Affected Products and Keys by Infineon RSA vulnerability
Raw
infineon-roca.md

Collecting some information about the extend and affected products and keys of the Infineon RSA vulnerability (ROCA).

Estonian eID cards

Slovakian eID cards

Yubikeys

This blog post from 2016 is hillarious and argues that certified closed source is more secure than open source:

GPG keys

Vulnerable GPG keys are likely created by Yubikeys.

TPM chips

Various vendors, including Google, Fujitsu, HP, Lenovo. Probably more. This can affect Bitlocker keys (Windows encryption system).

SSH keys

Github found "447 fingerprinted keys, 237 of them factorizable" according to Ars Technica. Likely also generated by Yubikeys.

Electronic signatures / eIDAS

Several German providers of electronic signatures according to the EU eIDAS system have affected keys in their issuing certificates (Telekom, Sparkassenverlag / S-Trust, Bundesdruckerei / D-Trust, Datev, Deutsche Rentenversicherung).

TLS certificates

Not many according to Rob Stradlings tests. No CA certificates.

Gemalto

Information very unclear, no exact information about scale and affected products yet.
