On the whole, we can differentiate the following certificate file formats: In this article we will talk about the file formats which differ based on encoding rules. In fact the certificates we provide are issued in x.509 format which is the version of ASN.1 file encoding standard.
In order to convert the certificates from one format to another, you can use OpenSSL package generally available on Linux machines. p12) openssl pkcs12 -export -out certificate.pfx -inkey privateKey.key -in certificate.crt -certfile CACert.How to convert certificates into different formats using OpenSSLÄifferent servers and control panels may require SSL certificates in different file formats.
Openssl req -noout -modulus -in CSR.csr | openssl md5 Openssl rsa -noout -modulus -in privateKey.key | openssl md5 Check an MD5 hash of the public key to ensure that it matches with what is in a CSR or private key openssl x509 -noout -modulus -in certificate.crt | openssl md5.If you are receiving an error that the private doesn't match the certificate or that a certificate that you installed to a site is not trusted, try one of these commands. p12) openssl pkcs12 -info -in keyStore.p12 Check a certificate openssl x509 -in certificate.crt -text -noout.Check a private key openssl rsa -in privateKey.key -check.Check a Certificate Signing Request (CSR) openssl req -text -noout -verify -in CSR.csr.If you need to check the information within a Certificate, CSR or Private Key, use these commands. Remove a passphrase from a private key openssl rsa -in privateKey.pem -out newPrivateKey.pem.Generate a certificate signing request based on an existing certificate openssl x509 -x509toreq -in certificate.crt -out CSR.csr -signkey privateKey.key.Generate a certificate signing request (CSR) for an existing private key openssl req -out CSR.csr -key privateKey.key -new.Generate a self-signed certificate openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout privateKey.key -out certificate.crt.Generate a new private key and Certificate Signing Request openssl req -out CSR.csr -new -newkey rsa:2048 -nodes -keyout privateKey.key.These commands allow you to generate CSRs, Certificates, Private Keys and do other miscellaneous tasks.
