Class Base32Support

java.lang.Object
net.shibboleth.utilities.java.support.codec.Base32Support
public final class Base32Support
extends Object
Helper class for working with Base32.

This helper class specifically addresses that waste of the Apache Codec encode/decode static methods creating new instances of the Base32 for every operation. It also provides the helper method to produce both chunked and unchunked encoded content as strings.

    • encode

      @Nonnull public static String encode​(@Nonnull byte[] data, boolean chunked) throws EncodingException
      Base32 encodes the given binary data.
      Parameters:
      data - data to encode
      chunked - whether the encoded data should be chunked or not
      Returns:
      the base32 encoded data
      Throws:
      EncodingException - when any Exception is thrown from the underlying encoder, or the output is null.

    • decode

      Decodes (un)chunked Base32 encoded data.
      Parameters:
      data - Base32 encoded data
      Returns:
      the decoded data
      Throws:
      DecodingException - when an Exception is thrown from the underlying decoder, or the output is null.
