public CompressionHandler getCompressionHandler(CompressionAlgorithm algorithm)
```
    Gets the appropriate CompressionHandler that can perform the required compression using the given compression algorithm.
    
    Parameters:
    
    algorithm - The Compression algorithm.
    
    Returns:
    
    The CompressionHandler.
  - compress
```
public String compress(CompressionAlgorithm compressionAlgorithm,
                       String data)
```
    Convenience method equivalent to Base64url.encode(getCompressionHandler(compressionAlgorithm).compress(data.getBytes(Utils.CHARSET))).
    
    Parameters:
    
    compressionAlgorithm - the compression algorithm to use.
    
    data - the data to compress.
    
    Returns:
    
    the base64url-encoded compressed data.
  - decompress
```
public byte[] decompress(CompressionAlgorithm compressionAlgorithm,
                         String data)
```
    Convenience method equivalent to getCompressionHandler(compressionAlgorithm).decompress(Base64url.decode(data)).
    
    Parameters:
    
    compressionAlgorithm - the compression algorithm to use.
    
    data - the base64url-encoded data to decompress.
    
    Returns:
    
    the decompressed data.
