[CRYPTO] api: Fixed crypto_*_reqsize return type

2007-10-10T23:55:42+00:00

This patch changes the return type of crypto_*_reqsize from int to
unsigned int which matches what the underlying type is (and should
be).

[CRYPTO] ablkcipher: Remove queue pointer from common alg object

2007-10-10T23:55:41+00:00

Since not everyone needs a queue pointer and those who need it can
always get it from the context anyway the queue pointer in the
common alg object is redundant.

[CRYPTO] api: Add support for multiple template parameters

2007-10-10T23:55:40+00:00

This patch adds support for having multiple parameters to
a template, separated by a comma.  It also adds support
for integer parameters in addition to the current algorithm
parameter type.

This will be used by the authenc template which will have
four parameters: the authentication algorithm, the encryption
algorithm, the authentication size and the encryption key
length.

[CRYPTO] api: Add aead crypto type

2007-10-10T23:55:39+00:00

This patch adds crypto_aead which is the interface for AEAD
(Authenticated Encryption with Associated Data) algorithms.

AEAD algorithms perform authentication and encryption in one
step.  Traditionally users (such as IPsec) would use two
different crypto algorithms to perform these.  With AEAD
this comes down to one algorithm and one operation.

Of course if traditional algorithms were used we'd still
be doing two operations underneath.  However, real AEAD
algorithms may allow the underlying operations to be
optimised as well.

[CRYPTO] api: Add ablkcipher_request_set_tfm

2007-05-02T04:38:33+00:00

This patch adds ablkcipher_request_set_tfm for those users that need
to manage the memory for ablkcipher requests directly.

[CRYPTO] api: Add async blkcipher type

2007-05-02T04:38:31+00:00

This patch adds the mid-level interface for asynchronous block ciphers.
It also includes a generic queueing mechanism that can be used by other
asynchronous crypto operations in future.

[CRYPTO] templates: Pass type/mask when creating instances

2007-05-02T04:38:31+00:00

This patch passes the type/mask along when constructing instances of
templates.  This is in preparation for templates that may support
multiple types of instances depending on what is requested.  For example,
the planned software async crypto driver will use this construct.

For the moment this allows us to check whether the instance constructed
is of the correct type and avoid returning success if the type does not
match.

[CRYPTO] api: Add async block cipher interface

2007-05-02T04:38:30+00:00

This patch adds the frontend interface for asynchronous block ciphers.
In addition to the usual block cipher parameters, there is a callback
function pointer and a data pointer.  The callback will be invoked only
if the encrypt/decrypt handlers return -EINPROGRESS.  In other words,
if the return value of zero the completion handler (or the equivalent
code) needs to be invoked by the caller.

The request structure is allocated and freed by the caller.  Its size
is determined by calling crypto_ablkcipher_reqsize().  The helpers
ablkcipher_request_alloc/ablkcipher_request_free can be used to manage
the memory for a request.
