Jacksum Hacks

Tip

Jacksum's primary purpose is to deal with hashes. However, since Jacksum supports both many encodings and customized formatting you get additional features that can be quite useful sometimes. The Jacksum Hacks were not planned. I was also quite surprised about this side effect which works pretty well.

For all examples below we set -a none, because we are not interested in hashing at all.

File dumps

Hex dump

$ jacksum -a none -q file:myfile.dat -F "#SEQUENCE" -E hex -g 1
4a 61 63 6b 73 75 6d

Base64 dump

$ jacksum -a none -q file:myfile.dat -F "#SEQUENCE{base64}
SmFja3N1bQ==

Z85 dump

$ jacksum -a none -q file:myfile.dat -F "#SEQUENCE{z85}
n)#jBB9hs

Working with strings ...

Count characters of a string

48 65 6c 6c 6f 20 57 6f 72 6c 64

Formatted string to hex

$ jacksum -a none -q "txtf:Hello World\n" -F #SEQUENCE -E hex -g 1
