PKCS8EncodedKeySpec

java.lang.Object
- java.security.spec.EncodedKeySpec

public class PKCS8EncodedKeySpec extends EncodedKeySpec

This class represents the ASN.1 encoding of a private key, encoded according to the ASN.1 type PrivateKeyInfo. The PrivateKeyInfo syntax is defined in the PKCS#8 standard as follows:

PrivateKeyInfo ::= SEQUENCE {
version Version,
privateKeyAlgorithm PrivateKeyAlgorithmIdentifier,
privateKey PrivateKey,
attributes [0] IMPLICIT Attributes OPTIONAL }

Version ::= INTEGER

PrivateKeyAlgorithmIdentifier ::= AlgorithmIdentifier

PrivateKey ::= OCTET STRING

Attributes ::= SET OF Attribute

Fields Summary
Constructors Summary
public PKCS8EncodedKeySpec(byte[] encodedKey)
Creates a new PKCS8EncodedKeySpec with the given encoded key.
param
encodedKey the key, which is assumed to be encoded according to the PKCS #8 standard. The contents of the array are copied to protect against subsequent modification.
exception
NullPointerException if encodedKey is null.
super(encodedKey);
Methods Summary
public byte[] getEncoded()
Returns the key bytes, encoded according to the PKCS #8 standard.
return
the PKCS #8 encoding of the key. Returns a new array each time this method is called.
return super.getEncoded();
public final java.lang.String getFormat()
Returns the name of the encoding format associated with this key specification.
return
the string "PKCS#8".
return "PKCS#8";
