Method Details

getEncoded

public byte[] getEncoded()

Description copied from interface: AsymmetricKey

Return an ASN.1 encoding of the key wrapped in a PrivateKeyInfo or a SubjectPublicKeyInfo structure.

Specified by:

getEncoded in interface AsymmetricKey

Returns:

an encoding of a PrivateKeyInfo or a SubjectPublicKeyInfo structure.

getEncoded

public byte[] getEncoded(boolean withPointCompression)

getW

public ECPoint getW()

equals

public boolean equals(Object o)

Description copied from interface: Key

Return true if o is an equivalent key to this.

Specified by:

equals in interface Key

Overrides:

equals in class Object

Parameters:

o - object to compare to.

Returns:

true if o is the same or equivalent key, false otherwise.

hashCode

public int hashCode()

Description copied from interface: Key

Return the hashCode for the key.

Specified by:

hashCode in interface Key

Overrides:

hashCode in class Object

Returns:

the key's hashCode.
