A cryptographic hash function reading guide

After a few years of spectacular advances in breaking cryptographic hash function NIST has announced a competition to determine the next Secure Hash Algorithm, SHA-3. SHA-0 is considered broken, SHA-1 is still secure but no one knows for how long, and the SHA-2 family are desperately slow. (Do not even think about using MD5, or MD4 for which Prof. Wang can find collisions by hand, but RIPEMD-160 still stands).
