Definition at line 64 of file pccrc_test.c.

◆ PEERDIST_INFO_TEST

#define PEERDIST_INFO_TEST	(	name,
		DATA,
		DIGEST,
		DIGESTSIZE,
		RANGE,
		TRIM,
		SEGMENTS
	)

Value:

static const uint8_t name ## _data[] = DATA;                    \
        static struct peerdist_info_test name = {                       \
                .data = name ## _data,                                  \
                .len = sizeof ( name ## _data ),                        \
                .expected_digest = DIGEST,                              \
                .expected_digestsize = DIGESTSIZE,                      \

                .expected_segments = SEGMENTS,                          \
        }

Define a content information test.

Parameters

name	Test name
DATA	Raw content information
DIGEST	Expected digest algorithm
DIGESTSIZE	Expected digest size
RANGE	Expected content range
TRIM	Expected trimmer content range
SEGMENTS	Expected number of segments

Return values

test	Content information test

Raw content information can be obtained from PeerDist-capable web servers using wget's "--header" option to inject the relevant PeerDist headers. For example:

wget –header "Accept-Encoding: peerdist" \ –header "X-P2P-PeerDist: Version=1.0" \ http://peerdist.server.address/test.url -O - | xxd -i -c 11

Version 1 content information can be retrieved using the headers:

Accept-Encoding: peerdist X-P2P-PeerDist: Version=1.0

Version 2 content information can be retrieved (from compatible servers) using the headers:

Accept-Encoding: peerdist X-P2P-PeerDist: Version=1.1 X-P2P-PeerDistEx: MinContentInformation=2.0, MaxContentInformation=2.0

#define SERVER_PASSPHRASE	(	name,
		DATA
	)	static uint8_t name[] = DATA

Define a server passphrase.

Parameters

name	Server passphrase name
DATA	Raw server passphrase

The server passphrase can be exported from a Windows BranchCache server using the command:

netsh branchcache exportkey exported.key somepassword

and this encrypted exported key can be decrypted using the oSSL_key_dx or mcrypt_key_dx utilities found in the (prototype) Prequel project at https://fedorahosted.org/prequel/ :

oSSL_key_dx exported.key somepassword or mcrypt_key_dx exported.key somepassword

Either command will display both the server passphrase and the "Server Secret". Note that this latter is the version 1 server secret (i.e. the SHA-256 of the server passphrase); the corresponding version 2 server secret can be obtained by calculating the truncated SHA-512 of the server passphrase.

We do not know the server passphrase during normal operation. We use it in the self-tests only to check for typos and other errors in the test vectors, by checking that the segment secret defined in a content information segment test is as expected.
