Question 1

What is PGP Command Line?

Accepted Answer

PGP Command Line is a utility for encrypting and decrypting files and datasets. It uses the Pretty Good Privacy (PGP) standard for secure data protection. The tool provides command-line options for encryption, decryption, key management, and digital signatures.

Question 2

Who developed PGP Command Line?

Accepted Answer

PGP Command Line was initially developed by PGP Corporation. It was later acquired by Symantec, and subsequently by Broadcom. The tool's development and support have evolved through these corporate changes.

Question 3

What are the common use cases for PGP Command Line?

Accepted Answer

PGP Command Line is primarily used for securing sensitive data at rest. Common use cases include protecting confidential files, encrypting data before storage or transmission, and ensuring data integrity through digital signatures.

Question 4

What file types and datasets does PGP Command Line support?

Accepted Answer

The tool supports various file types and datasets. It can encrypt and decrypt individual files, archives, and datasets. The specific file type support depends on the underlying operating system and available utilities.

Question 5

What are the most common commands and their syntax?

Accepted Answer

Common commands include encrypting files (`pgp -e`), decrypting files (`pgp -d`), signing files (`pgp -s`), verifying signatures (`pgp -v`), and managing keys (`pgp --list-keys`). The syntax involves specifying the command, input file, output file, and any required key identifiers.

Question 6

What configuration files or interfaces are used?

Accepted Answer

PGP Command Line uses configuration files to store settings such as key locations and default parameters. These files are typically located in the user's home directory or a system-wide configuration directory. The tool also interacts with the operating system's file system for input and output operations.

Question 7

What types of APIs does PGP Command Line expose?

Accepted Answer

PGP Command Line does not expose APIs for direct integration. It is primarily a command-line utility. Integration with other applications is achieved through scripting or by calling the command-line tool from within scripts or programs.

Question 8

What are the main system components?

Accepted Answer

The main components include the command-line interface, the encryption engine, the key management system, and the file I/O module. These components interact to perform encryption, decryption, and key operations. The encryption engine handles the cryptographic operations, while the key management system manages the keys.

Question 9

What is the business value of using PGP Command Line?

Accepted Answer

PGP Command Line provides value by securing sensitive data, ensuring data confidentiality, and enabling secure data exchange. It helps organizations comply with data protection regulations and protect against data breaches. The tool's command-line interface allows for automation and integration into existing workflows.

Question 10

How does PGP Command Line enable secure data exchange?

Accepted Answer

The tool enables secure data exchange by allowing users to encrypt files before sharing them. This ensures that only authorized recipients with the correct decryption keys can access the data. Digital signatures verify the data's integrity and authenticity.

Question 11

How does PGP Command Line help protect sensitive data?

Accepted Answer

By using PGP Command Line, organizations can protect sensitive data stored on various platforms. This helps prevent unauthorized access and data leaks. The tool's encryption capabilities ensure that even if data is compromised, it remains unreadable without the correct keys.

Question 12

How can PGP Command Line be integrated into existing workflows?

Accepted Answer

The command-line interface allows for easy integration into existing scripts and automated processes. This enables organizations to incorporate encryption and decryption into their workflows without manual intervention. This automation saves time and reduces the risk of human error.

Question 13

What encryption algorithms are supported?

Accepted Answer

PGP Command Line supports encryption using the PGP standard, which includes algorithms like AES, CAST5, and Triple DES. It uses public-key cryptography for key exchange and symmetric-key cryptography for bulk encryption. The specific algorithms used can be configured.

Question 14

What authentication methods are supported?

Accepted Answer

Authentication is primarily handled through the use of digital signatures. Users can sign files with their private keys, and recipients can verify the signatures using the corresponding public keys. This ensures the authenticity and integrity of the data.

Question 15

What access control model is used?

Accepted Answer

PGP Command Line supports access control through the use of encryption keys. Only users with the correct decryption keys can access the encrypted data. Key management practices, such as key revocation and access control lists, are crucial for maintaining security.

Question 16

What audit/logging capabilities exist?

Accepted Answer

PGP Command Line provides logging capabilities to record encryption and decryption events. These logs can be used for auditing and security monitoring. The level of detail in the logs can be configured to meet specific security requirements.

Question 17

What administrative interfaces are available?

Accepted Answer

Administrative interfaces are primarily command-line based. Users interact with the tool through commands entered in a terminal or command prompt. There is no graphical user interface (GUI) or web console available for administration.

Question 18

How is user management handled?

Accepted Answer

User management is handled through key management. Users create and manage their own encryption keys. The tool does not have built-in user management features beyond key creation, import, export, and revocation.

Question 19

What are the main configuration parameters?

Accepted Answer

The main configuration parameters include key locations, default encryption algorithms, and log file locations. These parameters are typically set through command-line options or configuration files. Proper configuration is essential for secure operation.

Question 20

What monitoring/logging capabilities exist?

Accepted Answer

Monitoring and logging capabilities are provided through log files. These logs record encryption and decryption events, key management operations, and any errors. Administrators can monitor these logs to identify potential security issues or operational problems.
