Updated the benchmark data to cover all the implemented hashes. check-in: bd6f8082de user: aku tags: trunk
2021-02-24
21:22
Prettified the hash definitions consumed by the glue. check-in: 6d76a4f927 user: aku tags: trunk
20:27
Completed the test suite. Now covers all implemented hashes. Replaced the multitude of separate files for expected digests and references with aggregations in .tsv format (csv using TAB) and updated the test code to match. Fixes: - Worked around bad TTH digest size in tth.h - https://github.com/rhash/RHash/issues/143 - Fixed EDON-R/384 init code, again wrong digest size - https://github.com/rhash/RHash/issues/144 Added more references. check-in: 70490bd09c user: aku tags: trunk
10:08
Extended set of test vectors with examples found for the hash functions outside of md*, sha*. Plus results for md*, sha*. Renamed/labeled some of the older vectors to reduce length of the file names in the results. check-in: f274e91267 user: aku tags: trunk
07:56
Dropped the input files for the test vectors. These are now all in the test utilities. See commit [d02c310d65]. Added the variant sha2/3 hashes to the set of tested functions. In the utility functions. Added the necessary result files. Reworked hash.test to use the data from the utilities. Ditto for references. Not for list, to prevent it from failing. Switching is not possible until the hash list in the utilities covers all the supported functions. check-in: 336b86f314 user: aku tags: trunk
07:48
Fixed the definitions of sha2 224/384. They effectively used the base sha256/sha512 definitions before. Placed hash information and test vectors into the test utilities. Updated `size.test` to use this. `hash.test` to come. check-in: d02c310d65 user: aku tags: trunk
07:43
Added all missing hashes to the benchmarks. check-in: 309e0da765 user: aku tags: trunk
07:40
Added documentation. Generated embedded form. Added github specific files for future mirror. check-in: 698f480a40 user: aku tags: trunk
2021-02-21
22:11
Added the majority of the hashes provided by RHash. Changed the names of the basic `sha2` and `sha3` commands. These are now `sha2/256` and `sha3/256`. Updated testsuite to match. check-in: 67c4a6cdf6 user: aku tags: trunk

Updated performance notes. See [6d818bf1f32ac653] for comparison. |Hash|Bytes |Micros |MB/Sec|MiB/Sec|Micros/Byte|Gain |R/Gain| |--- |---: |---: |---: |---: |---: |---: |---: | |md4 | 524288| 686.469|763.75| 728.37|0.0013 |11.967| 1.564| |md5 | 1048576| 2146.825|488.43| 465.80|0.0020 | 7.653| 2.565| |sha1|67108864| 352426.623|190.42| 181.60|0.0053 | 2.984| 1.094| |sha2| 262144| 1505.720|174.10| 166.03|0.0057 | 2.728| 2.728| |sha3|67108864|1051598.331| 63.82| 60.86|0.0157 | 1.000| 1.000| With the exception of SHA-1 all hashes got a performance boost. The oldest of the hashes, MD-4, got the largest boost, jumping it to the top spot, overtaking both MD-5 and SHA-1.The modern SHA-3 is still trailing all the others, although not as much anymore as before the switch to RHash. Overall I call that a success. check-in: 2edd03f7cd user: aku tags: trunk
16:33
Removed the old and now unused implementations for the hashes switched over to RHash. check-in: 432df679ea user: aku tags: trunk
16:32
Switched all hashes but SHA-1 to the new implementations prtovided by RHash. Tweaked the old SHA-1 sources to avoid clash with the rhash header (Both had the same name, `sha1.h`). Updated testsuite to match the changed references. Headers and sources are now coming out of the hash definitions, instead of standing separate. This simplifies the higher level code, as it will not require further changes when hash functions are added, removed, or modified. check-in: a625126a1a user: aku tags: trunk
16:26
Reworked the post processors for the benachmark data. Adapted to the changes in the file prefix (`B` -> `bench`). Further better handling of per-hash max speed data. check-in: 8dc92713cf user: aku tags: trunk
16:23
Brought in the https://github.com/rhash/RHash sources for lots of hash functions. This will replace much of the old sources. The preliminary benchmarking indicates performance boost to most of the functions currently in the package. SHA-1 is an exception, for this the old sources are faster. RHash will also provide access to a number of other hash functions of interest. check-in: 28da222f74 user: aku tags: trunk

Benchmarks added, and results of a first run. Proven general O(n) behaviour for 2^n scaled inputs, 5 to 26, i.e. 64 bytes to 64 MiB. Relative performance of the various hashes. Note, benchmarking was done only for the `channel` method of all hashes. The other two methods (`string`, and `path`) are slightly faster and slower, respectively, due to their different actions around the hash core. SHA3's implementation stands out as the worst here, about 7 times slower than SHA2, the second-worst. 14 times slower than the fastest implementation, which was for MD5. And the relative gains show a very sharp cliff for it. |Hash|Bytes |Microseconds |MB/sec|MiB/sec|Microseconds/Byte|Gain |R/Gain| |--- |--- |---: |---: |---: |---: |---: |---: | |md5 | 262144| 1224.644|214.06| 204.14| 0.0047|14.147| 1.202| |sha1|33554432| 188385.998|178.12| 169.87| 0.0056|11.772| 1.243| |md4 | 262144| 1829.052|143.32| 136.68| 0.0070| 9.472| 1.341| |sha2| 262144| 2452.493|106.89| 101.94| 0.0094| 7.064| 7.064| |sha3| 262144| 17323.348| 15.13| 14.43| 0.0661| 1.000| 1.000| check-in: 6d818bf1f3 user: aku tags: trunk
