Re: Opinions on RIPEMD vs SHA?

2009-07-08 Thread Robert J. Hansen
I'm considering making my default hash RIPEMD160: does anyone have any opinions on how this compares to SHA-2 algorithms in terms of both security and availability? The new SHAs have the benefit of about a dozen years of cryptanalytic research behind them. RIPEMD160 is very similar to SHA-1,

I'm considering making my default hash RIPEMD160: does anyone have any opinions on how this compares to SHA-2 algorithms in terms of both security and availability? I like the idea that RIPEMD was developed in an academic community instead of the NSA, but if there are genuine benefits to using SHA,
