PGP
PGP (Pretty Good Privacy) is a data encryption and decryption program that provides cryptographic privacy and authentication for data communication. It is commonly used for securing emails, files, and digital signatures by using a combination of symmetric-key cryptography and public-key cryptography. PGP ensures confidentiality, integrity, and authentication in digital communications.
Developers should learn and use PGP when they need to secure sensitive data, such as encrypting emails, signing software releases, or protecting files during transmission. It is particularly valuable in scenarios requiring end-to-end encryption, compliance with data protection regulations, or verifying the authenticity of digital content. PGP is essential for roles involving cybersecurity, secure software distribution, or handling confidential information.
