Enum Constant Summary

Enum Constants

Enum Constant and Description
TLS_CIPHER_KMS_PQ_TLSv1_0_2019_06 Contains Draft Hybrid TLS Ciphers: https://tools.ietf.org/html/draft-campagna-tls-bike-sike-hybrid These ciphers perform two Key Exchanges (1 ECDHE + 1 Post-Quantum) during the TLS Handshake in order to combine the security of Classical ECDHE Key Exchange with the conjectured quantum-resistance of newly proposed key exchanges.
TLS_CIPHER_SYSTEM_DEFAULT Use whatever the System Default Preference is.

Method Summary

Modifier and Type	Method and Description
static TlsCipherPreference	valueOf(String name) Returns the enum constant of this type with the specified name.
static TlsCipherPreference[]	values() Returns an array containing the constants of this enum type, in the order they are declared.

Enum Constant Detail

TLS_CIPHER_SYSTEM_DEFAULT

public static final TlsCipherPreference TLS_CIPHER_SYSTEM_DEFAULT

Use whatever the System Default Preference is. This is usually the best option, as it will be automatically updated as the underlying OS or platform changes.

TLS_CIPHER_KMS_PQ_TLSv1_0_2019_06

public static final TlsCipherPreference TLS_CIPHER_KMS_PQ_TLSv1_0_2019_06

Contains Draft Hybrid TLS Ciphers: https://tools.ietf.org/html/draft-campagna-tls-bike-sike-hybrid These ciphers perform two Key Exchanges (1 ECDHE + 1 Post-Quantum) during the TLS Handshake in order to combine the security of Classical ECDHE Key Exchange with the conjectured quantum-resistance of newly proposed key exchanges. The algorithms these new Post-Quantum ciphers are based on have been submitted to NIST's Post-Quantum Crypto Standardization Process, and are still under review. This Cipher Preference may stop being supported at any time.

Method Detail

values

public static TlsCipherPreference[] 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 (TlsCipherPreference c : TlsCipherPreference.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static TlsCipherPreference 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
