Constructor Detail

CryptoAPIEncryptionHeader

public CryptoAPIEncryptionHeader(LittleEndianInput is)
                          throws java.io.IOException
Throws:
java.io.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

Overrides:
setKeySize in class EncryptionHeader

clone

public CryptoAPIEncryptionHeader clone()
                                throws java.lang.CloneNotSupportedException
Overrides:
clone in class StandardEncryptionHeader
Throws:
java.lang.CloneNotSupportedException
