getInstance

public static CipherInitializer getInstance()

initCipherDecryptProvider

protected void initCipherDecryptProvider()

isKeyBasedSymmetricEncryption

public boolean isKeyBasedSymmetricEncryption(String secretRepositoryEncryptionMode)

Checks whether symmetric encryption is configured using the provided encryption mode.

initEncrypt

public void initEncrypt()

Initializing the encryption key store which uses to encrypt the given plain text

handleException

protected static void handleException(String msg,
 Exception e)

handleException

protected static void handleException(String msg)

getIdentityKeyStoreWrapper

public org.wso2.securevault.keystore.IdentityKeyStoreWrapper getIdentityKeyStoreWrapper()

setIdentityKeyStoreWrapper

public void setIdentityKeyStoreWrapper(org.wso2.securevault.keystore.IdentityKeyStoreWrapper identityKeyStoreWrapper)

getEncryptionKeyWrapper

public org.wso2.securevault.encryption.EncryptionKeyWrapper getEncryptionKeyWrapper()

setTrustKeyStoreWrapper

public void setTrustKeyStoreWrapper(org.wso2.securevault.keystore.TrustKeyStoreWrapper trustKeyStoreWrapper)

getDecryptionProvider

public org.wso2.securevault.DecryptionProvider getDecryptionProvider()

getEncryptionProvider

public Cipher getEncryptionProvider()

getAlgorithm

public String getAlgorithm()

getInitializationVector

public byte[] getInitializationVector()

getGCMEncryptionProvider

public CipherInitializer.CipherWithIV getGCMEncryptionProvider()

Gets an encryption provider for GCM mode with a new IV. This method should be called for each GCM encryption operation to ensure that a unique key-IV combination is used, which is required for GCM security.

Returns:

A CipherWithIV instance containing both the Cipher and its corresponding IV
