I have used nitrokeys and FST-01, the FST-01 beats the nitrokey in speed and in freedom, i currently use two of them, one with rsa 4096 and one with 25519 (for decryption you need libgcrypt 1.7). The nitrokey beats the FST-01 in the case, it&#x27;s by default more weareable without need to make your own one.<p>It seems there is a big plus when you use a board made by the person who makes gnuk which is the same person who makes the smartcard gnupg code.
