Abstract
A method for recovering encrypted content from structured files is provided. During an encryption process, a known pattern of metadata may be inserted into each of a set of headers of the encrypted content and each of a set of footers of the encrypted content. The processing logic may insert the encrypted content into a structured file and subsequently (e.g., during an attempt to access the content) detect that a structure of the structured file has been damaged. The encrypted content may be identified by identifying one or more of the set of headers and one or more of the set of footers of the encrypted content. In this way, the method allows for partial recovery of encrypted content and prevents total loss of the content in situations where the structure of the file including the encrypted content is damaged.
