2016-01-29crypto: Clean up includesPeter Maydell1-0/+1
Clean up includes so that osdep.h is included first and headers which it implies are not included manually. This commit was created with scripts/clean-includes. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Message-id: 1453832250-766-3-git-send-email-peter.maydell@linaro.org
2015-12-23crypto: fix transposed arguments in cipher error messageDaniel P. Berrange1-1/+1
When reporting an incorrect key length for a cipher, we mixed up the actual vs expected arguments. Reviewed-by: Eric Blake <eblake@redhat.com> Signed-off-by: Daniel P. Berrange <berrange@redhat.com>
2015-12-23crypto: move QCryptoCipherAlgorithm/Mode enum definitions into QAPIDaniel P. Berrange1-4/+4
The QCryptoCipherAlgorithm and QCryptoCipherMode enums are defined in the crypto/cipher.h header. In the future some QAPI types will want to reference the hash enums, so move the enum definition into QAPI too. Reviewed-by: Eric Blake <eblake@redhat.com> Signed-off-by: Daniel P. Berrange <berrange@redhat.com>
2015-12-23crypto: add additional query accessors for cipher instancesDaniel P. Berrange1-0/+48
Adds new methods to allow querying the length of the cipher key, block size and initialization vectors. Reviewed-by: Eric Blake <eblake@redhat.com> Signed-off-by: Daniel P. Berrange <berrange@redhat.com>
2015-10-22crypto: allow use of nettle/gcrypt to be selected explicitlyDaniel P. Berrange1-4/+4
Currently the choice of whether to use nettle or gcrypt is made based on what gnutls is linked to. There are times when it is desirable to be able to force build against a specific library. For example, if testing changes to QEMU's crypto code all 3 possible backends need to be checked regardless of what the local gnutls uses. It is also desirable to be able to enable nettle/gcrypt for cipher/hash algorithms, without enabling gnutls for TLS support. This gives two new configure flags, which allow the following possibilities Automatically determine nettle vs gcrypt from what gnutls links to (recommended to minimize number of crypto libraries linked to) ./configure Automatically determine nettle vs gcrypt based on which is installed ./configure --disable-gnutls Force use of nettle ./configure --enable-nettle Force use of gcrypt ./configure --enable-gcrypt Force use of built-in AES & crippled-DES ./configure --disable-nettle --disable-gcrypt Signed-off-by: Daniel P.

2015-07-08crypto: add a nettle cipher implementationDaniel P. Berrange1-2/+4
If we are linking to gnutls already and gnutls is built against nettle, then we should use nettle as a cipher backend in preference to our built-in backend. This will be used when linking against some GNUTLS 2.x versions and all GNUTLS 3.x versions. Signed-off-by: Daniel P.

2015-07-08crypto: introduce generic cipher API & built-in implementationDaniel P. Berrange1-0/+49
Introduce a generic cipher API and an implementation of it that supports only the built-in AES and DES-RFB algorithms. The test suite checks the supported algorithms + modes to validate that every backend implementation is actually correctly complying with the specs. Signed-off-by: Daniel P.
