This article will explain in detail how to achieve Base64 encryption in Java. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

The following paragraph is about Java Base64 encryption, which should be of some use to everyone.

Import java.io.ByteArrayInputStream

Import java.io.ByteArrayOutputStream

Import java.io.InputStream

Import java.io.OutputStream

Import javax.mail.internet.MimeUtility

Public class Base64 {

Public static byte [] encode (byte [] b) throws Exception {

ByteArrayOutputStream baos = null

OutputStream b64os = null

Try {

Baos = new ByteArrayOutputStream ()

B64os = MimeUtility.encode (baos, "base64")

B64os.write (b)

B64os.close ()

Return baos.toByteArray ()

} catch (Exception e) {

Throw new Exception (e)

} finally {

Try {

If (baos! = null) {

Baos.close ()

Baos = null

}

} catch (Exception e) {

}

Try {

If (b64os! = null) {

B64os.close ()

B64os = null

}

} catch (Exception e) {

}

}

}

Public static byte [] decode (byte [] b) throws Exception {

ByteArrayInputStream bais = null

InputStream b64is = null

Try {

Bais = new ByteArrayInputStream (b)

B64is = MimeUtility.decode (bais, "base64")

Byte [] tmp = new byte [b.length]

Int n = b64is.read (tmp)

Byte [] res = new byte [n]

System.arraycopy (tmp, 0, res, 0, n)

Return res

} catch (Exception e) {

Throw new Exception (e)

} finally {

Try {

If (bais! = null) {

Bais.close ()

Bais = null

}

} catch (Exception e) {

}

Try {

If (b64is! = null) {

B64is.close ()

B64is = null

}

} catch (Exception e) {

}

}

}

}
