Field Detail

USE_TASKS

public static final OpenSslContextOption<java.lang.Boolean> USE_TASKS

If enabled heavy-operations may be offloaded from the EventLoop if possible.

TLS_FALSE_START

public static final OpenSslContextOption<java.lang.Boolean> TLS_FALSE_START

If enabled TLS false start will be enabled if supported. When TLS false start is enabled the flow of SslHandshakeCompletionEvents may be different compared when, not enabled. This is currently only supported when BoringSSL and ALPN is used.

PRIVATE_KEY_METHOD

public static final OpenSslContextOption<OpenSslPrivateKeyMethod> PRIVATE_KEY_METHOD

Set the OpenSslPrivateKeyMethod to use. This allows to offload private-key operations if needed. This is currently only supported when BoringSSL is used.

ASYNC_PRIVATE_KEY_METHOD

public static final OpenSslContextOption<OpenSslAsyncPrivateKeyMethod> ASYNC_PRIVATE_KEY_METHOD

Set the OpenSslAsyncPrivateKeyMethod to use. This allows to offload private-key operations if needed. This is currently only supported when BoringSSL is used.

CERTIFICATE_COMPRESSION_ALGORITHMS

public static final OpenSslContextOption<OpenSslCertificateCompressionConfig> CERTIFICATE_COMPRESSION_ALGORITHMS

Set the OpenSslCertificateCompressionConfig to use. This allows for the configuration of certificate compression algorithms which should be used, the priority of those algorithms and the directions in which they should be used. This is currently only supported when BoringSSL is used.

MAX_CERTIFICATE_LIST_BYTES

public static final OpenSslContextOption<java.lang.Integer> MAX_CERTIFICATE_LIST_BYTES

Set the maximum number of bytes that is allowed during the handshake for certificate chain.

GROUPS

public static final OpenSslContextOption<java.lang.String[]> GROUPS

Set the groups that should be used. This will override curves set with -Djdk.tls.namedGroups.

See SSL_CTX_set1_groups_list.

TMP_DH_KEYLENGTH

public static final OpenSslContextOption<java.lang.Integer> TMP_DH_KEYLENGTH

Set the desired length of the Diffie-Hellman ephemeral session keys. This will override the key length set with -Djdk.tls.ephemeralDHKeySize.

The only supported values are 512, 1024, 2048, and 4096.

See SSL_CTX_set_tmp_dh_callback.
