If you obtained a certificate and its private key in PEM or another format, you must convert it to PKCS#12 (PFX) format before you can import the certificate into a Windows certificate store on a View server. PKCS#12 (PFX) format is required if you use the Certificate Import wizard in the Windows certificate store. From PEM (pem, cer, crt) to PKCS#12 (p12, pfx) This is the console command that we can use to convert a PEM certificate file (.pem.cer or.crt extensions), together with its private key (.key extension), in a single PKCS#12 file (.p12 and.pfx extensions): openssl pkcs12 -export -in certificate.crt -inkey privatekey.key -out certificate.pfx. Oct 18, 2018 Converting PEM to PKCS7 – PKCS7 files can only contain certificates and certificate chains, never private keys. Openssl crl2pkcs7 -nocrl -certfile certificatename.pem -out certificatename.p7b -certfile CACert.cer Converting PKCS7 to PEM – Remember, this file will not include the keypair.
Openssl pkcs7 -printcerts -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. Aug 13, 2020 openssl pkcs7 -printcerts -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.
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 (.crt, .cer) files. To use the SSL Converter, just select your certificate file and its current type (it will try to detect the type from the file extension) and then select what type you want to convert the certificate to and click Convert Certificate. For more information about the different SSL certificate types and how you can convert certificates on your computer using OpenSSL, see below.
PEM Format
The PEM format is the most common format that Certificate Authorities issue certificates in. PEM certificates usually have extensions such as .pem, .crt, .cer, and .key. They are Base64 encoded ASCII files and contain '-----BEGIN CERTIFICATE-----' and '-----END CERTIFICATE-----' statements. Server certificates, intermediate certificates, and private keys can all be put into the PEM format.
Apache and other similar servers use PEM format certificates. Several PEM certificates, and even the private key, can be included in one file, one below the other, but most platforms, such as Apache, expect the certificates and private key to be in separate files.
DER Format
The DER format is simply a binary form of a certificate instead of the ASCII PEM format. It sometimes has a file extension of .der but it often has a file extension of .cer so the only way to tell the difference between a DER .cer file and a PEM .cer file is to open it in a text editor and look for the BEGIN/END statements. All types of certificates and private keys can be encoded in DER format. DER is typically used with Java platforms. The SSL Converter can only convert certificates to DER format. If you need to convert a private key to DER, please use the OpenSSL commands on this page.
PKCS#7/P7B Format
The PKCS#7 or P7B format is usually stored in Base64 ASCII format and has a file extension of .p7b or .p7c. P7B certificates contain '-----BEGIN PKCS7-----' and '-----END PKCS7-----' statements. A P7B file only contains certificates and chain certificates, not the private key. Several platforms support P7B files including Microsoft Windows and Java Tomcat.
PKCS#12/PFX Format
The PKCS#12 or PFX format is a binary format for storing the server certificate, any 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.
When converting a PFX file to PEM format, OpenSSL will put all the certificates and the private key into a single file. You will need to open the file in a text editor and copy each certificate and private key (including the BEGIN/END statements) to its own individual text file and save them as certificate.cer, CACert.cer, and privateKey.key respectively.
OpenSSL Commands to Convert SSL Certificates on Your Machine
It is highly recommended that you convert to and from .pfx files on your own machine using OpenSSL so you can keep the private key there. Use the following OpenSSL commands to convert SSL certificate to different formats on your own machine:
OpenSSL Convert PEM
Convert PEM to DER
Pem To Pkcs Test
Hot water burn.
openssl x509 -outform der -in certificate.pem -out certificate.der
Convert PEM to P7B
openssl crl2pkcs7 -nocrl -certfile certificate.cer -out certificate.p7b -certfile CACert.cer
Convert PEM to PFX
openssl pkcs12 -export -out certificate.pfx -inkey privateKey.key -in certificate.crt -certfile CACert.crt
OpenSSL Convert DER
Convert DER to PEM
openssl x509 -inform der -in certificate.cer -out certificate.pem
OpenSSL Convert P7B
Convert P7B to PEM
openssl pkcs7 -print_certs -in certificate.p7b -out certificate.cer
Convert P7B to PFX
openssl pkcs7 -print_certs -in certificate.p7b -out certificate.cer
openssl pkcs12 -export -in certificate.cer -inkey privateKey.key -out certificate.pfx -certfile CACert.cer
OpenSSL Convert PFX
Convert PFX to PEM
openssl pkcs12 -in certificate.pfx -out certificate.cer -nodes
Pem To Pkcs7
If you need to convert a Java Keystore file to a different format, it usually easier to create a new private key and certificates but it is possible to convert a Java Keystore to PEM format.
