Step 1. Add the JitPack repository to your build file

Add it in your root settings.gradle at the end of repositories:

	dependencyResolutionManagement {
		repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
		repositories {
			mavenCentral()
			maven { url 'https://jitpack.io' }
		}
	}

Add it in your settings.gradle.kts at the end of repositories:

	dependencyResolutionManagement {
		repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
		repositories {
			mavenCentral()
			maven { url = uri("https://jitpack.io") }
		}
	}

Add to pom.xml

	<repositories>
		<repository>
		    <id>jitpack.io</id>
		    <url>https://jitpack.io</url>
		</repository>
	</repositories>

Add it in your build.sbt at the end of resolvers:

 
    resolvers += "jitpack" at "https://jitpack.io"

Add it in your project.clj at the end of repositories:

 
    :repositories [["jitpack" "https://jitpack.io"]]

Step 2. Add the dependency

	dependencies {
		implementation 'com.github.danieltwagner:iso7064:'
	}

	dependencies {
		implementation("com.github.danieltwagner:iso7064:")
	}

	<dependency>
	    <groupId>com.github.danieltwagner</groupId>
	    <artifactId>iso7064</artifactId>
	    <version></version>
	</dependency>


                            
    libraryDependencies += "com.github.danieltwagner" % "iso7064" % ""


                            
    :dependencies [[com.github.danieltwagner/iso7064 ""]]

Readme

iso7064

A simple Java library that calculates ISO 7064 check characters.

The algorithms currently included are all pure systems:

ISO/IEC 7064, MOD 11-2 for numeric strings with one check digit or the supplementary check character "X"
ISO/IEC 7064, MOD 37-2 for alphanumeric strings with one check digit or letter or the supplementary check character "*"
ISO/IEC 7064, MOD 97-10 for numeric strings with two check digits
ISO/IEC 7064, MOD 661-26 for alphabetic strings with two check letters
ISO/IEC 7064, MOD 1271-36 for alphanumeric strings with two check digits or letters

This is a partial implementation of the ISO standard. Hybrid systems (which always produce a single check character within the character set of the string that is being protected) are not implemented at this time. The missing systems are:

ISO/IEC 7064, MOD 11,10 for numeric strings with one check digit
ISO/IEC 7064, MOD 27,26 for alphabetic strings with one check letter
ISO/IEC 7064, MOD 37,36 for alphanumeric strings with one check digit or letter

Mod11_2 numericCheck = new Mod11_2();

String protected = numericCheck.compute("123456");
boolean result = numericCheck.verify("123456X");
