class:PKCS8EncodedKeySpec [NONE]
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
Since:
1.2

constructor:PKCS8EncodedKeySpec(byte[]) [NONE]

  • 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 - if encodedKey is null.

    • constructor:PKCS8EncodedKeySpec(byte[],java.lang.String) [NONE]

    PKCS8EncodedKeySpec

    public PKCS8EncodedKeySpec?(byte[] encodedKey, String algorithm)
    Creates a new PKCS8EncodedKeySpec with the given encoded key and algorithm. This constructor is useful when subsequent callers of the PKCS8EncodedKeySpec object 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 encodedKey or algorithm is null.
    IllegalArgumentException - if algorithm is the empty string ""
    Since:
    9

    method:getEncoded() [NONE]

  • getEncoded

    public byte[] getEncoded()
    Returns the key bytes, encoded according to the PKCS #8 standard.
    Overrides:
    getEncoded in class EncodedKeySpec
    Returns:
    the PKCS #8 encoding of the key. Returns a new array each time this method is called.

    • method:getFormat() [NONE]

    getFormat

    public final  String getFormat()
    Returns the name of the encoding format associated with this key specification.
    Specified by:
    getFormat in class EncodedKeySpec
    Returns:
    the string "PKCS#8".
