camellia-ntt had none of its symbols renamed into the hc_ namespace,
and rand's missed timer_method (while all other methods were done). rename
these like we do for others
This adds a new backend for libhcrypto: the OpenSSL backend.
Now libhcrypto has these backends:
- hcrypto itself (i.e., the algorithms coded in lib/hcrypto)
- Common Crypto (OS X)
- PKCS#11 (specifically for Solaris, but not Solaris-specific)
- Windows CNG (Windows)
- OpenSSL (generic)
The ./configure --with-openssl=... option no longer disables the use of
hcrypto. Instead it enables the use of OpenSSL as a (and the default)
backend in libhcrypto. The libhcrypto framework is now always used.
OpenSSL should no longer be used directly within Heimdal, except in the
OpenSSL hcrypto backend itself, and files where elliptic curve (EC)
crypto is needed.
Because libhcrypto's EC support is incomplete, we can only use OpenSSL
for EC. Currently that means separating all EC-using code so that it
does not use hcrypto, thus the libhx509/hxtool and PKINIT EC code has
been moved out of the files it used to be in.
The EGD daemon is completely unmaintained and has not seen a release
since 13 years which is not an acceptable timeframe for cryptographic
software. It is not packaged in any linux distribution I know of
and definitely not in *BSD.
LibreSSL has already dropped support for RAND_egd.
rand.h doesn't require any symbols defined in bn.h, so don't
include bn.h in the header file. This makes it easier for applications
to include only the symmetric portions of libhcrypto.
