PGP NetShare uses PGP Keys for encryption, which are in turn encrypted to the session keys. When the PGP Key is unlocked, this in turn will unlock the session key and allow access to the NetShare encrypted data.
If encrypting to many PGP Keys, special considerations should be taken.
If many users do need access, we recommend using the Group Key functionality, which can significantly reduce the amount of needed PGP Keys since the folders would only be encrypted to the Group Keys. In addition to this, it also reduces the administrative cost associated with making the share available to new users, as well as removing access for existing users.

The information needed to access a NetShare folder, is called the metadata. When a file is encrypted with PGP NetShare, the metadata, or a blob is added to the front o the file. The size of this blob will vary depending on how many keys are added to the NetShare protected file/folder and how large the PGP keys are.
