extends EncodedKeySpec

java.lang.Object
   ↳ java.security.spec.EncodedKeySpec
     ↳ java.security.spec.PKCS8EncodedKeySpec


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
