* crypto: cbc - Export CBC implementationHerbert Xu2016-11-281-127/+2
| | | | | | | This patch moves the core CBC implementation into a header file so that it can be reused by drivers implementing CBC. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: cbc - Convert to skcipherHerbert Xu2016-11-281-104/+138
| | | | | | | This patch converts cbc over to the skcipher interface. It also rearranges the code to allow it to be reused by drivers. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: include crypto- module prefix in templateKees Cook2014-11-261-0/+1
| | | | | | | | | | | | | | | | | | | This adds the module loading prefix "crypto-" to the template lookup as well. For example, attempting to load 'vfat(blowfish)' via AF_ALG now correctly includes the "crypto-" prefix at every level, correctly rejecting "vfat": net-pf-38 algif-hash crypto-vfat(blowfish) crypto-vfat(blowfish)-all crypto-vfat Reported-by: Mathias Krause <minipli@googlemail.com> Signed-off-by: Kees Cook <keescook@chromium.org> Acked-by: Mathias Krause <minipli@googlemail.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

* [CRYPTO] cbc: Require block size to be a power of 2Herbert Xu2008-01-111-8/+10
| | | | | | | | | | | | | | All common block ciphers have a block size that's a power of 2. In fact, all of our block ciphers obey this rule. If we require this then CBC can be optimised to avoid an expensive divide on in-place decryption. I've also changed the saving of the first IV in the in-place decryption case to the last IV because that lets us use walk->iv (which is already aligned) for the xor operation where alignment is required.

* [CRYPTO] cbc: Use crypto_xorHerbert Xu2008-01-111-77/+16
| | | | | | This patch replaces the custom xor in CBC with the generic crypto_xor. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* [CRYPTO] templates: Pass type/mask when creating instancesHerbert Xu2007-05-021-3/+8
| | | | | | | | | | | | | 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 type-safe spawnsHerbert Xu2007-02-071-4/+5
| | | | | | This patch allows spawns of specific types (e.g., cipher) to be allocated. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* [CRYPTO] cipher: Added block ciphers for CBC/ECBHerbert Xu2006-09-211-0/+344
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.
