Trusted TimeStamping for Oracle® DatabasesSMExecutive SummaryProving authenticity of electronic records and digital events is emerging as a significant and costly IT, legal and business issue. In ... [More] fact, following the past decade of corporate scandals, the courts and regulators are increasingly requiring organizations to demonstrate the authenticity of their business records. While Oracle employs world-class security and backup strategies to protect your data, it does not include a native mechanism that enables you to unequivocally PROVE that your sensitive data was what you claim it was at a given point in time. Trusted Timestamping for Oracle Databases is an open source PL/SQL add-in that provides this highest possible level of data integrity assurance by integrating state-of-the-art cryptographic tamper detection algorithms into your Oracle database. Using trusted timestamping solutions like ProofSpace's patented ProofMark™ Transient KeySM technology, users can instantly prove the authenticity of any electronic record. Much like the tamper seal found on a bottle of aspirin, a trusted timestamp locks in the integrity of important electronic records, detects unauthorized changes and enables you to prove authenticity to regulators, auditors, trading partners and counsel. Because trusted timestamps are tamper-proof and portable, they can be shared with electronic trading partners to create a new level of trust and dependability. Sample applications include certification of financial transactions, sales & purchase orders, legal documents, medical records, student records and HR data stored in Oracle databases. Key benefits include reducing risk, minimizing compliance and legal expenses, and enhancing counterparty trust through the highest possible level of Oracle data integrity assurance. Technical OverviewTrusted Timestamping for Oracle provides a real-time, database-embedded XML-over-HTTP interface to a Trusted Timestamp server for issuing and verifying irrefutable and portable Trusted Timestamps that protect the integrity of sensitive records stored in your Oracle database. These XML “seals of authenticity” can be shared with trading partners and are easily archived with your data for long-term storage and later authenticity verification, even in the very distant future. Open Source Package Includes:Trusted Timestamp Request Broker — a PL/SQL package that handles both Issuance & Verification of Trusted Timestamps Audit Trail Repository which logs changes to end user data and stores the associated Trusted Timestamps and Verfication Reports Simplified end user layer for custom reporting Installation Guide Database audit trigger template that can be used to create audit triggers on your application's tables. System Requirements:Oracle Database 10g or 11g (all editions except XE) Network connectivity to a Trusted Timestamp server, such as a ProofSpace ProofMark Server (licensed separately from ProofSpace). Product Development Road MapDevelopment goals for future releases include: More robust error and exception handling Support for additional Time Stamp Authorities (TSAs) Graphical User Interface Developers interested in improving the product are welcome to become involved with this project!

DescriptionPython based salt bruteforcer for known hashes. Useful when you want to find out how a certain application hashes its passwords when you have both the password and the hash. This project is ... [More] still in its inception but we plan on supporting more hashes and complex functions in the near future. For example, you were able to obtain a list of application password hashes stored in a database, including your own. To be able to brute force for other users' passwords you would first need to know how the application hashes these passwords. Salty-py attempts to guess the salt used to hash the passwords by prepending/appending user supplied salt and comparing the resultant hash to the known hash. Example usagepython salty-py -a MD5 -p password -r 9e107d9d372bb6826bd81d3542a419d6 -w wordlist.txt [Less]

General InfoThis project allows the user to hash / encrypt / decrypt a list of directories / files. The user can drag and drop and/or choose via a browser which files / folders he needs to crypt. The ... [More] selection allows for MD5, SHA1, SHA128, SHA256, SHA512 hashing which is saved in a CSV file and/or for AES encryption based on the user's keyed-in phrase. [Less]
