Symmetric algorithms are very efficient and work with a single key for both encryption and decryption calculations.

对称算法非常有效，并且可以与用于加密和解密计算的单一密钥一起使用。

Public-key algorithms, on the other hand, are asymmetrical, using different keys, a public key, and a secret key, for encryption and decryption.

公开钥匙算法则是不对称的，采用不同的密钥，一个公开的钥匙和一个秘密的钥匙，用于加密和解密。
