Book cover

This book describes the design and development of the Twofish block cipher, and all known cryptanalytical results up to the time of writing (nov. 1998). Due to the copyright issues involved in book publishing I cannot put the contents of the book on this web site. However, much of the information is available in the form of the AES submission.

You can order the book from Amazon, Amazon.co.uk, or Barnes & Noble
