<p>A method and system is disclosed for encrypting and decrypting data, with decryption contingent upon user-defined conditions being met. The encryption process comprises a method for using pointers to indicate the locations and sizes of encryption components, utilizing randomly determined patterns to be used for a random number of characters of text data being encrypted. For each randomly determined block of text, a randomly determined pattern is selected, which specifies how to combine the encryption components, including the shuffled and encrypted text, and references to that block's seed key, the size and composition of which are randomly determined. Decryption comprises of a methodology for reversing the process to decode encrypted text, iteratively extracting the decryption components in accordance with the pattern indicator identified for each block of encrypted text, as determined by the pointers, and dependent upon satisfying all user-defined conditions necessary to enable decryption.</p> |
