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.
