commit d82a70a4fb874ca295c1644e3c77f24afddcbf06 Author: Damian Johnson <atagar(a)torproject.org> Date: Wed Nov 28 21:16:04 2012 -0800 Minor whitespace changes Just adding empty lines in a few spots to improve readability.

commit e0095fbe54759c45cbf6d1b120d2b17b47a0ec21 Author: Eoin o Fearghail <eoin.o.fearghail(a)gmail.com> Date: Fri Nov 23 22:16:22 2012 +0000 Implementing Relay Descriptor verification cf https://trac.torproject.org/projects/tor/ticket/5810 1) Implemented relay descriptor verification using the python-crypto lib. Code is only run if python-crypto can be imported. [cf stem.prereq.is_crypto_available()] NOTE: constructing a RelayDescriptor will now raise an exception if invalid descriptor content is used. 2) Refactored the digest() function in server_descriptor.py. 3) Added a function to the mocking lib to sign a descriptor with an auto-generated key 4) Add usage of new sign_descriptor_content() in unit tests where necessary. 5) Updated the non-ascii-descriptor file to be correctly signed. 6) Updated extra info descriptor test to use new fingerprint in non-ascii-descriptor file 7) Removed server descriptor tests that do not make sense if data is being generated dynamically. e.g. Removed test fingerprint valid test, since data now dynamically generated. --- stem/descriptor/server_descriptor.py | 144 +++++++++++++++++------ stem/prereq.py | 23 ++-- test/integ/descriptor/data/non-ascii_descriptor | 14 +- test/integ/descriptor/server_descriptor.py | 4 +- test/mocking.py | 85 +++++++++++++ test/unit/descriptor/server_descriptor.py | 23 +--- test/unit/tutorial.py | 8 +- 7 files changed, 223 insertions(+), 78 deletions(-) diff --git a/stem/descriptor/server_descriptor.py b/stem/descriptor/server_descriptor.py index 046dfe1..9f3dbb3 100644 --- a/stem/descriptor/server_descriptor.py +++ b/stem/descriptor/server_descriptor.py @@ -39,6 +39,7 @@ import stem.exit_policy import stem.version import stem.util.connection import stem.util.tor_tools +import stem.util.log as log # relay descriptors must have exactly one of the following REQUIRED_FIELDS = ( @@ -593,52 +594,123 @@ class RelayDescriptor(ServerDescriptor): super(RelayDescriptor, self).__init__(raw_contents, validate, annotations) - # if we have a fingerprint then checks that our fingerprint is a hash of - # our signing key + # validate the descriptor if required + if validate: + # ensure the digest of the descriptor has been calculated + self.digest() + self._validate_content() + + def digest(self): + # Digest is calculated from everything in the + # descriptor except the router-signature. + raw_descriptor = str(self) + start_token = "router " + sig_token = "\nrouter-signature\n" + start = raw_descriptor.find(start_token) + sig_start = raw_descriptor.find(sig_token) + end = sig_start + len(sig_token) + if start >= 0 and sig_start > 0 and end > start: + for_digest = raw_descriptor[start:end] + digest_hash = hashlib.sha1(for_digest) + self._digest = digest_hash.hexdigest() + else: + log.warn("unable to calculate digest for descriptor") + raise ValueError("unable to calculate digest for descriptor") - if validate and self.fingerprint and stem.prereq.is_rsa_available(): - import rsa - pubkey = rsa.PublicKey.load_pkcs1(self.signing_key) - der_encoded = pubkey.save_pkcs1(format = "DER") - key_hash = hashlib.sha1(der_encoded).hexdigest() - - if key_hash != self.fingerprint.lower(): - raise ValueError("Hash of our signing key doesn't match our fingerprint.
