Advanced Encryption Standard (AES) Key Wrap Algorithm
The purpose of this document is to make the 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.
