Method Detail

isAvailable

public static boolean isAvailable()

Returns true if and only if netty-tcnative and its OpenSSL support are available.

isAlpnSupported

public static boolean isAlpnSupported()

Returns true if the used version of openssl supports ALPN.

isOcspSupported

public static boolean isOcspSupported()

Returns true if the used version of OpenSSL supports OCSP stapling.

version

public static int version()

Returns the version of the used available OpenSSL library or -1 if isAvailable() returns false.

versionString

public static java.lang.String versionString()

Returns the version string of the used available OpenSSL library or null if isAvailable() returns false.

ensureAvailability

public static void ensureAvailability()

Ensure that netty-tcnative and its OpenSSL support are available.

Throws:

java.lang.UnsatisfiedLinkError - if unavailable

unavailabilityCause

public static java.lang.Throwable unavailabilityCause()

Returns the cause of unavailability of netty-tcnative and its OpenSSL support.

Returns:

the cause if unavailable. null if available.

availableCipherSuites

@Deprecated
public static java.util.Set<java.lang.String> availableCipherSuites()

Deprecated. use availableOpenSslCipherSuites()

availableOpenSslCipherSuites

public static java.util.Set<java.lang.String> availableOpenSslCipherSuites()

Returns all the available OpenSSL cipher suites. Please note that the returned array may include the cipher suites that are insecure or non-functional.

availableJavaCipherSuites

public static java.util.Set<java.lang.String> availableJavaCipherSuites()

Returns all the available cipher suites (Java-style). Please note that the returned array may include the cipher suites that are insecure or non-functional.

isCipherSuiteAvailable

public static boolean isCipherSuiteAvailable(java.lang.String cipherSuite)

Returns true if and only if the specified cipher suite is available in OpenSSL. Both Java-style cipher suite and OpenSSL-style cipher suite are accepted.

supportsKeyManagerFactory

public static boolean supportsKeyManagerFactory()

Returns true if KeyManagerFactory is supported when using OpenSSL.

supportsHostnameValidation

public static boolean supportsHostnameValidation()

Returns true if Hostname Validation is supported when using OpenSSL.
