Works perfectly (Books version 6.4, 6070.12.11), thanks a lot!

A tiny suggestion: It didn't work right away, until I realized I had to quit the Books app first; maybe worth having decrypt.sh run a check or mentioning it in the README.

Some days it works well, but other days it just doesn't work at all with this error
the error i get with decrypt.sh

Failed to extract itemName from /Users/kim/Library/Containers/com.apple.BKAgentService/Data/Documents/iBooks/Books/1234567890.epub

There's a file (1234567890.epub) that can only be opened in Apple Books app located at '/Users/kim/Library/Containers/com.apple.BKAgentService/Data/Documents/iBooks/Books/' btw

I get the following warnings when I run build.sh

injected.m:152:11: warning: format string is not a string literal (potentially insecure) [-Wformat-security] NSLog(baseDirectory); ^~~~~~~~~~~~~ injected.m:152:11: note: treat the string as an argument to avoid this NSLog(baseDirectory); ^ @"%@", injected.m:221:1: warning: non-void function does not return a value in all control paths [-Wreturn-type] }

When I run decrypt.sh I get:
