Sometimes, you might want to convert your.p12 certificate file into.pem file (Personal Information Exchange), so that it can be used in grid computing environments or even in a Netscaler gateway. This tutorial will explain how to convert PFX file to PEM using Win32 OpenSSL utility on Windows operating system. Nov 20, 2018 p12证书转pem证书 p12证书转Pem. 为什么能转?很重要 p12 里面包含 证书 和 私钥 pem 里面也可以包含 证书和 私钥 所以只是格式(p12是二进制, pem是Ascii)不同, 本质是一样的.

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.

A PKCS #12 file may be encrypted and signed. The internal storage containers, called 'SafeBags', may also be encrypted and signed. A few SafeBags are predefined to store certificates, private keys and CRLs. Another SafeBag is provided to store any other data at individual implementer's choice.[1][2]

PKCS #12 is one of the family of standards called Public-Key Cryptography Standards (PKCS) published by RSA Laboratories.

The filename extension for PKCS #12 files is .p12 or .pfx.[3]

These files can be created, parsed and read out with the OpenSSLpkcs12 command.[4]

Relationship to PFX file format[edit]

PKCS #12 is the successor to Microsoft's 'PFX';[5]however, the terms 'PKCS #12 file' and 'PFX file' are sometimes used interchangeably.[3][4][6]

The PFX format has been criticised for being one of the most complex cryptographic protocols.[6]

Normal usage[edit]

The full PKCS #12 standard is very complex. It enables buckets of complex objects such as PKCS #8 structures, nested deeply. But in practice it is normally used to store just one private key and its associated certificate chain.

PKCS #12 files are usually created using OpenSSL, which only supports a single private key from the command line interface. The Java keytool can be used to create multiple 'entries' since Java 8, but that may be incompatible with many other systems. As of Java 9, PKCS #12 is the default keystore format.[7][8]

A simpler, alternative format to PKCS #12 is PEM which just lists the certificates and possibly private keys as Base 64 strings in a text file.

GnuTLS's certtool may also be used to create PKCS #12 files including certificates, keys, and CA certificates via --to-p12. However, beware that for interchangeability with other software, if the sources are in PEM Base64 text, then --outder should also be used.

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!

Pem P12 Crt

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.

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:
