In symmetric key encryption there is one key that is shared with the person you want to share with your data. The largest disadvantage is that you have to make sure that the key remain secret.
Math algorithms are complex and can easily be broken
Symmetric cryptography only requires one key for both encryption and decryption and therefore in some cases are a issue.
Symmetric
AES
The primary disadvantage of symmetric cryptography is that it requires both parties to share the same secret key for encryption and decryption, which poses a significant key distribution challenge. If the key is intercepted during transmission or if it is compromised, the security of the entire communication can be breached. Additionally, managing and securely storing keys becomes increasingly complex as the number of users grows, leading to potential vulnerabilities.
There are 2 types of cryptography such as: 1- Symmetric-key or Secret key Cryptography 2- Asymmetric-key or Public key Cryptography

Lmfao - do Richard kays coursework by yourself instead of asking others to answer it for you.
following steps are involved in symmetric cryptography 1- sender creates a ciphertext message by encrypting the plain text message with a symmetric encryption algorithm and a shared key. 2- the sender sends the ciphertext message to the recipient. 3- the recipient decrypts the ciphertext message into plain text with a shared key.
Symmetric cryptography is impractival when a large group is involved.
Symmetric-key algorithms are a class of algorithms for cryptography that use trivially related, often identical, cryptographic keys for both decryption and encryption.
