Closes#1084
* os400: support QADRT development files in a non-standard directory
This enables the possibility to compile libssh2 even if the ascii
runtime development files are not installed system-wide.
* userauth_kbd_packet: fix a pointer target type mismatch.
A temporary variable matching the parameter type is used before copying
to the real target and checking for overflow (that should not occur!).
* os400qc3: move and fix big number procedures
A bug added by a previous code style cleaning is fixed.
_libssh2_random() now checks and return the success status.
* os400qc3: fix cipher definition block lengths
They were wrongly set to the key size.
* Diffie-Hellman min/max modulus sizes are dependent of crypto-backend
In particular, os400qc3 limits the maximum group size to 2048-bits.
Move definitions of these parameters to crypto backend header files.
* kex: return an error if Diffie-Hellman key pair generation fails
* os400: add an ascii assert.h header file
* os400qc3: implement RSA SHA2 256/512
* os400: minimum supported OS version is now V6R1.
Do not log compiler informational messages.
* Implement crypto backend specific Diffie-Hellman computation.
This feature is now needed on os400 because the QC3 library does not
implement bn_mod_exp() natively. Up to now, this function was emulated using
an RSA encryption, but commits ca5222ea81 and
7934c9ce2a (CVE-2016-0787) broke the emulation
because QC3 only supports RSA exponents up to 512 bits.
Happily, QC3 supports a native API for Diffie-Hellman computation, with
opaque random value: this commit implements the use of this API and, as a
side effect, enables support of this feature for any other crypto backend that
would use it.
A "generic" Diffie-Hellman computation internal API supports crypto backends
not implementing their own: this generic API uses the same functions as before.
* Fix typos in docs/HACKING.CRYPTO.
