Class PKCS8EncodedKeySpec
java.lang.Object
java.security.spec.EncodedKeySpec
java.security.spec.PKCS8EncodedKeySpec
- All Implemented Interfaces:
- KeySpec
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
