 Oops, seems like it was a user error in my behalf after all:
 
 https://mail-index.netbsd.org/netbsd-users/2026/10/31/msg035138.html
 
 Perhaps it would be useful to improve the error message? Also, cgdconfig 
 -g happily produces an according config:
 
 $ cgdconfig -g -o ./testfile.cfg aes-cbc 512
 pkcs5_pbkdf2: calibrating iterations................. done
 $ cat testfile.cfg
 algorithm aes-cbc;
 iv-method encblkno1;
 keylength 512;
 verify_method none;
 keygen pkcs5_pbkdf2/sha1 {
          iterations 378453;
          salt AAAAgCymR3AKBAk7bnmdY+xNOp8=;
 };
 $
 
 ...which makes this a little harder to realize as an invalid config as a 
 user. Sorry, I hope this feedback is useful!
