Enum Constant Detail

ecp256

public static final CertificateBuilder.Algorithm ecp256

The NIST P-256 elliptic curve algorithm, offer fast key generation, signing, and verification, with small keys and signatures, at 128-bits of security strength.

This algorithm is older than the Edwards curves, and are more widely supported.

ecp384

public static final CertificateBuilder.Algorithm ecp384

The NIST P-384 elliptic curve algorithm, offer fast key generation, signing, and verification, with small keys and signatures, at 192-bits of security strength.

rsa2048

public static final CertificateBuilder.Algorithm rsa2048

The 2048-bit RSA algorithm offer roughly 112-bits of security strength, at the cost of large keys and slightly expensive key generation.

This algorithm enjoy the widest support and compatibility, though.

rsa3072

public static final CertificateBuilder.Algorithm rsa3072

The 3072-bit RSA algorithm offer roughly 128-bits of security strength, at the cost of large keys and fairly expensive key generation.

RSA enjoy pretty wide compatibility, though not all systems support keys this large.

rsa4096

public static final CertificateBuilder.Algorithm rsa4096

The 4096-bit RSA algorithm offer roughly greater than 128-bits of security strength, at the cost of large keys and very expensive key generation.

RSA enjoy pretty wide compatibility, though not all systems support keys this large.

rsa8192

public static final CertificateBuilder.Algorithm rsa8192

The 8192-bit RSA algorithm offer roughly greater than 192-bits of security strength, at the cost of very large keys and extremely expensive key generation.

RSA enjoy pretty wide compatibility, though not all systems support keys this large.

ed25519

public static final CertificateBuilder.Algorithm ed25519

The Ed25519 algorithm offer fast key generation, signing, and verification, with very small keys and signatures, at 128-bits of security strength.

This algorithm is relatively new, require Java 15 or newer, and may not be supported everywhere.

ed448

public static final CertificateBuilder.Algorithm ed448

The Ed448 algorithm offer fast key generation, signing, and verification, with small keys and signatures, at 224-bits of security strength.

This algorithm is relatively new, require Java 15 or newer, and may not be supported everywhere.

Method Detail

values

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

Returns:

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

valueOf

public static CertificateBuilder.Algorithm 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

generateKeyPair

public KeyPair generateKeyPair(SecureRandom secureRandom)
                        throws GeneralSecurityException

Throws:

GeneralSecurityException
