The Security of PGP Programs

PGP stands for pretty good privacy, and is a kind of encryption and decryption program for computers, which originates from cryptography. The concept behind this technology is taken from Julius Caesar, who used to send encrypted messages to his Generals because he did not trust the messengers. Only the ones who knew the formula to decrypt it could read the message and no one else could.

In current times, this program is available to anyone who wants to use it and it is not that difficult to use either. The user has a private key of their own, which is password protected, and a public key which the other user has, to send the message. PGP is there in phones, like PGP blackberry, and it is there in computer devices as well. Since it is developed from the concept of cryptography, here is some information on it.

·         Cryptography is the science of using mathematics to encrypt and decrypt data. It allows you to accumulate sensitive information or send it across insecure networks like the internet, all the while not letting unwanted people catch hold of such information.

·         PGP works on a cryptographic algorithm which is a mathematical function used in the process of encryption and decryption. These algorithms work hand in hand with a key, like a word or a number, to encrypt the plaintext. And what is interesting is that the same plaintext would come out differently when using different public keys.

So, whether it’s PGP blackberry or any other device, it is a good way of securing your information.

Various Applications of Encryption

As the cybercrime is rapidly increasing on the internet, the demand of encryption is also enhanced with it. Encryption is a trouble-free technique. In this, you have to convert your message or data into another format which is unreadable. The original message is known as “plain text” and converted or unreadable data is known as “Cipher text”. Encryption has three main applications that are:-

1. File or Folder encryption:-

In this, the individual file or directory is encrypted by using some method or algorithms. The decryption method or keys are also stored in the memory to decrypt the data. The PGP file encryption method doesn't decrypt the meta data of the file.

2. Database Encryption:-

To transform the data of the database so that untrusted person can't read it is known as database encryption. This technique also protects data from hackers. You can encrypt only a column or number of columns in Database encryption method.

3. Web encryption:-

While using the internet, sometimes “HTTPS” appears in some websites URL which means this is HTTP secured. It is the other method of encryption used on the internet to secured the data. Highly secured schemes are used to secure the internet data.

Various encryption schemes and methods are used to protect the crucial data from the unauthorized person.

Various features of the Pretty Good Privacy

For encryption and decryption of data, Pretty good Privacy or PGP program is very popularly used these days. To save the time, PGP encryption is an ideal option. PGP encrypt the data by applying a shorter key and a faster encryption algorithm on it. It uses the combination of data compression, hashing, public key cryptography and symmetric key cryptography.

It helps in sending encrypted messages confidentiality. For this confidentiality, the message is encrypted using a symmetric encryption algorithm. Its session key and encrypted message send to the receiver. Many companies provide Blackberry PGP, Apple PGP, Samsung PGP and a lot of more topmost brands with PGP security. PGP also supports the Digital signatures. As, Digital signatures is a mathematical technique used by the experts to encrypt the data. It supports the authenticity and integrity of a message, files, software, digital document and other important data.

Apart from the digital signatures, PGP also supports the concept of digital certificates. These certificates are issued by a valid certificate authority. It is used to allocate the pair of keys to a valid person. To protect data in long-term data storage, PGP encryption can be used and it also helps in transmit the secured data safely over a network. 

PGP program is crucial for the banking, business, trade, institutions and other relevant areas.

Various Benefits of Encrypting Data

As we know that all the essential information, data and files are stored on the electronic devices such as Computer, mobiles, smartphones, tablets, ipads and a lot of more. We don't want that any person read or access that crucial information without our permission. So, we apply the encryption technique on the data. Encryption converts the data into a non-readable data that is difficult to understand. It keeps the data secure and safe from everyone.

Moreover, Encrypted data can easily transmit through emails or messages as you very well know that no unauthorized person can read your important data. For this encryption, various schemes and software are used that protect your data. The receiver receives the encrypted data and convert it into the original information through decryption technique.

Encryption keeps the integrity of data which means no modification or manipulation is done while transferring the encrypted data. You can freely send your encrypted data without the problem of data theft. For this, many pgp encryption software is used that secure the information from hackers and unauthorized persons.

If somehow, you lose your phone or laptop that contain some important data like bank account number, personal images, office information or much more then, you no need to worry about the loss of that information as it is encrypted by various advanced schemes. No one can read or understand you personal data.

Therefore, encryption of data is very helpful in banking transactions, Corporate IT world, Business and other similar areas.
