Below is all the information we have available on file about the .crt (crt) file type.
Also known as an Internet security certificate file because it is the format of the security certificate used by secure web sites. Web browsers will automatically recognise .crt files as certificate files, so the user is not normally aware of them.
Where this is available we would like to include file format information on .crt files, as well as information on how to view or open files of type .crt. If you know of any information which we have missed then please let us know.
