<p>Use the <b>base64Encode</b> function to <glossary tag="encode">encode</glossary> <glossary tag="binary data">binary data</glossary> for transmission over communication channels that don't accept raw <glossary tag="binary data">binary data</glossary>.</p><p></p><p><b>Parameters:</b></p><p>The <i>data</i> is a string of <glossary tag="binary data">binary data</glossary> of any length.</p><p></p><p><b>Value:</b></p><p>The <b>base64Encode</b> function <glossary tag="return">returns</glossary> a text <keyword tag="string">string</keyword> representing the binary <i>data</i>.</p><p></p><p><b>Comments:</b></p><p>The <b>base64Encode</b> function is the <keyword tag="inverse">inverse</keyword> of the <function tag="base64Decode">base64Decode</function> <control_st tag="function">function</control_st>. The <glossary tag="encode">encoded</glossary> result is generally about a third larger than the original data.</p><p>The encoded string returned by <b>base64Encode</b> <control_st tag="function">function</control_st> can include uppercase and lowercase letters, digits, +, /, and =, but no other characters. Base 64-encoded data is wrapped at 72 characters, so each <keyword tag="line">line</keyword> of the <glossary tag="encode">encoded</glossary> data is 72 <keyword tag="characters">characters</keyword> or (for the last or only line) fewer.</p><p>The base 64 encoding scheme is often used to encode binary data for MIME mail and HTTP transfers.</p><p>For technical information about base 64 encoding, see section 6.8 of RFC 2045 at &lt;<u>http://www.ietf.org/rfc/rfc2045.txt</u>&gt;.</p>
