X509EncodedKeySpec

public class X509EncodedKeySpec extends EncodedKeySpec

This class represents the ASN.1 encoding of a public key, encoded according to the ASN.1 type SubjectPublicKeyInfo. The SubjectPublicKeyInfo syntax is defined in the X.509 standard as follows:

 SubjectPublicKeyInfo ::= SEQUENCE {
   algorithm AlgorithmIdentifier,
   subjectPublicKey BIT STRING }

Public Constructors

public X509EncodedKeySpec (byte[] encodedKey)

Creates a new X509EncodedKeySpec with the given encoded key.

Parameters

encodedKey	the key, which is assumed to be encoded according to the X.509 standard. The contents of the array are copied to protect against subsequent modification.

Throws

NullPointerException	if encodedKey is null.
