Class PKCS8EncryptedPrivateKeyInfo

java.lang.Object
org.bouncycastle.pkcs.PKCS8EncryptedPrivateKeyInfo
public class PKCS8EncryptedPrivateKeyInfo extends Object
Holding class for a PKCS#8 EncryptedPrivateKeyInfo structure (RFC 5958, originally RFC 5208).

  • Constructor Details

    • PKCS8EncryptedPrivateKeyInfo

      public PKCS8EncryptedPrivateKeyInfo(org.bouncycastle.asn1.pkcs.EncryptedPrivateKeyInfo encryptedPrivateKeyInfo)
      Wrap an existing parsed EncryptedPrivateKeyInfo structure.
      Parameters:
      encryptedPrivateKeyInfo - the ASN.1 structure to wrap.

    • PKCS8EncryptedPrivateKeyInfo

      public PKCS8EncryptedPrivateKeyInfo(byte[] encryptedPrivateKeyInfo) throws IOException
      Parse a BER/DER encoded EncryptedPrivateKeyInfo.
      Parameters:
      encryptedPrivateKeyInfo - the encoded bytes.
      Throws:
      IOException - if the data is not a valid EncryptedPrivateKeyInfo encoding.

  • Method Details

    • getEncryptionAlgorithm

      public org.bouncycastle.asn1.x509.AlgorithmIdentifier getEncryptionAlgorithm()
      Return the algorithm identifier describing how the private key has been encrypted.

    • getEncryptedData

      public byte[] getEncryptedData()
      Return the raw ciphertext bytes of the encrypted private key.

    • toASN1Structure

      public org.bouncycastle.asn1.pkcs.EncryptedPrivateKeyInfo toASN1Structure()
      Return the underlying ASN.1 structure for this holder.

    • getEncoded

      public byte[] getEncoded() throws IOException
      Return the default (DER) encoding of this EncryptedPrivateKeyInfo.
      Returns:
      the encoded bytes.
      Throws:
      IOException - if encoding fails.

    • decryptPrivateKeyInfo

      public org.bouncycastle.asn1.pkcs.PrivateKeyInfo decryptPrivateKeyInfo(InputDecryptorProvider inputDecryptorProvider) throws PKCSException
      Decrypt the wrapped private key.
      Parameters:
      inputDecryptorProvider - provider able to produce a decryptor matching the encryption algorithm carried by this object.
      Returns:
      the recovered PrivateKeyInfo.
      Throws:
      PKCSException - if a decryptor cannot be created or decryption / parsing fails.
