Automatic data encryption and decryption with Clevis and Tang

Passing Secrets

Conclusions

Data can be decrypted in a completely automatic process using Clevis and Tang. Clevis relies on Tang, so the data decryption only works if the Tang server is available. Under no circumstances does the actual key cross the wire; instead, it is recalculated during the recovery process. Policies can be defined using the SSS algorithm so that different data encryption and decryption methods are used where necessary.
