    • decode

      public static byte[] decode(String str, int flags)
      Decode the Base64-encoded data in input and return the data in a new byte array.

      The padding '=' characters at the end are considered optional, but if any are present, there must be the correct number of them.

      参数:
      str - the input String to decode, which is converted to bytes using the default charset
      flags - controls certain features of the decoded output. Pass DEFAULT to decode standard Base64.
      抛出:
      IllegalArgumentException - if the input contains incorrect padding

    • decode

      public static byte[] decode(byte[] input, int flags)
      Decode the Base64-encoded data in input and return the data in a new byte array.

      The padding '=' characters at the end are considered optional, but if any are present, there must be the correct number of them.

      参数:
      input - the input array to decode
      flags - controls certain features of the decoded output. Pass DEFAULT to decode standard Base64.
      抛出:
      IllegalArgumentException - if the input contains incorrect padding

    • encode

      public static byte[] encode(String str, int flags)
      Base64-encode the given data and return a newly allocated byte[] with the result.
      参数:
      str - the string to encode
      flags - controls certain features of the encoded output. Passing DEFAULT results in output that adheres to RFC 2045.

    • encode

      public static byte[] encode(byte[] input, int flags)
      Base64-encode the given data and return a newly allocated byte[] with the result.
      参数:
      input - the data to encode
      flags - controls certain features of the encoded output. Passing DEFAULT results in output that adheres to RFC 2045.
