Saphir Hash is a Java library for calculating cryptographic message digests.
The library is derived from the sphlib 3.0 code that can be found here:
[http://www.saphir2.com/sphlib/](http://www.saphir2.com/sphlib/ "sphlib 3.0 project page")
The repackaged, mavenized and JCA-enabled version 3.0.3 and later can be found here:
[https://github.com/sfuhrm/saphir-hash](https://github.com/sfuhrm/saphir-hash "github saphir-hash project page")
Compared to the standard SUN message digest algorithm this library
contains many experimental hash algorithms.

Documentation
----------------
You can view the api docs online at [javadoc.io](https://javadoc.io/doc/de.sfuhrm/saphir-hash-core).
The documentation can be generated with the command
```bash
mvn javadoc:aggregate
```
Building
----------------
The library is built with Apache Maven. You can build it by
doing
```bash
mvn clean package
```
in the top library folder.
Authors
----------------
The original library was written by the "Projet RNRT SAPHIR",
which is a research project sponsored by the French government;
project members are public and private organizations:
* Cryptolog
* ANSSI
* École Normale Superieure
* France Telecom
* Gemalto
Projet RNRT SAPHIR was continued into Projet RNRT SAPHIR2, with four new additional members:
* Cassidian
* Morpho
* INRIA
* UVSQ
We use the "Projet RNRT SAPHIR" expression to designate both SAPHIR and SAPHIR2.
All the actual code has been written by:
Thomas Pornin <thomas.pornin at cryptolog.com>
The additions were written by:
Stephan Fuhrmann <s at sfuhrm.de>
List of changes
----------------
The following is a rough list of changes and additions done by me,
Stephan Fuhrmann:
* Moved project structure to modern maven build with subprojects.
* Moved tests to JUnit tests.
* Created JCA adapter to the digest algorithms.
* Created speed benchmark code to compare against SUN and BouncyCastle implementations.
Maven dependencies
----------------
You can use the code using the Maven repository.
The core classes without JCA support is in this dependency (version may change):
```xml
de.sfuhrm
saphir-hash-core
3.0.10
```
The JCA provider is contained in this dependency (version may change):
```xml
de.sfuhrm
saphir-hash-jca
3.0.10
```
Example usage
----------------
The following short example directly instantiates
fr.cryptohash.JCAProvider and calculates a digest over
the String "test" in the platforms default character encoding:
```java
import fr.cryptohash.JCAProvider;
...
MessageDigest mdSH = MessageDigest.getInstance("MD5", new JCAProvider());
mdSH.update("test".getBytes());
byte mdSHDigest[] = mdSH.digest();
```
Performance discussion
----------------
The following image shows the performance of different algorithm implementations
for a data size of 1M. The numbers are in nanoseconds:
The implementations are:
* JDK 1.8.0_121
* Bouncy Castle 1.46
* Saphir Hash JCA 3.0.3

----------------
