OpenSSL Commands and SSL Keytool List

OpenSSL is an open-source implementation of SSL/TLS protocols and is considered to be one of the most versatile SSL tools. It’s a library written in C programming language that implements the basic cryptographic functions. OpenSSL has different versions for most Unix-like operating systems, which include Mac OC X, Linux, and Microsoft Windows etc.

Open SSL is normally used to generate a Certificate Signing Request (CSR) and private key for different platforms. However, it also has several different functions, which can be listed as follows. It is used to:

  • View details about a CSR or a certificate
  • Compare MD5 hash of a certificate and private key to ensure they match
  • Verify proper installation of the certificate on a website
  • Convert the certificate format

Most of the functions mentioned below can also be performed without involving OpenSSL by using these convenient SSL tools. Here, we have put together few of the most common OpenSSL commands.

General OpenSSL Commands

  1. Lastly, this process can be leveraged to create and import a wildcard certificate into the iDRAC. From a security stand point, the use of wildcard is not a best practices; however, the process used to create any external certificate can also be leveraged for a wildcard certificate. Binopenssl.exe genrsa -aes256 -out keys/ca.key 2048.
  2. May 17, 2013 Create a self-signed wildcard certificate using OpenSSL on Windows 2013-05-17 1 Comment I needed to create a certificate to enable SSL on some of our internal sites and got a bit frustrated that my self signed cert kept on showing the warning about it not being trusted.
  3. Mar 12, 2020 Use the OpenSSL command-line tool, which is included with InfoSphere MDM, to generate AES 128-, 192-, or 256-bit keys. The madpwd3 utility is used to create the password. Generating AES keys and password.

These are the set of commands that allow the users to generate CSRs, Certificates, Private Keys and many other miscellaneous tasks. Here, we have listed few such commands:

(1) Generate a Certificate Signing Request (CSR) and new private key

The command I'm using to generate the key is: $ ope. Stack Exchange Network Stack Exchange network consists of 175 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. Oct 16, 2019  For Asymmetric encryption you must first generate your private key and extract the public key. Openssl genrsa -aes256 -out private.key 8912 openssl rsa -in private.key -pubout -out public.key To encrypt: openssl rsautl -encrypt -pubin -inkey public.key -in plaintext.txt -out encrypted.txt To decrypt: openssl rsautl -decrypt -inkey private.key -in encrypted.txt -out plaintext.txt Encripting files.

(2) Generate a self-signed certificate

(3) Create CSR based on an existing private key

(4) Create CSR based on an existing certificate

(5) Passphrase removal from a private key

SSL Check Commands

These commands are very helpful if the user wants to check the information within an SSL certificate, a Private Key, and CSR. Few online tools can also help you check CSRs and check SSL certificates.

(1) Certificate Signing Request (CSR)

(2) Private Key

(3) SSL Certificate

(4) PKCS#12 File (.pfx or .p12)

Convert Commands

As per the title, these commands help convert the certificates and keys into different formats to impart them the compatibility with specific servers types. For example, a PEM file, compatible with Apache server, can be converted to PFX (PKCS#12), after which it would be possible for it to work with Tomcat or IIS. However, you can also use the SSL Converter to change the format, without having to involve OpenSSL.

(1) Convert DER Files (.crt, .cer, .der) to PEM

(2) Convert PEM to DER

(3) Convert PKCS #12 File (.pfx, .p12) Containing a Private Key and Certificate to PEM

To output only the private key, users can add –nocerts or –nokeys to output only the certificates.

(4) Convert PEM Certificate (File and a Private Key) to PKCS # 12 (.pfx #12)

Debugging Using OpenSSL Commands

If there are error messages popping up about your private key not matching the certificate or that the newly-installed certificate is not trusted, you can rely on one of the comments mentioned below. You can also use the SSL certificate checker tool for verifying the correct installation of an SSL certificate.

(1) Check SSL Connection (All certificates, including Intermediates, are to be displayed)

(2) Check MD5 Hash of Public Key

This is to ensure that the public key matches with the CSR or the private key.

SSL Keytool List

Java Keytool is a key and certificate management utility that allows the users to cache the certificate and manage their own private or public key pairs and certificates. Java Keytool stores all the keys and certificates in a ‘Keystore’, which is, by default, implemented as a file. It contains private keys and certificates that are essential for establishing the reliability of the primary certificate and completing a chain of trust.

Every certificate in Java Keystore has a unique pseudonym/alias. For creating a ‘Java Keystore’, you need to first create the .jks file containing only the private key in the beginning. After that, you need to generate a Certificate Signing Request (CSR) and generate a certificate from it. After this, import the certificate to the Keystore including any root certificates.

The ‘Java Keytool’ basically contains several other functions that help the users export a certificate or to view the certificate details or the list of certificates in Keystore.

Here are few important Java Keytool commands:

For Creating and Importing

Free

These Keytool commands allow users to create a new Java Keytool keysKeystore, generate a Certificate Signing Request (CSR) and import certificates. Before you import the primary certificate for your domain, you need to first import any root or intermediate certificates.

(1) Import a root or intermediate CA certificate to an existing Java keystore

(2) Import a signed primary certificate to an existing Java keystore

(3) Generate a keystore and self-signed certificate

(4) Generate Key Pair & Java Keystore

(5) Generate CSR for existing Java Keystore

For Checking

Users can check the information within a certificate or Java keystore by using the following commands:

(1) Check an individual certificate

(2) Check certificates in Java keystore

(3) Check specific keystore entry using an alias

Other Java Keytool Commands

(1) Delete a certificate from Java Keystore keystore

(2) Change the password in Java keystore / Change a Java keystore password

(3) Export certificate from Java keystore

(4) List the trusted CA Certificate

(5) Import new CA into Trusted Certs
