goselfshield

GoSelfShield securely embeds and deploys encrypted executables in Go, using passphrase-protected self-replacement for enhanced security.

Usage

Assume you have an unencrypted executable at ./my-executable.

With goselfshield, you can create an encrypted, self-executable installer:

goselfshield --private-key PASSPHRASE --output my-installer --source my-executable

After creation, you can distribute my-installer publicly.

To use the installer, your users need to know the passphrase used during its creation:

./my-installer --installer-private-key PASSPHRASE

Notes:

• Omitting --installer-output causes the installer to replace itself and re-execute itself after successful unpacking.
• Omitting --installer-private-key prompts the user to enter the passphrase from the command line.

Full example

$ goselfshield -output test-executable -source tmp/gomemory --private-key df0f56ae8e54c3e028d37f36d0eda121266bf49f4ef90d34873340b3175177d0
make: Nothing to be done for `all'.
Self-installer created: test-executable
$ ./test-executable --version
INSTALLER: Please enter your private key: df0f56ae8e54c3e028d37f36d0eda121266bf49f4ef90d34873340b3175177d0
INSTALLER: Decrypted to: /Users/jhh/git/hyperifyio/goselfshield/test-executable.tmp
INSTALLER: Backup made successfully to: /Users/jhh/git/hyperifyio/goselfshield/test-executable.bak
