Encryption ensures data confidentiality. Mastering symmetric ciphers (AES), asymmetric key exchanges (RSA/ECC), and key generation secures application data from intrusion.
Topic Overview
Cryptography is divided into two primary disciplines: symmetric encryption (using a shared secret key for fast coding) and asymmetric encryption (using key pairs).
Deploying these configurations requires managing keys, choosing padding standards, and evaluating key length security profiles.
Symmetric Encryption and AES
The Advanced Encryption Standard (AES) is a symmetric block cipher standardizing on 128-bit blocks with key options of 128, 192, or 256 bits.
AES is fast, making it ideal for disk encryption, database fields, and bulk file security. It relies on secret keys that must be shared securely.
Asymmetric Key Pairs and RSA
Asymmetric cryptography uses a public key to encrypt data and a private key to decrypt it. RSA has been the standard asymmetric cipher, relying on prime factorization math.
Because RSA key generation requires massive prime numbers, generating RSA keys in-browser requires secure random entropy sources to avoid predictable key patterns.

Frequently Asked Questions
- What is a public/private key pair?
- A public key can be shared with anyone to encrypt messages, while the corresponding private key must be kept secret to decrypt those messages.
- Why is ECC preferred over RSA in modern networks?
- Elliptic Curve Cryptography (ECC) provides the same security level as RSA but with significantly smaller key lengths, resulting in faster handshakes and less bandwidth usage.
