Subject: Fix some REALLY stupid typos in the fastreject RSA key generation.
X-Git-Tag: v1.0~1
X-Git-Url: https://git.rm.cloudns.org/?a=commitdiff_plain;h=ff1ce7e0336399c51e89a34ef9ad969a4d46b334;p=xonotic%2Fd0_blind_id.git

Fix some REALLY stupid typos in the fastreject RSA key generation.

This fixes crypto-keygen-standalone with a requested prefix.
