Abstract: Electronic document processing logic coupled to a computer and to a quarantine is operable to identify an encrypted electronic document received at the computer; determine whether the key server stores particular decryption data, or credentials to access decryption data, that can decrypt the encrypted electronic document; in response to determining that the key server does not store particular decryption data that can decrypt the encrypted electronic document: store the electronic document in the quarantine; notify one of the users; receive from the one of the users the particular decryption data; decrypt the electronic document; scan the electronic document to identify specified content in the electronic document; and perform one or more responsive actions based on the specified content. As a result, encrypted content in documents or e-mail can be decrypted, scanned for viruses, malware, or prohibited content, and re-encrypted or delivered.

Abstract: Embodiments are described that leverage commonly used HTML tags to enable the transfer of large quantities of data in a network. Embodiments are described where large amounts of data can be sent to a server by fragmenting data into small portions and encoding each portion as part of a URL contained in, for example, the src attribute of an <img> tag. The path of this URL can refer to a predetermined resource contained on the server that is responsible for retrieving fragments of data from the requested URL. Each fragment of data can be sent together with whatever additional pieces of information are required by the server to correctly reassemble the portions to obtain the original, defragmented data. Methods are described that enable a client to communicate an arbitrarily large amount of data to a server using only the GET method.

Abstract: An apparatus, method, and computer-readable medium capable of extracting a payload file or files from a platform-independent, self-extracting, encrypted document. Embodiments include the creation of platform-independent, self-extracting archives that may be encrypted or unencrypted, execution of a platform-independent self-extracting archive.
