Package tikz Error: I did not find the tikz library 'crypto.symbols' I'm trying to compile a LaTex script on Debian 10 and would like to include the package "crypto.symbols" via \usetikzlibrary{crypto.symbols} Unfortunately, I always end up with the following error message: Package tikz Error: I did not find the tikz library 'crypto.symbols'. I lookels.code.tex, but neither could be found in the current texmf trees.. \usetikzlibrary{crypto.symbols} Which additional package do I have to install to get this script to run?

You need the file `tikzlibrarycrypto.symbols.code.tex`. It does not appear to be in TeXlive or elsewhere in Debian. You can download a copy from IACR.

You also need anything that `tikzlibrarycrypto.symbols.code.tex` depends on. In addition to what is bundled with tikz, it needs `pgflibraryarrows.new.code.tex`.

Download these files and place them in your personal TeX package directory. By default, that's the `texmf` directory in your home directory. Inside this directory, the files need to be under `…/tex/generic` since they're TeX sources that can be used with any format.


mkdir -p ~/texmf/tex/generic/pgf/libraries
cd ~/texmf/tex/generic/pgf/libraries
wget
