High entropy strings
Web21 de mai. de 2015 · In this paper, we study the conical entropy in string theory in the simplest setup of dividing the nine dimensional space into two halves. This corresponds to the leading quantum correction to the horizon entropy in string theory on the Rindler space. This entropy is also called the conical entropy and includes surface term contributions. … Web18 de ago. de 2011 · 11 Answers Sorted by: 35 Initialize an array containing all the accepted chars ( CHARS_ARRAY ), then instantiate a SecureRandom instance, and call nextInt (CHARS_ARRAY.length) repeatedly to get a random index in your char array.

WebFor entropy checks, truffleHog will evaluate the shannon entropy for both the base64 char set and hexidecimal char set for every blob of text greater than 20 characters comprised of those character sets in each diff. If at any point a high entropy string >20 characters is detected, it will print to the screen. Help WebRight now my code is like this: import math def shannon (string): prob = [ float (string.count (c)) / len (string) for c in dict.fromkeys (list (string)) ] entropy = sum ( [ p * math.log (p) / math.log (2.0) for p in prob ]) return entropy.

You could use an existing hash algorithm that produces something short, like MD5 (128 bits) or SHA1 (160). Then you can shorten that further by XORing sections of the digest with other sections. This will increase the chance of collisions, but not as bad as simply truncating the digest.
