PowerShell Pro Obfuscator version history

Engine history

v1.0.2 - 30.07.2026

• Self-defending rewritten — opaque body-digest probe (FNV over the normalized on-disk script with the probe span excluded) instead of source-shape / function-count checks
• Integrity / string-decrypt keys are derived from the live body digest; content edits poison those keys
• Detect-debugger no longer clears healthy self-defending keys when both options are enabled

v1.0.1 - 29.07.2026

• Fixed try {} finally {} construct to be compatible with PS5 and PS7

v1.0.0 - 28.07.2026

• Initial release
• Self-defending — source-shape integrity probe; failed tamper checks perturb protected string keys
• Protection linker — runtime decoy calls, honeypot resolvers, and shallow-stack tripwires linked to protected helpers
• Rename variables — rename user variables to random, scope-safe identifiers
• Rename parameters — rename function/filter parameters and their in-body bindings
• Rename functions — rename function/filter definitions and retarget all calls
• Shuffle functions — randomize the order of top-level function definitions
• Control-flow flattening — convert linear code into a switch/while dispatcher
• State machine — dual-state automaton dispatch over linear blocks
• VM virtualization — lower simple statements to micro opcode interpreters
• Encrypt integers — replace integer literals with equivalent arithmetic expressions
• Integers to arrays — extract integer literals into indexed lookup arrays
• Affine integer mask — wrap integers in reversible xor/affine masks
• Integers to floating — express integers via [Math] floating-point expressions
• Encrypt floating — replace float literals with equivalent [Math] expressions
• Floats to arrays — extract float literals into indexed lookup arrays
• Split strings — split string literals into concatenated substrings
• Encrypt strings — runtime polymorphic string decryption helpers
• String char-array vault — encode strings as char-code arrays rebuilt at runtime
• Reflect/invoke commands — build cmdlet names via concatenation and indirect invocation
• Insert dead code — inject inert statements that never affect output
• Complexify booleans — rewrite boolean conditions into equivalent complex forms
• Decoy functions — add unused, plausible-looking decoy function definitions
• Detect debugger — anti-debug guards that exit when a debugger/breakpoint is present
• Fake dot-source markers — add commented fake dot-source dependency markers
• Opaque branches — insert always-false opaque predicate branches between statements
• Scriptblock decoys — prepend inert scriptblock variable bindings
• Literal padding — prepend a large unused here-string to pad size/line numbers
• Try/finally noise — wrap regions in inert try/finally blocks
• Event stub — insert dead event/timer registration stubs
• Remove comments — strip line # and block <# #> comments from output
