      • 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.

      • 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
