Common OpenSSL Commands with Keys and Certificates. Generate RSA private key with certificate in a single command openssl req -x509 -newkey rsa:4096 -sha256 -keyout example.key -out example.crt -subj '/CN=example.com' -days 3650 -passout pass:foobar Generate Certificate Signing Request (CSR) from private key with passphrase. Generate a self-signed certificate that is valid for a year with sha256 hash. Openssl x509 -req -sha256 -days 365 -in csr.pem -signkey private.pem -out certificate.pem. Use the opensslx509certificate resource to generate signed or self-signed, PEM-formatted x509 certificates. If no existing key is specified, the resource will automatically generate a passwordless key with the certificate. If a CA private key and certificate are provided, the.

OpenSSL provides read different type of certificate and encoding formats. OpenSSL supports certificate formats like RSA, X509, PCKS12 etc. We will look how to read these certificate formats with OpenSSL.

Openssl Generate X509 Certificate From Private Key Code

RSA is popular format use to create asymmetric key pairs those named public and private key. We can use rsa verb to read RSA private key with the following command.

X509 Certificate Private Key

We can see that the first line of command output provides RSA key ok

Another case reading certificate with OpenSSL is reading and printing X509 certificates to the terminal. We will use x509 version with the following command.

X509 certificates also holds information about the purpose of the cerficate. This will be beneficial while using certificate to learn the creation aim of the certificate. We can print certificate purpose with the -purpose command like below.

Openssl X509 Text

We can read and print web sites HTTPS certificates with the s_client verb which is explained in this tutorial. We can print the SSL/TLS X509 certificate with the following command.

Openssl Create Ca Certificate And Key

We can also read and print PKCS12 files which can be used store keys and related information. We will use pkcs12 verb like below.

Certificate signing requests are used to create required request in order to sign our certificate from certificate authority. After creating a Certificate Signing Request we should check the CSR with the following command where we can see all information provided by CSR.
