AppStore approval and md5

I'm using md5 from <CommonCrypto/CommonDigest.h>.

I don't use it for encryption purposes.

I know that in submitting an app to AppStore, it's asked if the app开发者_C百科 uses encryption.

Is this the case to answer yes?

MD5 is not an encryption algorithm, it's a hashing algorithm. Encryption has to be reversible.

As it is not an encyrption, you can say "No" without hesitation.

I use CC_MD5 in my projects too. I always say "No" when asked if the app uses encryption just before submitting. None of them rejected so far.
