KeySpec
public class PKCS8EncodedKeySpec extends EncodedKeySpec
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
