 public class PKCS8EncodedKeySpec extends EncodedKeySpec This class represents the ASN.1 encoding of a private key, encoded according to the ASN.1 typePrivateKeyInfo. ThePrivateKeyInfosyntax 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:

Constructor Detail- 
PKCS8EncodedKeySpecpublic PKCS8EncodedKeySpec(byte[] encodedKey) Creates a newPKCS8EncodedKeySpecwith 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- if- encodedKeyis null.

PKCS8EncodedKeySpecpublic PKCS8EncodedKeySpec(byte[] encodedKey, String algorithm)Creates a newPKCS8EncodedKeySpecwith the given encoded key and algorithm. This constructor is useful when subsequent callers of thePKCS8EncodedKeySpecobject might not know the algorithm of the private 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.
- algorithm- the algorithm name of the encoded private key See the KeyFactory section in the Java Security Standard Algorithm Names Specification for information about standard algorithm names.
- Throws:
- NullPointerException- if- encodedKeyor- algorithmis null.
- IllegalArgumentException- if- algorithmis the empty string- ""

Method Detail- 
getEncodedpublic byte[] getEncoded() Returns the key bytes, encoded according to the PKCS #8 standard.- Overrides:
- getEncodedin class- EncodedKeySpec
- Returns:
- the PKCS #8 encoding of the key. Returns a new array each time this method is called.
 
 - 
getFormatpublic final String getFormat() Returns the name of the encoding format associated with this key specification.- Specified by:
- getFormatin class- EncodedKeySpec
- Returns:
- the string "PKCS#8".
