For one of my VMs I forgot to note which of the initial password I had changed, so I wanted to check them.
Since I didn’t have a keyboard attached to the console and ssh wasn’t allowing root, I needed an alternative than actual login to test the passwords.
Luckily /etc/shadow, with getent and openssl came to the rescue.
Since getent varies per distribution, here is how it works on OpenSuSE:

A while ago, I had to fix some stuff in an application that would write – using a binary mechanism – UTF-8 and UTF-16 strings (part of it XML in various flavours) to the same byte stream without converting between the two encodings.
Some links that helped me investigate what was wrong, choose what encoding to use for storage and fix it:
TEncoding.UTF8.GetBytes: utf 8 – String to byte array in UTF-8? – Stack OverflowSysUtils.ByteLength() is not the nicest function, so use only for a quick-fix Delphi Unicode String Length in Bytes – Stack OverflowAnsiString, UnicodeString et al: String Types (Delphi) – RAD Studio–jeroen
