Pem To P7b

I have received a certificate in.p7b format. First, I converted it into.pem format. Then, I imported it into Firefox (or your browser). After that, I could access my application using that certificate. Now, in order to convert a.p7b into.pem do as follows. Openssl pkcs7 -inform der -in yourCert.p7b -printcerts -out yourCert.pem Hope this. Convert PEM to P7B Note: The PKCS#7 or P7B format is stored in Base64 ASCII format and has a file extension of.p7b or.p7c. A P7B file only contains certificates and chain certificates (Intermediate CAs), not the private key. The most common platforms that support P7B files are Microsoft Windows and Java Tomcat. DER a binary form of PEM. It has extension.der or.cer. DER is typically used with Java platforms. Convert DER to PEM. Openssl x509 -inform der -in certificate.cer -out certificate.pem. CONVERT FROM PKCS#7 OR P7B FORMAT. P7B formatted file is usually stored in Base64 format and has extension.p7b or.p7c. Use this SSL Converter to convert SSL certificates to and from different formats such as pem, der, p7b, and pfx.Different platforms and devices require SSL certificates to be converted to different formats. For example, a Windows server exports and imports.pfx files while an Apache server uses individual PEM.

Solution

If your server/device requires a different certificate format other than Base64 encoded X.509, a third party tool such as OpenSSL can be used to convert the certificates into the appropriate format.

Some common conversion commands are listed below:

Note: The PEM format is the most common format used for certificates. Extensions used for PEM certificates are cer, crt, and pem. They are Base64 encoded ASCII files. The DER format is the binary form of the certificate. DER formatted certificates do not contain the 'BEGIN CERTIFICATE/END CERTIFICATE' statements. DER formatted certificates most often use the '.der' extension.


Convert x509 to PEM

openssl x509 -in certificatename.cer -outform PEM -out certificatename.pem


Convert PEM to DER

openssl x509 -outform der -in certificatename.pem -out certificatename.der


Convert DER to PEM

openssl x509 -inform der -in certificatename.der -out certificatename.pem


Convert PEM to P7B

Note: The PKCS#7 or P7B format is stored in Base64 ASCII format and has a file extension of .p7b or .p7c.
A P7B file only contains certificates and chain certificates (Intermediate CAs), not the private key. The most common platforms that support P7B files are Microsoft Windows and Java Tomcat.

openssl crl2pkcs7 -nocrl -certfile certificatename.pem -out certificatename.p7b -certfile CACert.cer


Convert PKCS7 to PEM

openssl pkcs7 -print_certs -in certificatename.p7b -out certificatename.pem


Convert pfx to PEM

Note: The PKCS#12 or PFX format is a binary format for storing the server certificate, intermediate certificates, and the private key in one encryptable file. PFX files usually have extensions such as .pfx and .p12. PFX files are typically used on Windows machines to import and export certificates and private keys.

openssl pkcs12 -in certificatename.pfx -out certificatename.pem


Convert PFX to PKCS#8
Note: This requires 2 commands
STEP 1:Convert PFX to PEM

openssl pkcs12 -in certificatename.pfx -nocerts -nodes -out certificatename.pem


STEP 2:Convert PEM to PKCS8

Openssl Pfx To Pem

openSSL pkcs8 -in certificatename.pem -topk8 -nocrypt -out certificatename.pk8


Convert P7B to PFX
Note: This requires 2 commands
STEP 1: Convert P7B to CER

openssl pkcs7 -print_certs -in certificatename.p7b -out certificatename.cer


STEP 2: Convert CER and Private Key to PFX

openssl pkcs12 -export -in certificatename.cer -inkey privateKey.key -out certificatename.pfx -certfile cacert.cer

OpenSSL is a robust, commercial-grade, and full-featured toolkit for the Transport Layer Security (TLS) and Secure Sockets Layer (SSL) protocols. It is also a general-purpose cryptography library.

OpenSSL does not distribute code in binary form. However, you can download it from other websites. Visit wiki.openssl.org, select and download OpenSSL for your platform. For example, click on the https://slproweb.com/products/Win32OpenSSL.html link to download the installer for Windows. You can download the light or full version, as shown below.

Click on the installer and finish the installation wizard. After installation, go to C:OpenSSL-Win32bin and double click on openssl.exe to start working with OpenSSL. This will open a command prompt on Windows, as shown below.

OpenSSL Commands to Convert Certificate Formats

If you have got certificate files from the CA which are not supported on your web server, then you can convert your certificate files into the format your web server or hosting provider requires using OpenSSL commands.

To know about all the commands, apply the help command.

Openssl> help

To get help on a particular command, use -help after a command.

Openssl> pkcs12 -help

The following are main commands to convert certificate file formats.
