Are there any secure openssl symmetric encryption routines that *don't* use a salt?
Is it secure to use a random-but-fixed salt (openssl enc -S salt)? "man enc" says "This option [-salt] should ALWAYS be used [...]" Reason I ask: I was using this command to backup files using compression/encryption: bzip2 -k -c original | openssl enc -bf -pass file:passfile > encfile and was surprised that doing this to identical files yielded different results. I then realized "openssl enc" randomly(?) chooses a salt if you don't supply one. I want my backups encrypted, but I also want identical files to encrypt identically.

We feel that resistance to new ideas and technology is unwise and ultimately futile. _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
