2008-04-21[CRYPTO] cts: Add CTS mode required for Kerberos AES supportKevin Coffman
Implement CTS wrapper for CBC mode required for support of AES encryption support for Kerberos (rfc3962). Signed-off-by: Kevin Coffman <kwc@citi.umich.edu> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2008-04-21[CRYPTO] tcrypt: Change the XTEA test vectorsSebastian Siewior
The third test vector of ECB-XTEA-ENC fails for me all other are fine. I could not find a RFC or something else where they are defined. The test vector has not been modified since git started recording histrory. The implementation is very close (not to say equal) to what is available as Public Domain (they recommend 64 rounds and the in kernel uses 32). Therefore I belive that there is typo somewhere and tcrypt reported always *fail* instead of *okey*. This patch replaces input + result of the third test vector with result + input from the third decryption vector. The key is the same, the other three test vectors are also the reverse.

2008-04-21[CRYPTO] tcrypt: Shrink the tcrypt moduleSebastian Siewior
Currently the tcrypt module is about 2 MiB on x86-32. The main reason for the huge size is the data segment which contains all the test vectors for each algorithm. The test vectors are staticly allocated in an array and the size of the array has been drastically increased by the merge of the Salsa20 test vectors. With a hint from Benedigt Spranger I found a way how I could convert those fixed-length arrays to strings which are flexible in size. VIM and regex were also very helpfull :) So, I am talking about a shrinking of ~97% on x86-32: text data bss dec hex filename 18309 2039708 20 2058037 1f6735 tcrypt-b4.ko 45628 23516 80 69224 10e68 tcrypt.ko Signed-off-by: Sebastian Siewior <sebastian@breakpoint.cc> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
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. The addition of one inner loop makes it possible to get rid of the struct and it is possible to use a tiny u8 array :) Signed-off-by: Sebastian Siewior <sebastian@breakpoint.cc> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2008-04-21[CRYPTO] tcrypt: Group common speed templatesSebastian Siewior
Some crypto ciphers which are impleneted support similar key sizes (16,24 & 32 byte). They can be grouped together and use a common templatte instead of their own which contains the same data.

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] 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] tcrypt: AES CBC test vectors from NIST SP800-38AJan Glauber

2008-01-11[CRYPTO] tcrypt: AES CTR large test vectorTan Swee Heng
This patch adds a large AES CTR mode test vector. The test vector is 4100 bytes in size. It was generated using a C++ program that called Crypto++. Note that this patch increases considerably the size of "struct cipher_testvec" and hence the size of tcrypt.ko.

2008-01-11[CRYPTO] salsa20: Salsa20 stream cipherTan Swee Heng
This patch implements the Salsa20 stream cipher using the blkcipher interface. The core cipher code comes from Daniel Bernstein's submission to eSTREAM: http://www.ecrypt.eu.org/stream/svn/viewcvs.cgi/ecrypt/trunk/submissions/salsa20/full/ref/ The test vectors comes from: http://www.ecrypt.eu.org/stream/svn/viewcvs.cgi/ecrypt/trunk/submissions/salsa20/full/ It has been tested successfully with "modprobe tcrypt mode=34" on an UML instance.

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 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.

2006-06-26[CRYPTO] tcrypt: Speed benchmark support for digest algorithmsMichal Ludvig
This patch adds speed tests (benchmarks) for digest algorithms. Tests are run with different buffer sizes (16 bytes, ... 8 kBytes) and with each buffer multiple tests are run with different update() sizes (e.g. hash 64 bytes buffer in four 16 byte updates). There is no correctness checking of the result and all tests and algorithms use the same input buffer.

From: Reyk Floeter <reyk@vantronix.net> I recently had the requirement to do some benchmarking on cryptoapi, and I found reyk's very useful performance test patch [1]. However, I could not find any discussion on why that extension (or something providing a similar feature but different implementation) was not merged into mainline. If there was such a discussion, can someone please point me to the archive[s]? I've now merged the old patch into 2.6.12-rc1, the result can be found attached to this email.

2005-04-16Linux-2.6.12-rc2Linus Torvalds
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
