P7b Files

P7b

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.
For information on OpenSSL please visit: www.openssl.org
Note: OpenSSL is an open source tool that is not provided or supported by Thawte
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.

The p7b file extension is used for certification purposes used in internet traffic communication. Security file that stores secure certificates used to authenticate a person or device, such as a computer or Web server. Help how to open: It is not possible to open p7b extension files. This list was quite long, as the.p7b file holded several certificates. The next step was to copy all fragments between -BEGIN CERTIFICATE- and -END CERTIFICATE- and store them in different files with a.pem 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
P7b


Convert PEM to P7B

File

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.

P7b Files
openssl crl2pkcs7 -nocrl -certfile certificatename.pem -out certificatename.p7b -certfile CACert.cer


Convert PKCS7 to PEM

P7b Files
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 pkcs8 -in certificatename.pem -topk8 -nocrypt -out certificatename.pk8


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

Open P7b Files

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

P7B File Summary

File Extension P7B has only one distinct file type (PKCS #7 Certificate File format) and is mostly associated with Microsoft Windows (Microsoft Corporation) and four other software programs. The majority of P7B files are considered Web Files.

Windows, Mac, and Linux operating systems can be used to view P7B files. Both desktop and mobile devices enable you to view and (sometimes) edit these files, depending on the software used. P7B files have a 'Low' Popularity Rating; this means that they are not present on most devices.

Although there is a lot more to know about P7B files, those are the most important details of these types of files. If you are having trouble opening these files, or would like more detailed information, please see our comprehensive information below.
