Is the information in symmetric encryption more secure than the information in PGP?

Q: Suppose two people use symmetric encryption to exchange information, and each time they communicate, the session key is generated, encrypting information using protocols such as SSL that process the session key. In addition, they can exchange information using PGP, a mail encryption software based on the RSA public key encryption system. Which encryption method do you think is more secure in this case, PGP or symmetric encryption? A: It depends on the degree of trust you have in your local environment. Symmetric encryption encrypts all packets between mail servers by using a shared encryption key to ensure that information between systems is not compromised. PGP ensures that personal information is not compromised by encrypting the actual information and making it visible only to the sender and receiver. PGP is more flexible because it can be used when information crosses an insecure network channel, and even if the receiver is in the same system. As a general guide, if you have a trusted messaging environment, but the network between servers is not trustworthy, you can use symmetric encryption. If the information you exchange is sensitive, and even information systems administrators cannot access that information (such as legal or executive information calls), I recommend that you encrypt it using PGP.
