In cryptography, PKCS #12 defines an archive file format for storing many cryptography objects as a single file. It is commonly used to bundle a private key with its X.509 certificate or to bundle all the members of a chain of trust.

Defines the core behavior of a SafeBag value from the PKCS#12 specification and provides a base for derived classes. Pkcs12SafeContents: Represents a PKCS#12 SafeContents value. This class cannot be inherited. Pkcs12SafeContentsBag: Represents the SafeContentsBag from PKCS#12, a container whose contents are a PKCS#12 SafeContents value. PEM and PKCS#7 use Base ASCII (American Standard Code for Information Interchange) encoding. This is a popular standard for files that contain text. DER and PKCS#12 use binary encoding, a base 2 number system consisting only of zeros and ones. Because of different formats and encoding, SSL certificates have many file extensions. The PKCS #12 binary certificate package is a password-encrypted package that can contain nearly any type of data. In its common form, the PKCS #12 package is similar to a PKCS #7 certificate chain with a private key included. In this form, it is the only form of PKCS #12 package that RACF® supports.

Authenticode 6

An Authenticode X.509 certificate.

Cert 1

A single X.509 certificate.

Pfx 3

A PFX-formatted certificate. The Pfx value is identical to the Pkcs12 value.

Pkcs12 3

A PKCS #12-formatted certificate. The Pkcs12 value is identical to the Pfx value.

Pkcs7 5

A PKCS #7-formatted certificate.

SerializedCert 2

A single serialized X.509 certificate.

SerializedStore 4

A serialized store.

Unknown 0

An unknown X.509 certificate.


Content types Cert, Pkcs12, and SerializedCert can be exported as byte arrays. Therefore, all three formats are serialized certificates. SerializedCert differs from an exported Cert file in that it is created by using the CertSerializeCertificateStoreElement function, which serializes both the encoded certificate and its encoded properties. If you export the same X509Certificate object in both formats and view the resulting byte arrays, you will see that the two are different.

Applies to

You have a private key file in an openssl format and have received your SSL certificate. You'd like now to create a PKCS12 (or .pfx) to import your certificate in an other software?

Here is the procedure!

  • Find the private key file (xxx.key) (previously generated along with the CSR).
  • Download the .p7b file on your certificate status page ('See the certificate' button then 'See the format in PKCS7 format' and click the link next to the diskette).
  • a) Convert this file into a text one (PEM):

    On Windows, the OpenSSL command must contain the complete path, for example:
    c:openssl-win32binopenssl.exe ...)

  • b) Now create the pkcs12 file that will contain your private key and the certification chain:

    You will be asked to define an encryption password for the archive (it is mandatory to be able to import the file in IIS). You may also be asked for the private key password if there is one!

Pkcs12 Openssl

You can now use the file file final_result.p12 in any software that accepts pkcs12! For IIS, rename the file in .pfx, it will be easier.

Create Pkcs12

Alternatively, if you want to generate a PKCS12 from a certificate file (cer/pem), a certificate chain (generally pem or txt), and your private key, you need to use the following command:
