1484956 - NSSBase64_DecodeBuffer is missing from nss3.dll in 32 and 64 bit build for Windows

Status: RESOLVED WONTFIX

(NSS :: Build, defect)

Description

[Lakatos.Isti]

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/68.0.3440.106 Safari/537.36

Steps to reproduce:

A lot of code that imports saved passwords from a users profile relies on the NSSBase64_DecodeBuffer function exported from nss3.dll to safely decode encrypted usernames and passwords form their json/sqlite storage.


Actual results:

NSSBase64_DecodeBuffer is not exported in nss3.dll in Firefox version 61 on Windows. I have not checked, but it has probably been missing for a few versions.
Searching I've found mentions of it missing since 25th of December 2017

Expected results:

As far as I can tell the function still exists in the NSS codebase on github 
https://github.com/servo/nss/blob/master/lib/util/nssb64d.c
and is even exported in the .def file
https://github.com/servo/nss/blob/master/lib/nss/nss.def

So the function should not be missing.

Please correct if this is not the right component. Thanks.

Firefox only exports functions from nss3.dll that Firefox itself needs; if you need other functions, you will have to supply your own copy of NSS.
