Toasted golden, schmeared with insight. Top of the rack.
Summary
SpiceCrypt is a Python library and command-line tool designed to decrypt encrypted SPICE model files used in electronic circuit simulation. The tool supports LTspice and PSpice encryption formats with automatic format detection, enabling engineers to use legally obtained models across different simulators. It includes features for handling PSpice Mode 4 encryption (which uses user-supplied keys) and provides installation via PyPI with various package management options.
