Comment (by Jigsaw52):

 I tried to fix this. Here is my code: https://github.com/Jigsaw52/tor/tree
 /remove-padding-fix-7869

 While fixing this issue, I noticed that the function
 curve25519_public_to_base64 does not behave according to its description.
 The description says 'Encode <b>pkey</b> as a base64-encoded string,
 without trailing "=" characters'. However, this function output still had
 the trailing "=".
 I fixed this as well and fixed all the code and tests that used padded
 keys.
