#4 Enhance the encryption to be more than XOR

[ojblass]

Currently the encryption can be easily cracked using primitive methods and statistical distribution analysis on the 'obfuscated' scripts.

[gits]

yet more simple than that, here is a oneliner

awk 'BEGIN{for(i=0;i<=127;i++)[sprintf("%c",i)]=i}NR==1&&/decrypt/{next}{n=split($0,a,//);s="";for(i=1;i<=n;i++)s=s sprintf("%c",xor([a[i]],0xc));printf "%s\n", s}'
