[PATCH 0/2] add crypto support for TPM communication

2018-03-01 Thread James Bottomley
To support cryptographic communication with the TPM, we need to add Cipher FeedBack (CFB) mode for stream encryption because this is the mandated encryption scheme for all encrypted parameters and responses.  Additionally, we ran across a problem in the elliptic curve routines in that the size of t
