Are IIPP cryptography routine parameters memory-secured?

Hi,

When I call a cryptographic routine, i.e.

ippsRijndael128Init(mMasterKey, IppsRijndaelKey128, mCryptoCtx),

Does the first parameter- the master key, is securely stored in memory(stack) or not?

If it is secured, in which method?

Thanks in advance!

Can't anyone in Intel answer my question?

I think this matter is important enough and could interest alot of users.

Hi,

Some comments from our Crypto function export:

The parameter mMasterKey is really master key. And user himself should care about it secure. RijndaelInit function converts mMasterKey into some key material been stored in the context mCryptoCtx. Other (encrypt/decrypt) operations need not and doesn't use mMasterKey. Instead they use key material.
