Secure Digests

The Rebound Attack: Cryptanalysis of Reduced Whirlpool and Grøstl (Florian Mendel, Christian Rechberger, Martin Schlaffer, Søren Thomsen) --- prioritizing collision attacks to lower the try count

New Collision attacks Against Up To 24-step SHA-2 (Somitra Kumar Sanadhya, Palash Sarkar) --- the very first SHA-512 collisions exhibited.

On Corrective Patterns for the SHA-2 Family (Philip Hawkes, Michael Paddon, Gregory Rose) --- early paper on reducing efforts to produce SHA-2 collision

Cache missing for fun and profit (Colin Persival) --- leaking data from a secured thread via processor cache

The AES spec, as of 2001.

Several different hash implementations at etherhack.co.uk, and another whirlpool implementation at sunsean.com. Also check the Hash Function Lounge.
