# This script condensates the receipt found at https://incenp.org/notes/2020/tpm-based-ssh-key.html
# for an archlinux system. Running it will eventually install the dependencies, initialize the
# tpm2_pkcs11 store and generate a token and a key. From the key, an ssh public key will be generated.
# You can customize the some setting with env variables: KEY_PATH overrides the default path where the
# key is stored (~/.ssh/tpm2.key); with KEY_ALGO you can override the algorithm used to generate the key

From Aegis to pass

[Aegis][0] is a nice android app to manage OTP tokens. [pass][1] is the password manager for *nix systems. I know that the whole point of the two factor authentication philosophy is to physically separate the bearers of authentication information, but the lifetime of my physical devices is quite random, so WHATEVER: I concoted this procedure to copy the OTP passwords from aegis to pass.
