Mike Gelfand 3f9575fcc8 Minor type adjustments (incomplete, it takes way too much time) 2015-03-15 11:43:32 +00:00
Mike Gelfand 748f8a75d2 #4400, #5462: Move SSHA1 helpers to crypto-utils
On a way to factoring out OpenSSL support to a standalone file to ease
addition of other crypto libraries support in the future, move helpers
providing SSHA1 password generation and checking to crypto-utils.{c,h}.

Mike Gelfand 117ab3e8d2 #4400, #5462: Move DH helpers to crypto-utils
On a way to factoring out OpenSSL support to a standalone file to ease
addition of other crypto libraries support in the future, move helpers
providing DH key exchange to crypto-utils.{c,h}. OpenSSL-related
functionality (DH context management) is moved to crypto-utils-openssl.c.
Since we know in advance that DH secret key management code will be the
same for most of backends, implement common functionality in separate
crypto-utils-fallback.c.

Add new tr_dh_ctx_t and tr_dh_secret_t types and functions to be
implemented by crypto backends:
* tr_dh_new - allocate DH context,
* tr_dh_free - free the context,
* tr_dh_make_key - generate private/public keypair,
* tr_dh_agree - perform DH key exchange and generate secret key,
* tr_dh_secret_derive - calculate secret key hash,
* tr_dh_secret_free - free the secret key,
* tr_dh_align_key - align some DH key in the buffer allocated for it.

Make DH secret key not accessible in plain form outside the crypto
backend. This allows for implementations where the key is managed by
the underlying library and is not even exposed to our backend.

Mike Gelfand d424ed143e #4400, #5462: Move RC4 helpers to crypto-utils
On a way to factoring out OpenSSL support to a standalone file to ease
addition of other crypto libraries support in the future, move helpers
providing RC4 ciphering to crypto-utils.{c,h}. OpenSSL-related
functionality (RC4 context management) is moved to crypto-utils-openssl.c.

Add new tr_rc4_ctx_t type and functions to be implemented by crypto
backends:
* tr_rc4_new - allocate RC4 context,
* tr_rc4_free - free the context,
* tr_rc4_set_key - set cipher key,
* tr_rc4_process - cipher memory block.

Mike Gelfand 4cfe7e7ddb #4400, #5462: Move SHA1 helpers to crypto-utils
On a way to factoring out OpenSSL support to a standalone file to ease
addition of other crypto libraries support in the future, move helpers
providing SHA1 calculation to crypto-utils.{c,h}. OpenSSL-related
functionality (SHA1 context management) is moved to crypto-utils-openssl.c.

Add new tr_sha1_ctx_t type and functions to be implemented by crypto
backends:
* tr_sha1_init - allocate SHA1 context and and initialize it,
* tr_sha1_update - hash some [more] data,
* tr_sha1_final - finish hash calculation and free the context.

Add new files to CMakeLists.txt (leftover from previous commit) to fix
CMake-based configuration.

Mike Gelfand f6f7bf8227 #4400, #5462: Move random helpers to crypto-utils
On a way to factoring out OpenSSL support to a standalone file to ease
addition of other crypto libraries support in the future, move helpers
providing random numbers/data generation to crypto-utils.{c,h}. OpenSSL-
related functionality (generation of cryptographically strong random
data) is moved to crypto-utils-openssl.c.

Rename functions to follow currently accepted style:
* tr_cryptoRandBuf -> tr_rand_buffer
* tr_cryptoRandInt -> tr_rand_int
* tr_cryptoWeakRandInt -> tr_rand_int_weak

Fix rare case of invalid value being returned from tr_rand_int. Return
value for abs(INT_MIN) may be undefined and thus negative, and so
tr_rand_int will return negative value which is incorrect (out of
requested and expected range).

Mike Gelfand e30728367f #5771: Use true and false instead of 1 and 0 for bool variables (patch by ticamkq + additional fixes) 2014-11-30 19:38:47 +00:00
Jordan Lee 4bb7f61e31 fix tr_cryptoGetTorrentHash() behavior for crypto-test.c 2014-05-18 20:47:58 +00:00
Jordan Lee 02cff80c2d Copyedit the license's revised text: (1) remove unnecessary repitition use of the word 'license' from the top of the header and source files (2) add the standard 'we hope it's useful, but no warranty' clause to COPYING (3) make explicit that linking OpenSSL is allowed (see https://people.gnome.org/~markmc/openssl-and-the-gpl.html for background) (4) sync the Qt and GTK+ clients' license popups with COPYING's revised text 2014-01-21 03:10:30 +00:00
Jordan Lee 4b9626bb83 Licensing changes:
1. add the option the code to be used under GPLv2 or GPLv3; previously only GPLv2 was allowed

2. add the "proxy option" as described in GPLv3 so we can add future licenses without having to bulk-edit everything again :)

3. remove the awkward "exception for MIT code in Mac client" clause; it was unnecessary and confusing.

Jordan Lee 879a2afcbd Update the copyright year in the source code comments.
The Berne Convention says that the copyright year is moot, so instead of adding another year to each file as in previous years, I've removed the year altogether from the source code comments in libtransmission, gtk, qt, utils, daemon, and cli.

Juliusz's copyright notice in tr-dht and Johannes' copyright notice in tr-lpd have been left alone; it didn't seem appropriate to modify them.
