Symmetric Cryptography Vs Asymmetric Cryptography

Symmetric Cryptography	Asymmetric Cryptography
In symmetric cryptography, same key is used for encryption and decryption.	In asymmetric cryptography, different keys are used for encryption and decryption.
It is also known as private key cryptography.	It is also known as public key cryptography.
It is faster than asymmetric cryptography.	It is slower than symmetric cryptography.
It is less secure.	It is more secure.
It is less complex.	It is more complex.
Secret channel is required to send the secret key.	No secret channel is required for the exchange of public key.
The most commonly used symmetric algorithms include DES, AES and RC4.	The most commonly used asymmetric algorithm is RSA.
