```
public static SslProvider[] values()
```
    Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
```
 for (SslProvider c : SslProvider.values())   System.out.println(c); 
```
    Returns:
    
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static SslProvider valueOf(String name)
```
    Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
    
    Parameters:
    
    name - the name of the enum constant to be returned.
    
    Returns:
    
    the enum constant with the specified name
    
    Throws:
    
    IllegalArgumentException - if this enum type has no constant with the specified name
    
    NullPointerException - if the argument is null
  - isAlpnSupported
```
public static boolean isAlpnSupported(SslProvider provider)
```
    Returns true if the specified SslProvider supports TLS ALPN Extension, false otherwise.
  - isTlsv13Supported
```
public static boolean isTlsv13Supported(SslProvider sslProvider)
```
    Returns true if the specified SslProvider supports TLS 1.3, false otherwise.
  - isTlsv13Supported
```
public static boolean isTlsv13Supported(SslProvider sslProvider, Provider provider)
```
    Returns true if the specified SslProvider supports TLS 1.3, false otherwise.
  - isOptionSupported
```
public static boolean isOptionSupported(SslProvider sslProvider, SslContextOption<?> option)
```
    Returns true if the specified SslProvider supports the specified SslContextOption, false otherwise.
