I did OPSDIR review for this document. Such reviews are primarily intended to check if there is any operational or network 


management impact. I do not see any such impact/aspects in the document, so I think the doc is ready for publication from this 


perspective. Some nits/questions: - Section: 5.2. PBKDFs should that be: 5.2. PBKDF2 ??? - I am somewhat surprised to see that ALL 


references are normative. even a reference to a slide deck:


[WANG] X. Wang, A.C. Yao, and F. Yao. Cryptanalysis on SHA-1. Presented by Adi Shamir at the rump session of CRYPTO 2005. Slides may 


be found currently at <
