Description: declaration: package: org.apache.tomcat.jni, class: SSLSocket

# Class SSLSocket

java.lang.Object
org.apache.tomcat.jni.SSLSocket

@Deprecated public class SSLSocket extends Object
Deprecated.
The scope of the APR/Native Library will be reduced in Tomcat 9.1.x / Tomcat Native 2.x and has been reduced in Tomcat 10.1.x / Tomcat Native 2.x onwards to only include those components required to provide OpenSSL integration with the NIO and NIO2 connectors.

- ## Method Details

  - ### attach

    public static int attach(long ctx, long sock) throws Exception
    Deprecated.
    Attach APR socket on an SSL connection.
    Parameters:
      `ctx` - SSLContext to use.
      `sock` - APR Socket that already did physical connect or accept.
    Returns:
      APR_STATUS code.
    Throws:
      `Exception` - An error occurred

  - ### handshake

    public static int handshake(long thesocket)
    Deprecated.
    Do an SSL handshake.
    Parameters:
      `thesocket` - The socket to use
    Returns:
      the handshake status

  - ### renegotiate

    public static int renegotiate(long thesocket)
    Deprecated.
    Do an SSL renegotiation. SSL supports per-directory re-configuration of SSL parameters. This is implemented by performing an SSL renegotiation of the re-configured parameters after the request is read, but before the response is sent. In more detail: the renegotiation happens after the request line and MIME headers were read, but _before_ the attached request body is read. The reason simply is that in the HTTP protocol usually there is no acknowledgment step between the headers and the body (there is the 100-continue feature and the chunking facility only), so Apache has no API hook for this step.
    Parameters:
      `thesocket` - The socket to use
    Returns:
      the operation status

  - ### setVerify

    public static void setVerify(long sock, int level, int depth)
    Deprecated.
    Set Type of Client Certificate verification and Maximum depth of CA Certificates in Client Certificate verification.
    This is used to change the verification level for a connection prior to starting a re-negotiation.
    The following levels are available for level:

        SSL_CVERIFY_NONE           - No client Certificate is required at all
        SSL_CVERIFY_OPTIONAL       - The client may present a valid Certificate
        SSL_CVERIFY_REQUIRE        - The client has to present a valid
                                     Certificate
        SSL_CVERIFY_OPTIONAL_NO_CA - The client may present a valid Certificate
                                     but it need not to be (successfully)
                                     verifiable

    Parameters:
      `sock` - The socket to change.
      `level` - Type of Client Certificate verification.
      `depth` - Maximum number of certificates to permit in chain from client to trusted CA. Use a value of 0 or less to leave the current value unchanged

  - ### getInfoB

    public static byte[] getInfoB(long sock, int id) throws Exception
    Deprecated.
    Return SSL Info parameter as byte array.
    Parameters:
      `sock` - The socket to read the data from.
      `id` - Parameter id.
    Returns:
      Byte array containing info id value.
    Throws:
      `Exception` - An error occurred

  - ### getInfoS

    public static String getInfoS(long sock, int id) throws Exception
    Deprecated.
    Return SSL Info parameter as String.
    Parameters:
      `sock` - The socket to read the data from.
      `id` - Parameter id.
    Returns:
      String containing info id value.
    Throws:
      `Exception` - An error occurred

  - ### getInfoI

    public static int getInfoI(long sock, int id) throws Exception
    Deprecated.
    Return SSL Info parameter as integer.
    Parameters:
      `sock` - The socket to read the data from.
      `id` - Parameter id.
    Returns:
      Integer containing info id value or -1 on error.
    Throws:
      `Exception` - An error occurred

  - ### getALPN

    public static int getALPN(long sock, byte[] negotiatedProtocol)
    Deprecated.
    Obtain the name of the protocol negotiated via ALPN. Only valid after the TLS handshake has completed.
    Parameters:
      `sock` - Socket
      `negotiatedProtocol` - Byte array in which to store agreed protocol
    Returns:
      Length of agreed protocol. Zero means no protocol agreed.
