CSE-470 Cryptography and Computer Security

Implementation of Sparkle lightweight symmetric cryptographic algorithm with different functionalities and different modes (ECB, CBC, OFB and CBC)
Implementation also contains tools in order to understand that any document (.doc/.docx, .pdf, ppt, xls etc.) has not been modified and determined by the creator, it takes the extract and encrypt it with a key that only the person who made the transaction reaches and appends it to the end of the file.
To check that the overall file has not changed, it also performs the comparative verification tool with the hash value produced by performing the operations.
