PGP Encryption
PGP (Pretty Good Privacy) is a data encryption and decryption program that provides cryptographic privacy and authentication for data communication. It uses a combination of symmetric-key cryptography and public-key cryptography to secure emails, files, and other digital communications. PGP is widely used for encrypting, decrypting, and digitally signing messages to ensure confidentiality and integrity.
Developers should learn PGP encryption when building secure communication systems, handling sensitive data like financial or personal information, or implementing email security protocols. It's essential for applications requiring end-to-end encryption, such as secure messaging apps, file transfer services, or compliance with data protection regulations like GDPR. PGP is particularly valuable in scenarios where verifying sender authenticity and preventing unauthorized access are critical.
