问题
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.
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! :)
回答1:
The "e" is the public exponent, in openssl genrsa, you can use the option -F4 or -3 to choose between 65537 and 3.
For information on public exponent, you may take a look on this question: https://security.stackexchange.com/questions/2335/should-rsa-public-exponent-be-only-in-3-5-17-257-or-65537-due-to-security-c
