Take the 2-minute tour ×  I'm using owasp EnDe web-based tool to
understand nibbles and encoding in general. This online utility
in my knowledge is the best free resource avaiable for anyone
who is interested to learn encoding techniques.  I'm testing a
sample input which is abcdwxyz.  Now, the results of encoding it
based upon first nibble and second nibble is given as
36,1,36,2,36,3,36,4,37,7,37,8,37,9,37,A and
6,31,6,32,6,33,6,34,7,37,7,38,7,39,7,61 respectively.  A simple
representation in hex of above sample input is 61 62 63 64 77 78
79 7a .  Can someone explain how it relates to the use in this
tool?  For those who are interested in download owasp live cd
here is the link http://appseclive.org/content/downloads   With
some help from guys at stackexchange sisters I'm able to figured
out the messy stuff. The whole encoding works like this.
Actually i was confusing in nibble 1 and nibble 2 definition in
the tool. In theory nibble 1 should refer to high nibble and
nibble 2 as low nibble. I was just confus
