File Level Encryption
File Level Encryption is a security technique that encrypts individual files or data objects, protecting them with cryptographic keys to ensure confidentiality and integrity. It operates at the file system or application layer, allowing granular control over access to specific files rather than entire storage volumes. This method is commonly used to secure sensitive data such as documents, databases, or media files in storage or during transmission.
Developers should learn and use File Level Encryption when building applications that handle sensitive user data, such as financial records, personal information, or proprietary content, to comply with regulations like GDPR or HIPAA. It is particularly useful in cloud storage, backup systems, and file-sharing services where fine-grained access control is needed, as it enables encryption of specific files without affecting the entire system's performance or accessibility.
