All Implemented Interfaces:
KeySpec

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

Constructor:

Constructor:
public PKCS8EncodedKeySpec(byte[] encodedKey) { super(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. exception: `NullPointerException` - if `encodedKey` is null.

 public PKCS8EncodedKeySpec(byte[] encodedKey) {
        super(encodedKey);
}

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.

exception: NullPointerException - if encodedKey is null.
