public Class BCMcEliecePrivateKey

Overrides java.lang.Object.equals.

Compare this key with another object.

Parameters

other:Object

the other object

Returns:boolean

the result of the comparison

Implements java.security.Key.getAlgorithm.

Return the name of the algorithm.

Returns:String

"McEliece"

Implements java.security.Key.getEncoded.

Return the key data to encode in the SubjectPublicKeyInfo structure.

The ASN.1 definition of the key structure is

  McEliecePrivateKey ::= SEQUENCE {
    n          INTEGER                   -- length of the code
    k          INTEGER                   -- dimension of the code
    fieldPoly  OCTET STRING              -- field polynomial defining GF(2ˆm)
    getGoppaPoly()  OCTET STRING              -- irreducible Goppa polynomial
    sInv       OCTET STRING              -- matrix Sˆ-1
    p1         OCTET STRING              -- permutation P1
    p2         OCTET STRING              -- permutation P2
    h          OCTET STRING              -- canonical check matrix
    qInv       SEQUENCE OF OCTET STRING  -- matrix used to compute square roots
  }

Returns:byte[]

the key data to encode in the SubjectPublicKeyInfo structure

Returns:GF2mField

the finite field

Implements java.security.Key.getFormat.

Doc from java.security.Key.getFormat.

Returns the name of the primary encoding format of this key, or null if this key does not support encoding. The primary encoding format is named in terms of the appropriate ASN.1 data format, if an ASN.1 specification for this key exists. For example, the name of the ASN.1 data format for public keys is SubjectPublicKeyInfo, as defined by the X.509 standard; in this case, the returned format is "X.509". Similarly, the name of the ASN.1 data format for private keys is PrivateKeyInfo, as defined by the PKCS #8 standard; in this case, the returned format is "PKCS#8".

Returns:String

the primary encoding format of the key.

Returns:PolynomialGF2mSmallM

the irreducible Goppa polynomial

Returns:GF2Matrix

the canonical check matrix

Returns:int

the dimension of the code

Returns:int

the length of the code

Returns:Permutation

the permutation used to generate the systematic check matrix

Returns:Permutation

the permutation used to compute the public generator matrix

Returns:PolynomialGF2mSmallM[]

the matrix for computing square roots in (GF(2^m))^t

Returns:GF2Matrix

the k x k random binary non-singular matrix S

Overrides java.lang.Object.hashCode.

Doc from java.lang.Object.hashCode.

Returns a hash code value for this object. This method is supported for the benefit of hash tables such as those provided by java.util.HashMap.

The general contract of hashCode is:

• Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
• If two objects are equal according to the equals method, then calling the hashCode method on each of the two objects must produce the same integer result.
• It is not required that if two objects are unequal according to the equals method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.

Returns:int

the hash code of this key
