This short script aims to use bsdiff's implementations in C and Go to create a diff/patch file from two related binaries and successfully regenerate the latest from the earliest + the diff file.
Build the bspatch.c file in order to recreate the latest file.
cd bsdiff-4.3 && make
Create diff file:
go run main.go earliest-file.ext latest-file.ext diff-file.ext
Recreate latest file from diff:
bsdiff-4.3/bspatch earliest-file.ext generated-latest-file.ext diff-file.ext
