2008-04-21[CRYPTO] tcrypt: Change the usage of the test vectorsSebastian Siewior
The test routines (test_{cipher,hash,aead}) are makeing a copy of the test template and are processing the encryption process in place. This patch changes the creation of the copy so it will work even if the source address of the input data isn't an array inside of the template but a pointer.

2008-04-21[CRYPTO] tcrypt: Shrink speed templatesSebastian Siewior
The speed templates as it look always the same. The key size is repeated for each block size and we test always the same block size.

2008-01-11[CRYPTO] tcrypt: Add CCM vectorsJoy Latten
This patch adds 7 test vectors to tcrypt for CCM. The test vectors are from rfc 3610. There are about 10 more test vectors in RFC 3610 and 4 or 5 more in NIST. I can add these as time permits. I also needed to set authsize. CCM has a prerequisite of authsize. Signed-off-by: Joy Latten <latten@austin.ibm.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2008-01-11[CRYPTO] ctr: Refactor into ctr and rfc3686Herbert Xu
As discussed previously, this patch moves the basic CTR functionality into a chainable algorithm called ctr. The IPsec-specific variant of it is now placed on top with the name rfc3686. So ctr(aes) gives a chainable cipher with IV size 16 while the IPsec variant will be called rfc3686(ctr(aes)). This patch also adjusts gcm accordingly.

2008-01-11[CRYPTO] gcm: Fix ICV handlingHerbert Xu
The crypto_aead convention for ICVs is to include it directly in the output. If we decided to change this in future then we would make the ICV (if the algorithm has an explicit one) available in the request itself. For now no algorithm needs this so this patch changes gcm to conform to this convention. It also adjusts the tcrypt aead tests to take this into account.

2008-01-11[CRYPTO] sha256-generic: Extend sha256_generic.c to support SHA-224Jonathan Lynch
Resubmitting this patch which extends sha256_generic.c to support SHA-224 as described in FIPS 180-2 and RFC 3874. HMAC-SHA-224 as described in RFC4231 is then supported through the hmac interface. Patch includes test vectors for SHA-224 and HMAC-SHA-224. SHA-224 chould be chosen as a hash algorithm when 112 bits of security strength is required. Patch generated against the 2.6.24-rc1 kernel and tested against 2.6.24-rc1-git14 which includes fix for scatter gather implementation for HMAC.

2008-01-11[CRYPTO] ctr: Add countersizeJoy Latten
This patch adds countersize to CTR mode. The template is now ctr(algo,noncesize,ivsize,countersize). For example, ctr(aes,4,8,4) indicates the counterblock will be composed of a salt/nonce that is 4 bytes, an iv that is 8 bytes and the counter is 4 bytes. When noncesize + ivsize < blocksize, CTR initializes the last block - ivsize - noncesize portion of the block to zero. Otherwise the counter block is composed of the IV (and nonce if necessary). If noncesize + ivsize == blocksize, then this indicates that user is passing in entire counterblock. Thus countersize indicates the amount of bytes in counterblock to use as the counter for incrementing. CTR will increment counter portion by 1, and begin encryption with that value. Note that CTR assumes the counter portion of the block that will be incremented is stored in big endian.

2008-01-11[CRYPTO] ctr: Add CTR (Counter) block cipher modeJoy Latten
This patch implements CTR mode for IPsec. It is based off of RFC 3686. Please note: 1. CTR turns a block cipher into a stream cipher. Encryption is done in blocks, however the last block may be a partial block. A "counter block" is encrypted, creating a keystream that is xor'ed with the plaintext. The counter portion of the counter block is incremented after each block of plaintext is encrypted. Decryption is performed in same manner. 2. The CTR counterblock is composed of, nonce + IV + counter The size of the counterblock is equivalent to the blocksize of the cipher. sizeof(nonce) + sizeof(IV) + sizeof(counter) = blocksize The CTR template requires the name of the cipher algorithm, the sizeof the nonce, and the sizeof the iv. ctr(cipher,sizeof_nonce,sizeof_iv) So for example, ctr(aes,4,8) specifies the counterblock will be composed of 4 bytes from a nonce, 8 bytes from the iv, and 4 bytes for counter since aes has a blocksize of 16 bytes. 3. The counter portion of the counter block is stored in big endian for conformance to rfc 3686. Signed-off-by: Joy Latten <latten@austin.ibm.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

2007-10-10[CRYPTO] xts: XTS blockcipher mode implementation without partial blocksRik Snel
XTS currently considered to be the successor of the LRW mode by the IEEE1619 workgroup. LRW was discarded, because it was not secure if the encyption key itself is encrypted with LRW. XTS does not have this problem. The implementation is pretty straightforward, a new function was added to gf128mul to handle GF(128) elements in ble format. Four testvectors from the specification http://grouper.ieee.org/groups/1619/email/pdf00086.pdf were added, and they verify on my system.

2006-09-21[CRYPTO] api: Get rid of flags argument to setkeyHerbert Xu
Now that the tfm is passed directly to setkey instead of the ctx, we no longer need to pass the &tfm->crt_flags pointer. This patch also gets rid of a few unnecessary checks on the key length for ciphers as the cipher layer guarantees that the key length is within the bounds specified by the algorithm. Rather than testing dia_setkey every time, this patch does it only once during crypto_alloc_tfm. The redundant check from crypto_digest_setkey is also removed. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2006-09-21[CRYPTO] crc32c: Fix unconventional setkey usageHerbert Xu
The convention for setkey is that once it is set it should not change, in particular, init must not wipe out the key set by it. In fact, init should always be used after setkey before any digestion is performed. The only user of crc32c that sets the key is tcrypt. This patch adds the necessary init calls there.
