What is Encryption?
Encryption transforms plain data into a coded format that can only be read with a decryption key. It protects the confidentiality of sensitive information and is a cornerstone of secure communication and data storage.
Common Algorithms
- AES (Advanced Encryption Standard)
- RSA (for public key encryption)
- ECC (Elliptic Curve Cryptography)
Best Practices
- Use strong, modern encryption standards
- Rotate keys regularly
- Never store plaintext sensitive data
- Use HTTPS for all web traffic
