^ Method Detail ^ 



 === setKeyCipher === 
void **setKeyCipher**([[javacard:java-card-api:Cipher|Cipher]]  keyCipher)

Sets the Cipher object to be used to decrypt the input key data
 and key parameters in the set methods.
 Default Cipher object is null - no decryption performed.

 
 

**Parameters:**keyCipher - the decryption Cipher object to decrypt the input key data.
 The null parameter indicates that no decryption is required.

 === getKeyCipher === 
[[javacard:java-card-api:Cipher|Cipher]]  **getKeyCipher**()

Returns the Cipher object to be used to decrypt the input key data
 and key parameters in the set methods.
 Default is null - no decryption performed.

 
 


**Returns:**keyCipher, the decryption Cipher object to decrypt the input key data.
 The null return indicates that no decryption is performed.
