BLAKE2: simpler, smaller, fast as MD5
'We present the cryptographic hash function BLAKE2, an improved version
of the SHA-3 finalist BLAKE optimized for speed in software. Target applications include
cloud storage, intrusion detection, or version control systems. BLAKE2 comes
in two main flavors: BLAKE2b is optimized for 64-bit platforms, and BLAKE2s for
smaller architectures. On 64-bit platforms, BLAKE2 is often faster than MD5, yet provides
security similar to that of SHA-3. We specify parallel versions BLAKE2bp and
BLAKE2sp that are up to 4 and 8 times faster, by taking advantage of SIMD and/or
multiple cores. BLAKE2 has more benefits than just speed: BLAKE2 uses up to 32%
less RAM than BLAKE, and comes with a comprehensive tree-hashing mode as well
as an efficient MAC mode.'

s3git
git for Cloud Storage. Create distributed, decentralized and versioned repositories that scale infinitely to 100s of millions of files and PBs of storage. Huge repos can be cloned on your local SSD for making changes, committing and pushing back. Oh yeah, and it dedupes too due to BLAKE2 Tree hashing. http://s3git.org
