If a random salt generator is used, this decryption operation will expect to find an unencrypted salt at the beginning of the encrypted input, so that the decryption operation can be correctly performed (there is no other way of knowing it).
@param encryptedMessage the String message to be decrypted @return the result of decryption @throws EncryptionOperationNotPossibleException if the decryption operation fails, ommitting any further information about the cause for security reasons. @throws EncryptionInitializationException if initialization could notbe correctly done (for example, no password has been set).
