PHP SDK users don't need to convert their PEM certificate to the.p12 format. Open a command prompt and navigate to the directory that contains the certkeypem.txt file. Execute the following OpenSSL command to create a PKCS12 (.p12) file: openssl pkcs12 -export -inkey certkeypem.txt -in certkeypem.txt -out certkey.p12.
Many browsers, such as FireFox and Internet Explorer, require private keys and certificates in PKCS12 format for installation. In order to install client and intermediate certificates into these browsers, you will first have to convert them from PEM format to PKCS12 format. (Note: if you created your certificate using IIS as explained in the previous section, then your certificate is already in PKCS12 format; it can be installed directly into a browser without conversion.)
Like PEM format, PKCS12 format supports having all your certificates and your private key in one file. If you created the file
clientprivcert.pem (containing the client certificate, the private key, and any intermediate certificates), then converting the file to PKCS12 is simple:
openssl pkcs12 -export -in clientprivcert.pem -out clientprivcert.pfx
The DER certificate format, which stands for “distinguished encoding rules, is a binary form of PEM-formatted certificates. DER format can include certificates and private keys of all types, however, they mostly use.cer and.der extensions. The DER certificate format is most commonly used in Java-based platforms. PFX/P12/PKCS#12 Format. SSL Converter is a free online tool to convert SSL certificates from PEM format to PKCS#12, PKCS#7 or DER format. ← Click the tab to choose the target format. Description While USM Appliance requires PEM Formatted (ASCII PEM formatted X.509) certificates for uploading to the Appliance, some registrars may only provide certificates in PKCS12 format, which is not compatible. In this scenario, the PKCS12 certficates can be uploaded to the Appliance, and then converted through jailbreak.
The resulting file,
clientprivcert.pfx, can now be installed into all client browsers that will be accessing the cluster that requires a client certificate.
Refer to the Microsoft, Mozilla, Google, and Apple for documentation for instructions on installing certificates on IE, Firefox, Chrome and Safari, respectively.
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:
- 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!
Openssl Pem To Pkcs12
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:
