Comparison of different encryption techniques.

Technique	Type	Key Length (/bits)	Strengths	Weaknesses
AES	Symmetric	128/192/256	High security, efficient in hardware/software	Requires secure key management
RSA	Asymmetric	1024~4096	High security for key exchange, widely supported	Slower for large data sets
ECC	Asymmetric	160~512	Similar security to RSA with shorter key lengths	Complex implementation, parameter sensitivity
TLS	Protocol	Varies based on the key type	End-to-end security, widely adopted	Requires proper configuration
ChaCha20-Poly1305	Symmetric with MAC	256	High performance, secure	Newer, less tested compared to AES
