Jeremy, I must commend you for your helpfulness and cooperation. Not being a professional cryptographer, I believe that your algorithms are not very strong, but I will be happy if you and others prove me wrong. Actions such as yours inspire trust in the cryptographic software that you write, if it passes the review. Thank you. - Igor. DataETRsch@aol.com wrote:

50,000 with the same key? Sure. A new file will be posted under the same name as the previously posted one. The same key will be used to encrypt the file before posting. Contest details will be reposted. By the way, a simple VSA2048 decryption program will be released soon so that there will not exist a need to develop one to decrypt the file. Also, the contest expiration date has been extended to July 1st, 1997. Good luck!

Again, random XOR is *not* the only method used to encrypt data. In fact, random XOR could be left out. Consider examining VSACMInternal (in INTUNIT.PAS) and VSACMProcessOperation in LIBUNIT.PAS for additional information.
