Throws:

IOException

Method Detail

setKeySize

public void setKeySize(int keyBits)

Description copied from class: EncryptionHeader

Sets the keySize (in bits). Before calling this method, make sure to set the cipherAlgorithm, as the amount of keyBits gets validated against the list of allowed keyBits of the corresponding cipherAlgorithm

clone

public CryptoAPIEncryptionHeader clone()
                                throws CloneNotSupportedException

Overrides:

clone in class StandardEncryptionHeader

Throws:

CloneNotSupportedException
