Pomola (http://www.pomola.com) has released AutoCrypt for batch processing encryption of documents. It lets you save in a document all the settings used to create encrypted archives.
Using AutoCrypt, a single click is enough to encrypt hundred of files from a source to another places. Using the blowfish mechanism, all the encrypted files will be totally unreadable by anyone except who knows the correct password, according to the folks at Pomola.
The obtained encrypted files can be transmitted or stored in unsafe place without any security problem. All the setting used to encrypt the original files, are saved inside an AutoCrypt document.
