Nick Mathewson	92acbe12bc	Refactor common file code into util.c; add published to descriptors ... svn:r487	2003-09-26 18:27:35 +00:00
Nick Mathewson	3d4ccb781a	Refactor buffers; implement descriptors. ... 'buf_t' is now an opaque type defined in buffers.c . Router descriptors now include all keys; routers generate keys as needed on startup (in a newly defined "data directory"), and generate their own descriptors. Descriptors are now self-signed. Implementation is not complete: descriptors are never published; and upon receiving a descriptor, the directory doesn't do anything with it. At least "routers.or" and orkeygen are now obsolete, BTW. svn:r483	2003-09-25 05:17:11 +00:00
Nick Mathewson	e4dfc3c8fe	Cipher lists need to be colon separated. Also make initialization more bulletproof ... svn:r459	2003-09-15 19:38:52 +00:00
Nick Mathewson	f5b4ef1fa2	Simplify some code paths in TLS; cut down on memory leaks; use ... reasonable ciphers if not everyone has OpenSSL 0.9.7. svn:r442	2003-09-11 21:12:39 +00:00
Nick Mathewson	9955b265ab	Make crypto structures private to crypto.c ... svn:r437	2003-09-10 00:47:24 +00:00
Nick Mathewson	fd20011c26	Add initial interfaces and code for TLS support. Interfaces are right; code needs work and testing. ... svn:r424	2003-09-04 16:05:08 +00:00
Roger Dingledine	58c5d5e918	fix formatting in crypto.c for my sanity ... svn:r411	2003-08-25 07:06:12 +00:00
Nick Mathewson	c336c99e60	Start of port to win32. Missing are: ... - signal support - forking for DNS farm - changes for async IO - daemonizing In other words, some files still don't build, and the ones that do build, do nonblocking IO incorrectly. I'm also not checking in the project files till I have a good place for them. svn:r380	2003-08-12 03:08:41 +00:00
Nick Mathewson	f12fdd62aa	Be smarter about getting key matter from DH. ... Formerly, once we had g^xy, we took the last N bytes from g^xy. Now, we take SHA(g^xy || [0]) || SHA1(g^xy || [1]) || ... , in order to use all bits from g^xy equally, and generate as much key material as we need. svn:r370	2003-07-30 19:10:20 +00:00
Nick Mathewson	300984c057	Add AES counter-mode support to the crypt library ... svn:r362	2003-06-30 19:18:32 +00:00

Nick Mathewson	769c78a395	Use fread instead of fgets for binary data ... svn:r328	2003-06-17 20:19:41 +00:00
Nick Mathewson	9182537238	Fix the periodic bug that would make handshaking fail. ... The culprit: sometimes DH_calculate_key returns less than DH_KEY_LEN bytes; we needed to check the return value. svn:r322	2003-06-14 01:30:53 +00:00
Nick Mathewson	d21c0feb5a	Add RNG seeding ... svn:r318	2003-06-13 21:13:37 +00:00

Roger Dingledine	59029a3eed	replace malloc with tor_malloc; remove broken/unused crypto_pk_set_key ... svn:r292	2003-05-20 06:37:34 +00:00
Nick Mathewson	afc0eb2c71	Tested backends for directory signing and checking. Directory parser completely refactored. Need documentation and integration. Explanitory mail forthcoming. ... svn:r271	2003-05-07 18:30:46 +00:00
Nick Mathewson	445cd8f0f1	Decrease DH group length to 1024. (Roger, you may want to read section 1 of the IETF draft: a 1024-bit DH key probably reduces our cipher strength to ~80 bits.) ... svn:r269	2003-05-07 02:28:42 +00:00
Nick Mathewson	d0ff485e1b	More work on directories. Signed directories not yet tested. No support for checking sigs yet ... svn:r268	2003-05-07 02:13:23 +00:00

Roger Dingledine	2fa4b5bb53	don't leak memory on pk ops ... svn:r117	2002-09-27 22:13:22 +00:00
Roger Dingledine	253f0f160e	laying the groundwork for dynamic router lists ... revamped the router reading section reference counting for crypto pk env's (so we can dup them) we now read and write pem pk keys from string rather than from FILE*, in anticipation of fetching directories over a socket (so now on startup we slurp in the whole file, then parse it as a string) fixed a bug in the proxy side, where you could get some circuits wedged if they showed up while the connection was being made svn:r110	2002-09-24 10:43:57 +00:00
Roger Dingledine	f9f3e2f120	slight optimization on rsa exponent ... use 2**16+1 rather than 2**16 + 2**(-1) svn:r99	2002-09-05 19:04:47 +00:00

Matej Pjafjar	01aadefbfc	Changed crypto calls to go through common/crypto.[hc] instead of calling OpenSSL directly. ... svn:r76	2002-08-22 07:30:03 +00:00
Matej Pjafjar	e01522bbed	Added the crypto abstraction to libor. Need to test and change the code to use this instead of OpenSSL. ... svn:r74	2002-07-25 08:17:22 +00:00
