PKCS8EncodedKeySpec (Java Platform SE 6) (original) (raw)
java.security.spec
Class PKCS8EncodedKeySpec
java.lang.Object
java.security.spec.EncodedKeySpec
java.security.spec.PKCS8EncodedKeySpec
All Implemented Interfaces:
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
Since:
1.2

PKCS8EncodedKeySpec
public PKCS8EncodedKeySpec(byte[] encodedKey)
Creates a new PKCS8EncodedKeySpec with the given encoded key.
Parameters:
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.
Throws:
[NullPointerException](../../../java/lang/NullPointerException.html "class in java.lang") - if encodedKey is null.

getEncoded
public byte[] getEncoded()
Returns the key bytes, encoded according to the PKCS #8 standard.
Overrides:
[getEncoded](../../../java/security/spec/EncodedKeySpec.html#getEncoded%28%29) in class [EncodedKeySpec](../../../java/security/spec/EncodedKeySpec.html "class in java.security.spec")
Returns:
the PKCS #8 encoding of the key. Returns a new array each time this method is called.
getFormat
public final String getFormat()
Returns the name of the encoding format associated with this key specification.
Specified by:
[getFormat](../../../java/security/spec/EncodedKeySpec.html#getFormat%28%29) in class [EncodedKeySpec](../../../java/security/spec/EncodedKeySpec.html "class in java.security.spec")
Returns:
the string "PKCS#8".
