Reverse project for libmecl.so (MCBook). Currently only support encryption type 5 (AES + mocha).

./mecl.py mybook.epubx

Example output:

Found da2 file 0001/Text/aText.dat
Attempting decryption (may take a while for large books due to slow implementation)
Decrypted to 0001/Text/aText.dat.plaintext

• Test on more books.
• Support other encryption types.
• Support other book assets than text.
