What is the advantage of PGP zip over winzip AES
hope this artical will help you.
I tried Google for finding a comparison. This might be helpful:
What immediately comes to mind for me is that PGP Zip offers public key encryption and its advantages in exchanging encrypted files with others. I consider public key encryption potentially more secure, since it's decryption requires possession of both the required private key and it's passphrase; while conventional encryption requires only the passphrase for decryption.

Thanks for the info Tom Mc,
In addition to that I found this:
For AES and PGP comparison,
The above is really a discussion of symmetric encryption (first part of above) and asymmetric encryption (the latter part). While AES may be considered the best symmetric algorithm for symmetric encryption, there are other good ones that can be used, so that info is not complete. The asymmetric discussion above is also not fully correct. With asymmetric encryption used in PGP, the data is actually symmetrically encrypted (PGP defaults to using AES). It is then the randomly generated AES symmetric key used for the data encryption that is encrypted to a public key of the recipient. The recipient uses his/her private key to decrypt the AES key, and the AES key is then used to decrypt the data. So, in either case, symmetric encryption is used (because it is so much faster than asymmetric encryption. And the public key encryption is used as a secure way of transmitting the symmetric (in this case, AES) key.
I probably should have also clarified that PGP Zip can be used for either just symmetric encryption (encryption to just a passphrase; often called conventional encryption) or public key encryption.

One big advantage is that PGP is an IETF standard (RFC 4880). The use of AES in WinZIP is completely proprietary.
Do you have further concern with this?
