Validation tools are essential to document the integrity and validity of both your data and methods. They can assure that your findings will withstand close scrutiny and legal challenges. We offer the following:

• Crc CD
• Files CD
• Hash Set CD

The Crc CD contains files and procedures (batch files) designed for testing the operation of the following:

1. Programs that calculate CCITT CRC32, MD5 HASH, or 160 bit SHA-1.
2. The ability of your CD writer to copy files correctly.
3. The ability of your software to properly process data files.

This CD contains known files and the values that CRC, MD5 and SHA-1 should produce. Therefore, you can use these files as a test platform to verify the output of your program by running it against these known entities.

Because this CD contains known entities, it can also be used to test the copy integity of your CD rom drive or other hardware. What goes in should come out.

Also contained on the CD is information on where to obtain additional, independent programs which calculate these values(should you want to cross-validate your findings).

The Crc CD is priced at $20. (U.S. Dollars)
