I'm not a fan of hardware key generation. :-)


https://en.wikipedia.org/wiki/YubiKey

"In October 2017, security researchers found a vulnerability (known as ROCA) in the implementation of RSA keypair generation in a cryptographic library used by a large number of Infineon security chips. The vulnerability allows an attacker to reconstruct the private key by using the public key.[18][19] All YubiKey 4, YubiKey 4C, and YubiKey 4 nano within the revisions 4.2.6 to 4.3.4 are affected by this vulnerability.[20] Yubico publicized a tool to check if a Yubikey is affected and replaces affected tokens for free.[21]"
