What use are the hidden volumes if it is already pretty obvious that they will be there? I am pretty sure that whichever party you are trying to protect yourself from with this, will know that a Nitrokey will have hidden volumes.

- gruez 7y agoHow does this work with SSDs supporting TRIM? If it's enabled, that large block of space would be erased by the SSD. If you put a large file in its place, that's also suspicious (huge block of random data). If you disable TRIM, also suspicious.
- szszszsz 7y agoNitrokey Storage uses SD card, which AFAIK does not support TRIM. Before first usage it is overwritten with a random data. Drive is presented to the OS like any regular (non-SSD) flash drive device, hence I do not think OS would issue TRIM on it.
- mosselman 7y agoI get the technology and with a random disk it could make sense: there is no way to prove that there will be a hidden volume. But if you use this with a device that was built to support this, the plausible deniability becomes less believable.
