Google Authenticator is the only trusted and free implementation of RFC 4226 that I know of. It falls short in two aspects. First, it uses an 80-bit secret key instead of the suggested minimum 128-bits. Second, it uses SHA1 for the hashing algorithm instead of at least SHA2. Is there a free implementation that has at least a 128-bit secret key and better hash algorithm and also is as versatile as Google Authenticator, with applications across multiple platforms? 209.149.113.5 ( talk) 19:47, 8 August 2017 (UTC)
I accidentally mistyped "ls" as "ll" on my Ubuntu machine and was surprised to find that it's actually a valid command. Ubuntu comes standard with the following alias by default:
alias ll='ls -alF' alias la='ls -A' alias l='ls -CF'
Are these aliases standard across various Linux distributions? Are they available on the *BSD platforms as standard?
I wouldn't want to start memorizing them and relying on them unless they are fairly standard across most distros. Mũeller ( talk) 23:42, 8 August 2017 (UTC)
