+# peinfo-go
+
+This is a PE (Portable Executable) parser written in GoLang. I wanted to learn more about the PE format, specifically how the certificates were stored. What better way is there than to write some code?
+
+_This is a work in progress and will continue to change._
+
+This leverages the `debug/pe` package for parsing of the common headers/sections.
+
+Current state:
+- Displays some PE details
+- Validates certificate, verifies certificate chain, checks against CRL
+- Parses Version Info struct
+- Displays imports
+
+TODO:
+- ~~Actually Parse Version Info struct (currently displayed as raw binary)~~
+- Re-write function for finding Version Info (currently written so I could better understand the structure)
+- ~~Custom certificate stores~~
+
+## Example
+```
