RSA 128位密钥长度需要多长时间? [英] How long would it take to factor a RSA 128-bit key length?

问题描述

我已经在线进行了一些研究，似乎表明RSA加密的建议密钥长度为1024位.但是我有一个问题，要使用今天的普通计算机将128位RSA密钥长度考虑在内需要多长时间?有可能吗?需要多长时间?

Ive done some research online and it seems to suggest the recommended key length for RSA encryption is 1024-bits. However i have a question as to how long would it take to factor a 128-bit RSA key length with an average computer used today? Is it possible and how long would it take?

非常感谢您在这个问题上能给我提供的帮助！

Would much appreciate any help you could give me on this question!

推荐答案

整数分解算法的实现，例如 GMP-CGM )只需几秒钟即可计算出商品硬件上128位RSA密钥的因子.

a implementation of a integer factorization algorithm like elliptic curve method (like GMP-CGM) will take a couple of seconds tops to compute the factors of a 128-bit RSA key on commodity hardware.
