To our knowledge there is currently no third party software available to decrypt AxCrypt-encrypted files. However, anyone with the correct skills can create such software – the specifications are published and also the main AxCrypt software is open source.
You can always download and keep a backup copy of the standalone version of AxCrypt, or even the source code. That is all you need. You never need our servers or our company to be operating to decrypt an encrypted file.
