Base64 (Wicket Parent 8.15.0-SNAPSHOT API)

- org.apache.wicket.util.crypt.Base64

Deprecated.
Use Base64 instead.
```
@Deprecated
public class Base64
extends Object
```
Provides Base64 encoding and decoding with URL and filename safe alphabet as defined by RFC 3548, section 4.
This Base64 encoder is modified to meet URL requirements. The changes are: '+' => '*', '/' => '-', and no padding.
This class is taken from the Apache commons-codec, and adjusted to fit the Wicket framework's needs, especially external dependencies have been removed.

This class implements section 4. Base 64 Encoding with URL and Filename Safe Alphabet from RFC 3548 The Base16, Base32, and Base64 Data Encodings by Simon Josefsson.

1.2

  - Base64
```
public Base64()
```
    Deprecated.
    
    Creates a Base64 codec used for decoding (all modes) and encoding in URL-unsafe mode.
    When encoding the line length is 76, the line separator is CRLF, and the encoding table is STANDARD_ENCODE_TABLE.
    
    When decoding all variants are supported.
  - Base64
```
public Base64(boolean urlSafe)
```
    Deprecated.
    
    Creates a Base64 codec used for decoding (all modes) and encoding in the given URL-safe mode.
    When encoding the line length is 76, the line separator is CRLF, and the encoding table is STANDARD_ENCODE_TABLE.
    
    When decoding all variants are supported.
    
    Parameters:
    
    urlSafe - if true, URL-safe encoding is used. In most cases this should be set to false.
    
    Since:
    
    1.4
  - Base64
```
public Base64(int lineLength)
```
    Deprecated.
    
    Creates a Base64 codec used for decoding (all modes) and encoding in URL-unsafe mode.
    When encoding the line length is given in the constructor, the line separator is CRLF, and the encoding table is STANDARD_ENCODE_TABLE.
    
    Line lengths that aren't multiples of 4 will still essentially end up being multiples of 4 in the encoded data.
    
    When decoding all variants are supported.
    
    Parameters:
    
    lineLength - Each line of encoded data will be at most of the given length (rounded down to nearest multiple of 4). If lineLength <= 0, then the output will not be divided into lines (chunks). Ignored when decoding.
    
    Since:
    
    1.4
  - Base64
```
public Base64(int lineLength,
              byte[] lineSeparator)
```
    Deprecated.
    
    Creates a Base64 codec used for decoding (all modes) and encoding in URL-unsafe mode.
    When encoding the line length and line separator are given in the constructor, and the encoding table is STANDARD_ENCODE_TABLE.
    
    Line lengths that aren't multiples of 4 will still essentially end up being multiples of 4 in the encoded data.
    
    When decoding all variants are supported.
    
    Parameters:
    
    lineLength - Each line of encoded data will be at most of the given length (rounded down to nearest multiple of 4). If lineLength <= 0, then the output will not be divided into lines (chunks). Ignored when decoding.
    
    lineSeparator - Each line of encoded data will end with this sequence of bytes.
    
    Throws:
    
    IllegalArgumentException - Thrown when the provided lineSeparator included some base64 characters.

public Base64(int lineLength,
              byte[] lineSeparator,
              boolean urlSafe)
```
    Deprecated.
    
    Creates a Base64 codec used for decoding (all modes) and encoding in URL-unsafe mode.
    When encoding the line length and line separator are given in the constructor, and the encoding table is STANDARD_ENCODE_TABLE.
    
    Line lengths that aren't multiples of 4 will still essentially end up being multiples of 4 in the encoded data.
    
    When decoding all variants are supported.
    
    Parameters:
    
    lineLength - Each line of encoded data will be at most of the given length (rounded down to nearest multiple of 4). If lineLength <= 0, then the output will not be divided into lines (chunks). Ignored when decoding.
    
    lineSeparator - Each line of encoded data will end with this sequence of bytes.
    
    urlSafe - Instead of emitting '+' and '/' we emit '-' and '_' respectively. urlSafe is only applied to encode operations. Decoding seamlessly handles both modes.
    
    Throws:
    
    IllegalArgumentException - The provided lineSeparator included some base64 characters. That's not going to work!
