public NoopEncryptionSpi()

Method Detail

masterKeyDigest

public byte[] masterKeyDigest()

Returns master key digest. Should always return same digest for a same key. Digest used for a configuration consistency check.

Specified by:

masterKeyDigest in interface EncryptionSpi

Returns:

Master key digest.

create

public Serializable create()
                    throws IgniteException

Creates new key for an encryption/decryption of cache persistent data: pages, WAL records.

Specified by:

create in interface EncryptionSpi

Returns:

Newly created encryption key.

Throws:

IgniteException - If key creation failed.

encrypt

public void encrypt(ByteBuffer data,
                    Serializable key,
                    ByteBuffer res)

Encrypts data.

Specified by:

encrypt in interface EncryptionSpi

Parameters:

data - Data to encrypt.

key - Encryption key.

res - Destination buffer.

encryptNoPadding

public void encryptNoPadding(ByteBuffer data,
                             Serializable key,
                             ByteBuffer res)

Encrypts data without padding info.

Specified by:

encryptNoPadding in interface EncryptionSpi

Parameters:

data - Data to encrypt.

key - Encryption key.

res - Destination buffer.

decrypt

public byte[] decrypt(byte[] data,
                      Serializable key)

Decrypts data encrypted with EncryptionSpi.encrypt(ByteBuffer, Serializable, ByteBuffer)

Specified by:

decrypt in interface EncryptionSpi

Parameters:

data - Data to decrypt.

key - Encryption key.

decryptNoPadding

public void decryptNoPadding(ByteBuffer data,
                             Serializable key,
                             ByteBuffer res)

Decrypts data encrypted with EncryptionSpi.encryptNoPadding(ByteBuffer, Serializable, ByteBuffer)

Specified by:

decryptNoPadding in interface EncryptionSpi

Parameters:

data - Data to decrypt.

key - Encryption key.

encryptKey

public byte[] encryptKey(Serializable key)

Encrypts key. Adds some info to check key integrity on decryption.

Specified by:

encryptKey in interface EncryptionSpi

Parameters:

key - Key to encrypt.

Returns:

Encrypted key.

decryptKey

public Serializable decryptKey(byte[] key)

Decrypts key and checks it integrity.

Specified by:

decryptKey in interface EncryptionSpi

Parameters:

key - Key to decrypt.

Returns:

Encrypted key.

encryptedSize

public int encryptedSize(int dataSize)

Specified by:

encryptedSize in interface EncryptionSpi

Parameters:

dataSize - Size of plain data in bytes.

Returns:

Size of encrypted data in bytes for padding encryption mode.

encryptedSizeNoPadding

public int encryptedSizeNoPadding(int dataSize)

Specified by:

encryptedSizeNoPadding in interface EncryptionSpi

Parameters:

dataSize - Size of plain data in bytes.

Returns:

Size of encrypted data in bytes for nopadding encryption mode.

blockSize

public int blockSize()

Specified by:

blockSize in interface EncryptionSpi

Returns:

Encrypted data block size.

spiStart

public void spiStart(@Nullable
                     @Nullable String igniteInstanceName)
              throws IgniteSpiException

This method is called to start SPI. After this method returns successfully kernel assumes that SPI is fully operational.

Specified by:

spiStart in interface IgniteSpi

Parameters:

igniteInstanceName - Name of Ignite instance this SPI is being started for (null for default Ignite instance).

Throws:

IgniteSpiException - Throws in case of any error during SPI start.

spiStop

public void spiStop()
             throws IgniteSpiException

This method is called to stop SPI. After this method returns kernel assumes that this SPI is finished and all resources acquired by it are released.

Note that this method can be called at any point including during recovery of failed start. It should make no assumptions on what state SPI will be in when this method is called.

Specified by:

spiStop in interface IgniteSpi

Throws:

IgniteSpiException - Thrown in case of any error during SPI stop.
