1. Introduction to Folder Encryption: What is it and why is it important?

Folder encryption is a security method used to protect stored confidential information in a computer. It consists of turning files and folders into unreadable data for anyone who does not have the appropriate decryption key. The importance of folder encryption is that it provides an additional layer of protection against unauthorized access and leakage of sensitive data.

There are several reasons why folder encryption is important in the field of computer security. First, it prevents unauthorized people from accessing protected files and folders, even if they manage to gain physical access to the computer. This is especially relevant for those who carry portable devices, such as laptops or USB drives.

Secondly, folder encryption is essential to protect the confidentiality of stored information in the cloud. Many people and companies use cloud storage services to save your important documents and files. Without encryption, this data could be exposed to security breaches and information theft. By encrypting folders before uploading them to the cloud, you ensure that only authorized people can access those files.

2. Types of folder encryption: Symmetric vs Asymmetric

There are two main types of folder encryption: symmetric and asymmetric. Both methods are used to protect sensitive information stored in folders on a device. The choice between these methods will depend on the specific security needs and requirements of each user.

Symmetric encryption involves the use of a unique key to encrypt and decrypt information. This means that the same key is used to both protect and unprotect the encrypted folder. This method is simpler and faster as it uses fewer system resources. However, one disadvantage is that if someone gains access to the key, they could decrypt all the information in the encrypted folder.

On the other hand, asymmetric encryption uses two different keys for encryption and decryption: a public key and a private key. The public key is used to encrypt the information and only the corresponding private key can decrypt it. This method offers greater security because even if someone gains access to the public key, they will not be able to decrypt the information without the private key. However, asymmetric encryption is more complex and requires more computational resources to work. efficiently.
