Base64 is a freeware way of encoding 8-bit characters usingonly ASCII printable characters similar to UUENCODE.UUENCODE embeds a filename where BASE64 does not. You willsee BASE64 used in encoding digital certificates inencoding user:password string in an Authorization: headerfor HTTP. The spec is described in RFC 2045.Dont confuse Base64 with x-www-form-urlencoded whichis handled by java.net.URLEncoder.encodedecode orBase64u.Base64 armouring uses only the characters A-Z a-z 0-9 +.This makes it suitable for encoding binary data as SQLstrings that will work no matter what the encoding.Unfortunately + and all have special meaning in URLs.Base64u gets around this problem. It is a variant on Base64that uses - _ and * in preference to + and so that itcan be used in URLEncoded contexts with or withoutURLEncoding.Use base64 like this: Base64 armouringimport com.mindprod.base64.Base64... sample byte array to encodebyte toSend (byte)0xfc (byte)0x0f (byte)0xc0 create encoder objectBase64 base64 new Base64()base64.setLineLength( 72 ) default encoding a byteString send base64.encoder( toSend ) decoding a bytebyte reconstituted base64.decoder( sent )use Base64u the same way: Base64u armouringimport com.mindprod.base64.Base64u... sample byte array to encodebyte toSend (byte)0xfc (byte)0x0f (byte)0xc0 create encoder objectBase64u base64u new Base64u()base64u.setLineLength( 72 ) default encoding a byteString send base64u.encoder( toSend ) decoding a bytebyte reconstituted base64u.decoder( sent )For an example that starts and ends with a String seeExample.javato run:java.exe com.mindprod.base64.Example
