The crypto API RNG framework is used to implement deterministic RNGs which in turn need seending from a noise source. The HW RNG framework is used for accessing RNGs which have their own noise source and provide random data with appropriate entropy. These RNGs are available via /dev/hwrng. > > Regards, > Mohan > This email and any attachments are intended for the sole use of the named > recipient(s) and contain(s) confidential information that may be > proprietary, privileged or copyrighted under applicable law.
