What is one of the primary weaknesses of symmetric cryptography?

• Hard disk storage
• RAM memory requirement
• CPU processing speed
• Key Management 

EXPLANATION

Symmetric cryptography is usually fast and easy to implement. This is because encryption and decryption with a private key requires less complex computation than other types of cryptography. The significant disadvantage of symmetric encryption relate to the difficulties of managing the private key.
