Enum EncType

  • All Implemented Interfaces:
    Serializable, Comparable<EncType>
    public enum EncType
extends Enum<EncType>
    Defines the properties for various encryption types that I2P supports or may someday support. All PublicKeys and PrivateKeys have a type. Note that a EncType specifies both an algorithm and parameters, so that we may change primes or curves for a given algorithm.

    • Method Detail

      • values

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

      • valueOf

        public static EncType 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

      • getCode

        public int getCode()
        the unique identifier for this type

      • getPubkeyLen

        public int getPubkeyLen()
        the length of the public key, in bytes

      • getPrivkeyLen

        public int getPrivkeyLen()
        the length of the private key, in bytes

      • getBaseAlgorithm

        public EncAlgo getBaseAlgorithm()
        the standard base algorithm name used for the Java crypto factories

      • getAlgorithmName

        public String getAlgorithmName()
        the standard name used for the Java crypto factories

      • getSupportedSince

        public String getSupportedSince()
        The router version in which this type was first supported.

      • isAvailable

        public boolean isAvailable()
        Returns:
        true if supported in this JVM

      • isAvailable

        public static boolean isAvailable​(int code)
        Returns:
        true if supported in this JVM

      • isAvailable

        public static boolean isAvailable​(String stype)
        Parameters:
        stype - number or name
        Returns:
