Abstract
A decryption scheme for recover of a decrypted object without a cryptographic key is described. First, logical operation(s) are conducted on data associated with a first data string expected at a first location within an object having the predetermined format and data within the encrypted object at the first location to recover data associated with a portion of a cryptographic key from the encrypted object. Thereafter, logical operation(s) are conducted on that data and a first portion of the encrypted object at a second location to produce a result. Responsive to the result including data associated with the plaintext version of the second data string, logical operation(s) are conducted on a second portion of the encrypted object and the data associated with the plaintext version of the second data string to recover data associated with the cryptographic key. Thereafter, the encrypted object may be decrypted using the cryptographic key.
