Definition
Open Pretty Good Privacy (OpenPGP) is a protocol that facilitates data encryption and decryption. It is based on the Pretty Good Privacy (PGP) protocol and combines symmetric-key and public-key encryption to protect data.
The protocol allows you to generate key pairs, which consist of a public key for encryption, a private key for decryption, and a digital signature.
OpenPGP Examples
- File encryption: OpenPGP can encrypt files, making them almost impossible to access without a proper decryption key.
- Email encryption: Email service providers use OpenPGP to encrypt emails, ensuring only the intended recipient can read them.
OpenPGP Pros
- Security: OpenPGP uses powerful cryptographic algorithms for encryption, decryption, and signature, ensuring a high-security level.
- Non-proprietary: Since it’s an open standard, OpenPGP is widespread and be implemented in any software that supports it.
OpenPGP Cons
- Time-consuming: The heavy computational workload can slow the encryption and decryption processes.
- Complexity: The complex key management system can be challenging for beginners.
