:''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.
