[CRYPTO] cryptd: Add software async crypto daemon

2007-05-02T04:38:32Z

This patch adds the cryptd module which is a template that takes a synchronous software crypto algorithm and converts it to an asynchronous one by executing it in a kernel thread. Signed-off-by: Herbert Xu

[CRYPTO] api: Do not remove users unless new algorithm matches

2007-05-02T04:38:32Z

As it is whenever a new algorithm with the same name is registered users of the old algorithm will be removed so that they can take advantage of the new algorithm. This presents a problem when the new algorithm is not equivalent to the old algorithm. In particular, the new algorithm might only function on top of the existing one. Hence we should not remove users unless they can make use of the new algorithm. Signed-off-by: Herbert Xu

[CRYPTO] api: Add async blkcipher type

2007-05-02T04:38:31Z

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. Signed-off-by: Herbert Xu

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

2007-05-02T04:38:31Z

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. Signed-off-by: Herbert Xu

[CRYPTO] api: Allow multiple frontends per backend

2007-02-06T22:21:01Z

This patch adds support for multiple frontend types for each backend algorithm by passing the type and mask through to the backend type init function. Signed-off-by: Herbert Xu

[CRYPTO] api: Add type-safe spawns

2007-02-06T22:21:01Z

This patch allows spawns of specific types (e.g., cipher) to be allocated. Signed-off-by: Herbert Xu

[CRYPTO] lib: table driven multiplications in GF(2^128)

2006-12-07T02:38:55Z

A lot of cypher modes need multiplications in GF(2^128). LRW, ABL, GCM... I use functions from this library in my LRW implementation and I will also use them in my ABL (Arbitrary Block Length, an unencumbered (correct me if I am wrong, wide block cipher mode). Elements of GF(2^128) must be presented as u128 *, it encourages automatic and proper alignment. The library contains support for two different representations of GF(2^128), see the comment in gf128mul.h. There different levels of optimization (memory/speed tradeoff). The code is based on work by Dr Brian Gladman. Notable changes: - deletion of two optimization modes - change from u32 to u64 for faster handling on 64bit machines - support for 'bbe' representation in addition to the, already implemented, 'lle' representation. - move 'inline void' functions from header to 'static void' in the source file - update to use the linux coding style conventions The original can be found at: http://fp.gladman.plus.com/AES/modes.vc8.19-06-06.zip The copyright (and GPL statement) of the original author is preserved.

[CRYPTO] lib: some common 128-bit block operations, nicely centralized

2006-12-07T02:38:55Z

128bit is a common blocksize in linux kernel cryptography, so it helps to centralize some common operations. The code, while mostly trivial, is based on a header file mode_hdr.h in http://fp.gladman.plus.com/AES/modes.vc8.19-06-06.zip The original copyright (and GPL statement) of the original author, Dr Brian Gladman, is preserved.

[CRYPTO] digest: Added user API for new hash type

2006-09-21T01:46:17Z

The existing digest user interface is inadequate for support asynchronous operations. For one it doesn't return a value to indicate success or failure, nor does it take a per-operation descriptor which is essential for the issuing of requests while other requests are still outstanding. This patch is the first in a series of steps to remodel the interface for asynchronous operations. For the ease of transition the new interface will be known as "hash" while the old one will remain as "digest". This patch also changes sg_next to allow chaining. Signed-off-by: Herbert Xu

[CRYPTO] cipher: Added block ciphers for CBC/ECB

2006-09-21T01:44:08Z

This patch adds two block cipher algorithms, CBC and ECB. These are implemented as templates on top of existing single-block cipher algorithms. They invoke the single-block cipher through the new encrypt_one/decrypt_one interface. This also optimises the in-place encryption and decryption to remove the cost of an IV copy each round.
