Greetings,
Block ciphers & Stream-Based are the two methods of cryptography
Symmetric & Asymmetric are two forms of cryptography  
(ISC2) Official Page 236

Point is, what if you have a question that goes like:

What are the most important encryption methods:

1. symmetric, asymmetric

2. block, stream

It is a BAD question I know but still I am sure I rember I had a question
like this one somewhere.

Moreover, is this the likely to be the level of trickery the CISSP can
present ? Unfortunately I don't know and this is the reason why I am
scratching my head everytime I find inconsistences.

Methods is a flexible term and can be used in many ways when referring to

Clement, list -
I do understand the the official guide is clearly not accurate. Words cannot
describe how angry I am...Nevertheless - at least for my own peace of mind -
I would like to throw another one from the guide:

" Encryption methods"

Shon Harris AIO - Page 679

"Methods of encryption"

As far as I can say as for as Shon is concerned 'methods' refers to
symmetric vs. asymmentric

Official ISC2 guide - Page 227

"Methods of Cryptography"

Here for "methods" the author refers to block vs stream ciphers

Thanks,
Andrea
