Many printers, especially those used in businesses, support IPP over HTTPS. If you have access to the printer's control panel, you can enable HTTPS and install a certificate that you trust. On your computer, set up a printer manually and specify https://printer-domain or printer-domain:443 as the printer's address, depending on what operating system you are ...

There's no question that this extra MD5 layer is better than just using the original password. The question is whether you'd be better off using a Password Manager which simply generates random passwords and stores them in encrypted form. I do see the elegance of your solution over a Password Manager. Since the final password is derived, not stored, then ...

There are many good algorithms for various purposes, and virtually any of them, improperly applied, can result in a disastrously broken cryptosystem. This is one of the reasons people offer advice like "use libsodium" because libraries like ...

There's a general principle that a hash function like MD5 cannot add entropy - which means that if this method was a tool, a piece of software that people attempting to discover the password became aware of, it would simply be another rule, another step in their attempts, and would only marginally slow them down. However, if this was a method that Bob ...

The presence of some security controls does not make a system secure. Yes I think you have identified a valid problem but that organization could still truthfully say the confidential data was never sent in an unencrypted fashion. Unfortunately there are many vendors touting things as being secure because they either have some security controls or because ...
