equalsback to summary
public boolean equals(Object o)

Overrides java.lang.Object.equals.

Doc from java.lang.Object.equals.

Indicates whether some other object is "equal to" this one.

The equals method implements an equivalence relation on non-null object references:

  • It is reflexive: for any non-null reference value x, x.equals(x) should return true.
  • It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
  • It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
  • It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
  • For any non-null reference value x, x.equals(null) should return false.

An equivalence relation partitions the elements it operates on into equivalence classes; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.

Parameters
o:Object

the reference object with which to compare.

Returns:boolean

true if this object is the same as the obj argument; false otherwise.

extractBytesback to summary
private void extractBytes(byte[] encKey, int size, int offSet, BigInteger bI)
getAlgorithmback to summary
public String getAlgorithm()

Implements java.security.Key.getAlgorithm.

Doc from java.security.Key.getAlgorithm.

Returns the standard algorithm name for this key. For example, "DSA" would indicate that this key is a DSA key. See the key related sections (KeyFactory, KeyGenerator, KeyPairGenerator, and SecretKeyFactory) in the Java Security Standard Algorithm Names Specification for information about standard key algorithm names.

Returns:String

the name of the algorithm associated with this key.

getBagAttributeback to summary
public ASN1Encodable getBagAttribute(ASN1ObjectIdentifier oid)

Implements org.bouncycastle.jce.interfaces.PKCS12BagAttributeCarrier.getBagAttribute.

getBagAttributeKeysback to summary
public Enumeration<E> getBagAttributeKeys()

Implements org.bouncycastle.jce.interfaces.PKCS12BagAttributeCarrier.getBagAttributeKeys.

getDback to summary
public BigInteger getD()

Implements org.bouncycastle.jce.interfaces.ECPrivateKey.getD.

Doc from org.bouncycastle.jce.interfaces.ECPrivateKey.getD.

return the private value D.

getEncodedback to summary
public byte[] getEncoded()

Implements java.security.Key.getEncoded.

Return a PKCS8 representation of the key. The sequence returned represents a full PrivateKeyInfo object.

Returns:byte[]

a PKCS8 representation of the key.

getFormatback to summary
public String getFormat()

Implements java.security.Key.getFormat.

return the encoding format we produce in getEncoded().

Returns:String

the string "PKCS#8"

getParametersback to summary
public ECParameterSpec getParameters()

Implements org.bouncycastle.jce.interfaces.ECKey.getParameters.

Doc from org.bouncycastle.jce.interfaces.ECKey.getParameters.

return a parameter specification representing the EC domain parameters for the key.

getParamsback to summary
public ECParameterSpec getParams()

Implements java.security.interfaces.ECKey.getParams.

Doc from java.security.interfaces.ECKey.getParams.

Returns the domain parameters associated with this key. The domain parameters are either explicitly specified or implicitly created during key generation.

Returns:ECParameterSpec

the associated domain parameters.

getPublicKeyDetailsback to summary
private ASN1BitString getPublicKeyDetails(BCECGOST3410_2012PublicKey pub)
getSback to summary
public BigInteger getS()

Implements java.security.interfaces.ECPrivateKey.getS.

Doc from java.security.interfaces.ECPrivateKey.getS.

Returns the private value S.

Returns:BigInteger

the private value S.

hashCodeback to summary
public int hashCode()

Overrides java.lang.Object.hashCode.

Doc from java.lang.Object.hashCode.

Returns a hash code value for the 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

a hash code value for this object.

Implements org.bouncycastle.jce.interfaces.ECPointEncoder.setPointFormat.

Doc from org.bouncycastle.jce.interfaces.ECPointEncoder.setPointFormat.

Set the formatting for encoding of points. If the String "UNCOMPRESSED" is passed in point compression will not be used. If the String "COMPRESSED" is passed point compression will be used. The default is "UNCOMPRESSED".

Parameters

the style to use.
