Which hash cipher is the most... Complex?

Answer 1

If you need to raise the complexity of the hash calculation (for example, to slow down brute force), you usually take a good, strong hash function (see the list in paran0id 's answer ) and build a Key derivation function (KDF) based on it . The basic principle is multiple hashing with the addition of a salt. The number of iterations can control the complexity, and the salt is needed to make precalculations useless.
There are KDFs aimed at "devouring" not only processor time, but also large amounts of memory; e.g. Scrypt.
