How to get the fingerprint of a pdf

[Derek Thomas]

Hello,

My workflow is to annotate zotero pdfs (and sometimes articles) and import them into obsidian.md. Im writing a script which will combine zotero info on my pdfs and hypothesis annotations to be used in obsidian and automatically converted into anki cards. 

Im stuck as I am having a hard time iterating through my zotero library and linking the pdfs to hypothes.is. Zotero does not have a digital fingerprint. Is there a way with python I can get the digital fingerprint of a pdf? 

Thanks, Derek​

Hello Derek,

You're in luck. One of our developers wrote a blog post on this topic: https://www.seanh.cc/2017/11/22/pdf-fingerprinting/
