Enum EncType

java.lang.Object
java.lang.Enum<EncType>
net.i2p.crypto.EncType
All Implemented Interfaces:
Serializable, Comparable<EncType>, java.lang.constant.Constable
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.
Since:
0.9.18

  • Method Details

    • values

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

    • getParams

      public AlgorithmParameterSpec getParams() throws InvalidParameterSpecException
      The elliptic curve ECParameterSpec for ECDSA; DSAParameterSpec for DSA
      Throws:
      InvalidParameterSpecException - if the algorithm is not available on this JVM.

    • 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:
      true if supported in this JVM

    • getByCode

      public static EncType getByCode​(int code)
      Returns:
      null if not supported
