    Padding scheme of the cryptographic signature algorithm

    The signature algorithm is defined by the signing certificate's key type. For example, RSA or ECDSA. For some keys, e.g. RSA keys, there are different padding algorithms. Some cryptographic providers let you set this padding algorithm. However, this only has an effect on signatures created by the cryptographic provider itself. All signed data acquired from external sources may use other signing algorithms; more specifically, the issuer certificates of the trust chain, the time-stamp’s signature, or those used for the revocation information (CRL, OCSP). It is recommended to verify that the algorithms of all signatures provide a similar level of security.

    • Method Detail

      • values

        public static SignaturePaddingType[] 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 (SignaturePaddingType c : SignaturePaddingType.values())
    System.out.println(c);
        Returns:
        an array containing the constants of this enum type, in the order they are declared

      • valueOf

        public static SignaturePaddingType 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
