.PFX
PKCS #12 Certificate File
A PFX file is an encrypted security format that typically stores one or more password-protected digital certificates and private keys for authenticating a person, application, or device (including computers and web servers). PFX files were initially saved in the Personal Information Exchange (PFX) format Microsoft released in 1996 but are now saved in the PKCS #12 format, which succeeded and extended PFX (people often use the format names interchangeably).
