Hi all. I'm on OpenSMTPD 7.0.0 and am trying out queue encryption.
Almost any key that I try errors with "smtpd: crypto_setup:invalid key for queue encryption". If I use "openssl rand -hex 16" (which I found in an example on Gilles's site - https://poolp.org/posts/2013-04-26/opensmtpd-table_proc-queue_proc-crypto-queue-and-other-stuff/) it always seems to work, but if I increase the number it often fails. So, mostly out of curiosity, I was wondering what are the limitations for a valid queue encryption key? As a side note, if I check my config (smtpd -n) while queue encryption is set to "-" or "stdin" I get the same error message (although the server still seems to work). Is that a bug? Josey
