Modifier and Type	Method and Description
public int	Returns: compression algorithm ID as specified by RFC8879. algorithmId() Return the ID for the compression algorithm provided for by a given implementation.
public byte[]	Returns: the compressed form of the certificate compress(SSLEngine the `SSLEngine` engine, byte[] the uncompressed certificate uncompressedCertificate) Compress the given input with the specified algorithm and return the compressed bytes.
public byte[]	Returns: the decompressed form of the certificate decompress(SSLEngine the `SSLEngine` engine, int the expected length of the decompressed certificate that will be returned. uncompressedLen, byte[] the compressed form of the certificate compressedCertificate) Decompress the given input with the specified algorithm and return the decompressed bytes.

public byte[] compress(SSLEngine engine, byte[] uncompressedCertificate) throws Exception Compress the given input with the specified algorithm and return the compressed bytes. Parameters engine:SSLEngine the `SSLEngine` uncompressedCertificate:byte[] the uncompressed certificate Returns:byte[] the compressed form of the certificate Exceptions Exception: thrown if an error occurs while compressing

public byte[] compress(SSLEngine engine, byte[] uncompressedCertificate) throws Exception

Compress the given input with the specified algorithm and return the compressed bytes.

decompress	back to summary
public byte[] decompress(SSLEngine engine, int uncompressedLen, byte[] compressedCertificate) throws Exception Decompress the given input with the specified algorithm and return the decompressed bytes. Implementation Security Considerations Implementations SHOULD bound the memory usage when decompressing the CompressedCertificate message. Implementations MUST limit the size of the resulting decompressed chain to the specified `uncompressedLen`, and they MUST abort the connection (throw an exception) if the size of the output of the decompression function exceeds that limit. Parameters engine:SSLEngine the `SSLEngine` uncompressedLen:int the expected length of the decompressed certificate that will be returned. compressedCertificate:byte[] the compressed form of the certificate Returns:byte[] the decompressed form of the certificate Exceptions Exception: thrown if an error occurs while decompressing or output size exceeds `uncompressedLen`

public byte[] decompress(SSLEngine engine, int uncompressedLen, byte[] compressedCertificate) throws Exception

Decompress the given input with the specified algorithm and return the decompressed bytes.

Implementation Security Considerations

Implementations SHOULD bound the memory usage when decompressing the CompressedCertificate message.

Implementations MUST limit the size of the resulting decompressed chain to the specified uncompressedLen, and they MUST abort the connection (throw an exception) if the size of the output of the decompression function exceeds that limit.
