fnv-text-profile-signature

This project contains 2 items:

1. A 128-bit FNV-1a implementation (which really ought to exist in the java standard lib, but I digress...)
2. An adaptation of the TextProfileSignature class used in solr, adapted from Apache Nutch that does 2 things differently:
   • Uses a LinkedHashMap in place of a regular HashMap, so that the sorting order is predictable
   • Uses an FNV-1a hash for the final result, instead of MD5, so that it can be functionally compatible with in-browser javascript implementations.

This project is built with gradle. It uses gradle's wrapper functionality to guarantee that all users are building with the same version of the build tools without having to jump through hoops to install it. To build, type ./gradlew build; to run the tests type ./gradlew test.

On build, this jar is published to our S3 Maven repository. To use this project as a dependency in a gradle project:

• Add our Maven repo:

   buildscript {
        repositories {
            mavenCentral()
        }

        dependencies {
            classpath 'com.amazonaws:aws-java-sdk:1.11.6'
        }
    }
   import com.amazonaws.auth.DefaultAWSCredentialsProviderChain
   repositories {
        mavenCentral()
        maven {
            url "s3://casetext-ds-code-deploys/maven"
            credentials(AwsCredentials) {
                def defaultCredentials = new DefaultAWSCredentialsProviderChain().getCredentials()
                accessKey defaultCredentials.getAWSAccessKeyId()
                secretKey defaultCredentials.getAWSSecretKey()
            }
        }
   }

• Add compile 'com.casetext:fnv-text-profile-signature:+' to your dependencies block.

and it will be loaded in as any other maven dependency.
