, 10. X feature: create Portable encryption medium (USB/CD/DVD) products: PGP make. Once independent this product has been contained in it, but when using need another purchase license.
