java.lang.Objectjavax.crypto.EncryptedPrivateKeyInfo
public class EncryptedPrivateKeyInfo
An implementation of the EncryptedPrivateKeyInfo ASN.1
type as specified in PKCS #8 -
Private-Key Information Syntax Standard.
The ASN.1 type EncryptedPrivateKeyInfo is:
EncryptedPrivateKeyInfo ::= SEQUENCE {
encryptionAlgorithm EncryptionAlgorithmIdentifier,
encryptedData EncryptedData }
EncryptionAlgorithmIdentifier ::= AlgorithmIdentifier
EncrytpedData ::= OCTET STRING
AlgorithmIdentifier ::= SEQUENCE {
algorithm OBJECT IDENTIFIER,
parameters ANY DEFINED BY algorithm OPTIONAL }
PKCS8EncodedKeySpec| Constructor Summary | |

|
EncryptedPrivateKeyInfo(byte[] encoded)
Create a new EncryptedPrivateKeyInfo from an encoded
representation, parsing the ASN.1 sequence. |

public EncryptedPrivateKeyInfo(AlgorithmParameters params,
byte[] encryptedData)
throws IllegalArgumentException,
NoSuchAlgorithmException
EncryptedPrivateKeyInfo object from raw
encrypted data and the parameters used for encryption.
The encryptedData array is cloned.
params - The encryption algorithm parameters.encryptedData - The encrypted key data.
IllegalArgumentException - If the
encryptedData array is empty (zero-length).
NoSuchAlgorithmException - If the algorithm
specified in the parameters is not supported.
NullPointerException - If encryptedData
is null.
public EncryptedPrivateKeyInfo(byte[] encoded)
throws IOException
EncryptedPrivateKeyInfo from an encoded
representation, parsing the ASN.1 sequence.
encoded - The encoded info.
IOException - If parsing the encoded data fails.
NullPointerException - If encoded is
null.
public EncryptedPrivateKeyInfo(String algName,
byte[] encryptedData)
throws IllegalArgumentException,
NoSuchAlgorithmException,
NullPointerException
EncryptedPrivateKeyInfo from the cipher
name and the encrytpedData.
The encryptedData array is cloned.
algName - The name of the algorithm (as an object identifier).encryptedData - The encrypted key data.
IllegalArgumentException - If the
encryptedData array is empty (zero-length).
NoSuchAlgorithmException - If algName is not
the name of a supported algorithm.
