Description Akihiro Nomura 2012-07-18 02:48:44 UTC

Description of problem:
man moduli says:
 4     Sophie Germain; (p+1)*2 is also prime.
but, (p+1)*2 is obviously NOT a prime.
It should be p*2+1.
http://mathworld.wolfram.com/SophieGermainPrime.html

Version-Release number of selected component (if applicable):
openssh-server-5.8p2-25.fc16.x86_64

How reproducible:
Always

Steps to Reproduce:
1. man moduli
2. search for "Sophie"
  
Actual results:
 4     Sophie Germain; (p+1)*2 is also prime.

Expected results:
 4     Sophie Germain; p*2+1 is also prime.

Thanks for the report. I've pushed the fix [1], but since it's minimal documentation change I'll push an update later with other fixes.
