什么是"e是65537(0x10001)"?意思是? [英] What does "e is 65537 (0x10001)" mean?

问题描述

我想知道输出e is 65537 (0x10001)的含义.它在使用openssl genrsa的RSA密钥生成期间发生.我知道这些点表示该数字已通过探针除法，并且在通过Miller Rabin检验后才打印出加号.但是我无法弄清楚在打印出RSA密钥之前的最后一条消息是什么意思.

I want to know what the output e is 65537 (0x10001) means. It happens during the RSA Key Generation using openssl genrsa. I know that the dots mean that the number has passed a probe division and the plus is printed out after it passed a miller rabin test. But i can't figure out what the last info message before the RSA key is printed out means.

我在openssl文档中找不到它.我可以在有关素数生成的学期论文中使用它.谢谢你的帮助！ :)

I can't find it in the openssl docs. And I could use it in term paper on prime number generation. Thanks for your help! :)

推荐答案

"e"是公共指数，在openssl genrsa中，可以使用选项-F4或-3在65537和3之间选择.

The "e" is the public exponent, in openssl genrsa, you can use the option -F4 or -3 to choose between 65537 and 3.
