public void setKeySize(int keyBits)

Overrides org.apache.poi.poifs.crypt.EncryptionHeader.setKeySize.

Doc from org.apache.poi.poifs.crypt.EncryptionHeader.setKeySize.

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
