Cryptography / 密码学

To implement AES-GCM encryption for data at rest, use a symmetric cryptographic approach with authenticated encryption to ensure both confidentiality and integrity. This Skill provides practical code examples and structured references for AES-GCM integration.

Symmetric cryptography uses a single shared key for encryption and decryption, while asymmetric cryptography uses a public-private key pair. This Skill details concepts and formulas for both, covering algorithms like AES and RSA.

A TLS handshake establishes a secure connection using asymmetric cryptography to exchange session keys, validated against PKI certificates. This Skill provides structural references and practical examples to validate PKI and TLS configurations.

Yes, this cryptography reference is applicable for both software development and educational study. It provides structured coverage of hashing, PKI, and protocols with practical code implementations across theoretical and practical coding tasks.

Use RSA for broad compatibility and ECC for smaller key sizes with equivalent security. This Skill outlines asymmetric cryptography concepts, formulas, and practical code examples for both RSA and ECC algorithms.

Hashing algorithms generate fixed-size digests to verify data integrity. This Skill provides organized coverage of cryptographic hashing concepts and formulas alongside practical implementations for security practice.
