okay bestie, welcome to tpmtoken_protect 💅 it lives in the General Commands Manual section and it's your girl for locking up (or unlocking!) your data with a key that the TPM itself is babysitting. no cap. 🔐

✨ NAME ✨

tpmtoken_protect — encrypt or decrypt data using a symmetric key stored in the user's TPM PKCS#11 data store 🦋

🌸 SYNOPSIS 🌸

tpmtoken_protect [ OPTION ]

👑 DESCRIPTION 👑

so like, tpmtoken_protect will encrypt or decrypt</> your data using a symmetric key that's chillin' in the user's data store. the key doing all the protecting is a 256-bit AES key stored as a private Secret Key PKCS#11 object ✨

that object has the PKCS#11 label attribute of User Data Protection Key — that's its whole name, iconic, no notes 💖

the key is generated by the TPM PKCS#11 implementation when it is needed the first time. and because it's generated as a private object, it's protected by the TPM on the platform. main character security fr fr 🔥
