Right now, dynamic does limit to 80 bytes, but I do plan on opening that up to 119 bytes (111 bytes for SHA512 when I get there). > 3. The SHA1 was an 'oddball' in the large format, and had many nuances (mostly were very bad), making it much harder to design proper formats to operate optimally. > 4. The changes make writing a script in an optimal way, very straight forward. The original implementations of the "Waffle" hashes, I redid some, and got 20-40% improvement in speed. I had to somewhat undo some of those changes, with the new layout, and again got 15-20% improvement in speed, over and above the improvements I obtained the first time. I never have any idea what you're talking about :p But I know faster is better, and you work hard at making all these changes. It is appreciated, keep up the good work :) </brown-nose> -rich
