Enum Class HashToCurveProfile

java.lang.Object
java.lang.Enum<HashToCurveProfile>
org.bouncycastle.crypto.hash2curve.HashToCurveProfile
All Implemented Interfaces:
Serializable, Comparable<HashToCurveProfile>, Constable
public enum HashToCurveProfile extends Enum<HashToCurveProfile>
Supported profiles for instantiating an instance of HashToEllipticCurve. Each profile supports both hash_to_curve and encode_to_curve operations, according to RFC 9380

_NU_ is identical to _RO_, except that the encoding type is encode_to_curve. encode_to_curve is not yet implemented in this lib, thus these options are not yet included

    • values

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

    • valueOf

      public static HashToCurveProfile valueOf(String name)
      Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (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 class has no constant with the specified name
      NullPointerException - if the argument is null

    • getK

      public int getK()
      Retrieves the security level in bits associated with this instance.
      Returns:
      the value of the field 'k' representing security level in bits

    • getL

      public int getL()
      Retrieves the value of the field 'L' representing the internal block size in bytes associated with this instance.
      Returns:
      the value of the field 'L' representing the internal block size

    • getZ

      public BigInteger getZ()
      Retrieves the value of the field 'Z'.
      Returns:
      the value of the field 'Z' as a BigInteger

    • getH

      public int getH()
      Retrieves the value of the field 'h', representing the cofactor associated with this instance.
      Returns:
      the value of the field 'h' as an integer

    • getmJ

      public Integer getmJ()
      Retrieves the value of the field 'mJ' representing the associated Montgomery equation parameter A
      Returns:
      the value of the field 'mJ' as an Integer

    • getmK

      public Integer getmK()
      Retrieves the value of the field 'mK' representing the associated Montgomery equation parameter B specific to the hash-to-curve profile.
      Returns:
      the value of the field 'mK' as an Integer
