rtmpdh: Don't use the OpenSSL DH struct
Merged-by: Clément Bœsch <u@pkh.me>
|
|
Instead use our own struct, which we already use when using
gcrypt and gnutls.
In OpenSSL 1.1, the DH struct has been made opaque.

testprogs: Clean up #includes
Merged-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>
|
|
This avoids spurious library rebuilds when only the test program
code is changed and simplifies the build system.
|
|
The test uses printf.

Either disabling or init'ing secure memory is required after the use
of gcry_check_version. From a look at the functions rtmpdh uses, I
noticed none require the use of secure memory, so we disable it [1][2].
This resolves some errors returned by rtmpdh code with uninitialized
gcrypt, especifically:
Fatal: failed to create the RNG lock: Invalid argument
FATAL: failed to acquire the FSM lock in libgrypt: Invalid argument
Version "1.5.4" was arbitrarily chosen. An older version probably works
as well, but I couldn't compile older versions to test on my machine.

* commit '63ce9fd23cfa5ac0d9a862be0da138108dc1c505':
rtmpdh: Use GMP functions directly, instead of nettle wrappers
Merged-by: Michael Niedermayer <michaelni@gmx.at>
|
|
mpz_import and mpz_export were added in GMP 4.1, in 2002.
This simplifies the DH code by clarifying that it only uses pure
bignum functions, no other parts of nettle/hogweed.

This helps if these functions need to be implemented using another
crypto API.

This adds two protocols, but one of them is an internal implementation
detail just used as an abstraction layer/generalization in the code. The
RTMPE protocol implementation uses ffrtmpcrypt:// as an alternative to the
tcp:// protocol. This allows moving most of the lower level logic out
from the higher level generic rtmp code.
