RIPEMD-160 与 SHA-256
谁能解释一下 SHA-256 和 RIPEMD-160，哪种算法通常更快，性能和空间比较是什么（如果有）？ 我所说的空间比较并不是指 160 位和 256 位，而是指冲突频率、生产环境中空间要求的差异。以及计算两者的时间。 欧洲国家是否有 RIPEMD-160 要求？ 任何其他信息都有助于做出决定。
Can anyone shed some light into SHA-256 and RIPEMD-160, which algorithm is normally faster and what are the performance and space comparisons, if any?
By space comparisons I don't mean 160 bits and 256 bits, but what are the collisions frequency, difference in space requirements in production env. and time to calculate both.
Is RIPEMD-160 a requirement for European countries?
Any additional information, that would be helpful in deciding.

至于 SHA-256，没有已知的冲突。我相信，虽然在 SHA-1 中以比暴力破解更快的速度生成碰撞方面取得了一些进展，但这些进展仍然不实用，并且肯定不适用于 SHA-256。
我对 RIPEMD-160 不是很熟悉，所以我不能说太多。
As for SHA-256 there are no known collisions. I believe that while some advances have been made in generating collisions in SHA-1 faster than brute force, that those are still not practical and certainly not applicable for SHA-256.
I'm not very familiar with RIPEMD-160 so I cannot say much about it.
不。
No.
RIPMD-160可用于任何消息大小，而SHA仅限于2^64-1。RIPMD-160在此过程中需要 160 个步骤，而SHA仅需要 80 个步骤。因为我认为 RIPMD-160 更好。
RIPMD-160can be used to any message size whileSHAis limited to2^64-1.and
RIPMD-160takes 160 steps during the process whereasSHAtakes only 80.as I think
RIPMD-160is better.
