What is CertificateInfo?
CertificateInfo is a Total Commander content plugin (WDX) that provides various pieces of information about certificate files like CER, CRT, DER, PEM, P7B, PFX, P12 and SST. It supports binary encoded files as well as Base64 encoded ones.
It can also be used as a packer plugin (WCX) with which it's possible to extract single certificates from certificate files and to convert between binary and Base64 formats.
