Hash Function Lounge -[change source]

The Hash function lounge – a list of hash functions and known attacks - this reference is no longer valid.— This unsigned comment was added by (talk • changes) at 10:13, 30 October 2015‎.

Thank you for noticing. Luckily, I was able to find a link for where it had moved. It is updated. All the best, Fylbecatulous talk 13:13, 30 October 2015 (UTC)[reply]

The first characteristic listed ("It is extremely easy to calculate a hash for any given data") is not necessarily true. Some hash functions are deliberately designed to be expensive to compute, to thwart attackers attempting a brute force search for a collision. scrypt is one such algorithm.
