Certifiable is an open source command line program for Windows which generates code to assign a SSL Certificate PEM to a variable.

The following languages are supported for code generation: C++, Python, and VB.net. If you would like another programming language added, please just open an issue including an example of what a statement would look like in that language.

You are welcome to download and use Certifiable on as many computers as you would like.

A downloadable signed executable portable copy of the program for Windows (x64) is available from here.

Certifiable does not need to be installed, rather download file (above) and run it.

From the Windows command line enter:

certifiable api.pushbullet.com -n 2 -c

the following response is returned:

From the command prompt just type "certifiable ?" (without the quotes) to see the help as mostly reproduced below:

certifiable [ host (-p n) (-d) (-n n) (-g x (progmem)) (-v x) (-c) (-w x) (-o) (-f) ] | [ ] | [ ? ]

host         the host name or IP address from which to get the certificate(s)
for example: google.com, www.google.com, 142.251.41.14
a host value is required in all cases other than displaying this help information

Options:

-p n        the host's port number
               for example: -p 8096
               if not used a port number of 443 will be assumed

-d           display the host's certificate(s) with unique number for each
               if neither -c or -o options are used, the -d option will be assumed

-f            by default future dated certificates are excluded
               if -f is used, then future dated certificates will be included
               note: expired certificates are always excluded

-n n       in many cases a host will have multiple certificates
               -n indicates a specific certificate should be used for code generation, the second n specifies which one
               for example, -n 3
               indicates only the 3rd certificate should be used for code generation
               if not used, code for all certificates will be generation

-g x         used to specifying the language in which the code will be generated
               supported languages are: c++, python, and vb.net
               for example: -g vb.net
               Additionally, c++ may be followed by the option progmem
               if c++ is followed by progmem the generated code will store the certificate in program memory
               (flash memory) rather than in RAM (SRAM)
               for example: -g c++ progmem
               if not used, the c++ will be assumed

-v x         the variable name to be used in the output file
               for example: -v server_root_cert
               if not used, a variable name based on the host name / IP address will be generated

-c           the generated code will be copied to the clipboard

-w x        the generated code will be written to the specified (path and) file name
               for example, -w c:\temp\certificate.h
               the output path name is optional, if omitted the output file will be written to the current working directory
               for example, -w certificate.h
               if the path is specified but does not exist, it will be created

-o           if the -w option is used and the specified file already exists
               the user will be prompted to overwrite the file unless the -o options is used
               in which case the existing file will be automatically overwritten
               for example, -w c:\temp\certificate.h -o

Certifiable used with no arguments, or with '?' displays this help

Final notes on usage:
  the -d option does not generate code, rather simply displays available information
  code will only be generated if the -c or -w options are used

Certifiable is built upon the .net framework 8
