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:
