comment Why programming languages don't provide simple encryption methods?
@EthanHeilman Look at some encryption questions/answers on stackoverflow. Most of them have huge holes, such as no authentication(hello padding oracle) or constant IVs.

comment Guarding against cryptanalytic breakthroughs: combining multiple hash functions
But this question isn't really about H(H(x)) with H being the same hash in both cases.

comment Is such a crypto-system available?
Doesn't work. 1) k_new would be an encryption key, not a decryption key 2) f is invertable. So you can calculate k1 = k_new/k2.
