Class CryptorImpl

java.lang.Object
  com.stc.connector.ldapadapter.utils.cryptography.impl.CryptorImpl

All Implemented Interfaces:

Cryptor

public final class CryptorImpl
extends java.lang.Object
implements Cryptor

Provides a Cryptor implementation. The getInstance(Map aProperties) factory method returnes a new instance of this implementation each time. So it does not provide a singlton and does not pool any instances.

Use the CIPHER_KEY_ALIAS_PROPERTY_KEY, CIPHER_KEY_PASSWORD_PROPERTY_KEY, CIPHER_TRANSFORMATION_PROPERTY_KEY keys and the KEYSTORE_URL_PROPERTY_KEY, KEYSTORE_TYPE_PROPERTY_KEY, KEYSTORE_PASSWORD_PROPERTY_KEY keys defined in the KeyStoreUtil interface to set the desired values in the property map when acquiring an instance.

Method Detail

getInstance

public static Cryptor getInstance(java.util.Map aProperties)

This factory method returns a new instance of a Cryptor initializing it using the specified properties.

Use the CIPHER_KEY_ALIAS_PROPERTY_KEY, CIPHER_KEY_PASSWORD_PROPERTY_KEY, CIPHER_TRANSFORMATION_PROPERTY_KEY keys and the KEYSTORE_URL_PROPERTY_KEY, KEYSTORE_TYPE_PROPERTY_KEY, KEYSTORE_PASSWORD_PROPERTY_KEY keys defined in the KeyStoreUtil interface to set the desired values in the property map when acquiring an instance.

Parameters:

aProperties - The map view of the properties to use in getting the instance.

Returns:

A new Cryptor instance based on the specified properties.

encrypt

public byte[] encrypt(byte[] aData)

Description copied from interface: Cryptor

Encrypts the aData using a Cipher.

Specified by:

encrypt in interface Cryptor

Parameters:

aData - The data to be encrypted.

Returns:

byte[] The encrypted data.

See Also:

Cryptor.encrypt(byte[] aData).

decrypt

public byte[] decrypt(byte[] aData)

Description copied from interface: Cryptor

Decrypts the aData using a Cipher.

Specified by:

decrypt in interface Cryptor

Parameters:

aData - The encyrpted data.

Returns:

byte[] The decrypted data.

See Also:

Cryptor.decrypt(byte[] aData).

encodeBase64

public byte[] encodeBase64(byte[] aData)

Description copied from interface: Cryptor

Encodes the aData to Base64 encoded form.

Specified by:

encodeBase64 in interface Cryptor

Parameters:

aData - The data to be encoded in Base64.

Returns:

byte[] The encoded data.

See Also:

Cryptor.encodeBase64(byte[] aData).

decodeBase64

public byte[] decodeBase64(byte[] aData)

Description copied from interface: Cryptor

Decodes the Base64 encoded aData.

Specified by:

decodeBase64 in interface Cryptor

Parameters:

aData - The Base64 encoded data.

Returns:

byte[] The decoded data.

See Also:

Cryptor.decodeBase64(byte[] aData).

encryptAndEncodeBase64

public byte[] encryptAndEncodeBase64(byte[] aData)

Description copied from interface: Cryptor

Encrypts the aData using a Cipher and returns the results in Base64 encoded form. It uses methods encrypt and base64Encode in its implementation.

Specified by:

encryptAndEncodeBase64 in interface Cryptor

Parameters:

aData - The data to be encrypted.

Returns:

byte[] The encrypted data.

See Also:

Cryptor.encryptAndEncodeBase64(byte[] aData).

decodeBase64AndDecrypt

public byte[] decodeBase64AndDecrypt(byte[] aData)

Description copied from interface: Cryptor

Decrypts the Base64 encoded aData and then decrypts using the same Cipher that was used to encrypt it. This method will decrypt only the data that was encrypted using the encryptAndBase64Encode method of this interface. It uses methods base64Decode and decrypt in its implementation.

Specified by:

decodeBase64AndDecrypt in interface Cryptor

Parameters:

aData - The encyrpted data in Base64 encoded form.

Returns:

byte[] The decrypted data.

See Also:

Cryptor.decodeBase64AndDecrypt(byte[] aData).
