From: jsing Date: Sat, 31 Aug 2024 15:39:33 +0000 (+0000) Subject: Merge fcrypt_b.c into fcrypt.c. X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=76b4b18fa2c7545d6f8cf3db1baea206b6747a22;p=openbsd Merge fcrypt_b.c into fcrypt.c. There is no need for these to be separate (presumably done due to assembly implementations, even though there are #ifdef as well).
