Enum Constant Detail

RSA_RSA

public static final SignatureAlgorithm RSA_RSA

RSA with PKCS#1 v1.5

This is the RSA with PKCS#1 v1.5 algorithm which is widely supported by cryptographic providers.

RSA_SSA_PSS

public static final SignatureAlgorithm RSA_SSA_PSS

RSA with SSA-PSS (PKCS#1 v2.1)

This algorithm is generally recommended because it is considered a more secure alternative to RSA_RSA. However, it is not supported by all cryptographic providers.

ECDSA

public static final SignatureAlgorithm ECDSA

Elliptic Curve Digital Signature Algorithm

This algorithm is generally recommended for new applications. However, it is not supported by all cryptographic providers.

Method Detail

values

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

Returns:

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

valueOf

public static SignatureAlgorithm valueOf(java.lang.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:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null
