- Most .pfx files are in PKCS12 format, not the obsolete PFX format described in this article.
PFX (Personal Information Exchange) is a cryptographic container format developed by Microsoft. It has been criticized for being complex and poorly-designed. I was replaced by a (somewhat improved?) successor format, PKCS12.
PFX is used for crypto keys, certificates, and other objects. Multiple objects may be stored in a single file.
