commit 70591e63fc7773db42d457b4e97d37236791d323 Author: Damian Johnson <atagar(a)torproject.org> Date: Sat Feb 28 15:10:07 2015 -0800 Encrypted introduction-points test data Including examples of hidden service descriptors with encrypted introduction-points fields from #15004. We don't yet have support for decrypting the fields, but at least we can assert that we raise the expected exception when it's encrypted. --- .../unit/descriptor/data/… [View
