Very good book, finally I understand a little better what you like on mathematics and what you need Sage for. :) Will the book be available online, or do I need to save the copy now? As a fan, who enjoyes this kind of stuff, but does not do this for living, I especially like that you wrote those encode/decode methods for actually turning messages to numbers. Only I found a little confusing why you first explain this using the base 27, while the implementation uses the base 256 (obviously), but that's minor. I was actualy always wondering how hard would it to add to Sage the functionality to take some gpg encrypted message and turn it into the numbers that you talk about, so that one can play with it, and at the end turn this into the gpg message again, so that one can verify that it really does work as written in the docs, or coded in the gpg program. E.g. so that one can receive a gpg encrypted message (I do get those in Debian from time to time) and then take my private key, import those in Sage as numbers and then decode the message by "hand". This would make me think that I really understand how it works. :) Ondrej --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-devel@googlegroups.com To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-devel URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
