Given that SHA-1 collision was proven, what are the implications for other hash functions using the same digest size, specifically for RIPEMD-160? It is still relatively safe, or should it be replaced with RIPEMD-256 or SHA-2?
1 Answer
The SHA-1 collision was based on some weakness of the SHA-1 hash. This is what makes it 100,000 faster than the brute force attack.¹ Different hash functions will probably not have the same issue, although I would make plans for replacing them.
