Base62 license

A Base62 Encoder/Decoder for Java

Getting Started

For Maven-based projects, add the following to your pom.xml file. This dependency is available from the Maven Central repository.

<dependency>
    <groupId>io.seruco.encoding</groupId>
    <artifactId>base62</artifactId>
    <version>0.1.3</version>
</dependency>

Usage

Base62 base62 = Base62.createInstance();

Encoding

final byte[] encoded = base62.encode("Hello World".getBytes());

new String(encoded); // is "73XpUgyMwkGr29M"

Decoding

final byte[] decoded = base62.decode("73XpUgyMwkGr29M".getBytes());

new String(decoded); // is "Hello World"

Character Sets

This library supports two character sets: GMP-style or inverted. The difference between these two is whether the upper case letters come first, 0-9A-Za-z (GMP), or last, 0-9a-zA-Z (inverted).

By default, we prefer the GMP-style character set. If you want to use the inverted character set, simply do this:

Base62 base62 = Base62.createInstanceWithInvertedCharacterSet();
