Abstract

The purpose of this document is to make the Advanced Encryption Standard (AES) Key Wrap algorithm conveniently available to the Internet community. The United States of America has adopted AES as the new encryption standard. The AES Key Wrap algorithm will probably be adopted by the USA for encryption of AES keys. The authors took most of the text in this document from the draft AES Key Wrap posted by NIST.

This text was extracted from an ASCII text file.
This is the abbreviated version, containing approximately 4% of the total text.
