Description

Library to represent binary data as ASCII characters. Base64-encoded data takes about 33% more space than the original data. Allows encoding and decoding. Supports English and Russian strings for decoding/encoding, other languages can simply be added by editing base64_binarydatamap.xml

Requirements

any lib that can do XSLT 1.0 transformation such as libxml, xsltproc, xerces, saxon, Microsoft msxml etc

Example

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet 
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    xmlns:b64="https://github.com/ilyakharlamov/xslt_base64"
    version="1.0">
    <xsl:output method="text"/>
    <xsl:include href="base64.xsl"/>
    <xsl:template match="/">
        <xsl:text>encoded Man is </xsl:text>
        <xsl:call-template name="b64:encode">
            <xsl:with-param name="asciiString" select="'Man'"/>
        </xsl:call-template>
	<xsl:text>&#x0A;encoded unicode Человек is </xsl:text>
        <xsl:call-template name="b64:encode">
            <xsl:with-param name="asciiString" select="'Человек'"/>
        </xsl:call-template>
        <xsl:text>&#x0A;encoded 1 with padding is </xsl:text>
        <xsl:call-template name="b64:encode">
            <xsl:with-param name="asciiString" select="'1'"/>
        </xsl:call-template>
        <xsl:text>&#x0A;encoded 1 without padding is </xsl:text>
        <xsl:call-template name="b64:encode">
            <xsl:with-param name="asciiString" select="'1'"/>
            <xsl:with-param name="padding" select="false()"/>
        </xsl:call-template>
        <xsl:text>&#x0A;decoded MQ== is </xsl:text>
        <xsl:call-template name="b64:decode">
             <xsl:with-param name="base64String" select="'MQ=='"/>
        </xsl:call-template>
    </xsl:template>
</xsl:stylesheet>

Output:

encoded Man is TWFu
encoded unicode Человек is 0KfQtdC70L7QstC10Lo=
encoded 1 with padding is MQ==
encoded 1 without padding is MQ
decoded MQ== is 1

Also supports 'url safe' and 'no padding' syntax via params to b64:encode template
