What is PGP?
(Pretty Good Privacy) is one of the most common encryption techniques used today. It is used to secure the most confidential information with a higher standard of data security protection for banks , financial institutions, healthcare organisations, and other heavily regulated industries. PGP has been developed and upgraded through the years , making it the traditional alternative for today’s file encryption and a suitable solution for modern cyber security needs.It is considered one of the safest cryptographic signing, encryption, and decryption technologies for sensitive data.
How Does PGP Encryption Work?
PGP encryption offers the basic protection that is lacking from electronic contact by turning plain, legible text into a complicated language of unreadable characters. The communication outlet (e-mail, file, etc.) travels in this ciphered form to the recipient’s destination. The recipient instead uses PGP to decode the document into a readable form again. PGP encryption is done through applications software.
consumer in this scheme has a publicly available encryption key that can be given to the recipient, as well as a private key that is accessible exclusively to another consumer and will be kept confidential. The public key encrypts the message or file, while it decrypts the private key.
More precisely, for transmitting data, the sender would require access to the secret key of the receiver first before they can transfer their data. Once the file is compressed, PGP will use private key cryptography to effectively encrypt the plaintext, turning the message into ciphertext. Afterwards the session key is authenticated using the public key of the sender.If the receiver has obtained the encrypted file, they will use their private key to decrypt it.
Advantages of PGP Encryption
- Sensitive information is always protected. It can’t be copied or accessed over the internet by anyone. It guarantees that the information submitted or obtained in transmission has not been changed and that data have not been manipulated without your awareness.
- Information can be securely shared with others including user groups and entire departments.
- You can rest assured who the email is from and for whom it is. PGP verifies the source of the details to insure that a single entity managed to decrypt the data.
- Hackers can not penetrate your secure emails and messages or get infected with email attacks.
- Others will not be able to recover sensitive messages or files once you delete them.
- PGP security program is incredibly simple to understand to use. With virtually no training, users will be able to learn how to use it immediately.
Disadvantages of PGP Encryption
Compatibility issues:- Both sender and receiver must have PGP versions which are compatible. For instance, if you encrypt an email using one of the encryption techniques using PGP, the receiver has a different version of PGP that can not read the data.
The Administration is difficult:- The various implementations of PGP allow management more difficult.
Complexity:- PGP is a dynamic operation. Many authentication systems use symmetric encryption using one key or asymmetric encryption using two separate keys. PGP uses a hybrid approach that implements double-key symmetric encryption. PGP is more complex than traditional symmetric or asymmetric methods, and less familiar.
No Recovery:- Computer administrators face the loss of their passwords. In these cases an user can recover passwords using a special application. A technician, for instance , requires physical access to a Computer and can be used to receive a password. PGP does not offer such a specials recovery program however; encryption methods are therefore very strong,The forget keys are not recovered resulting in missing communications or information.
