Google have recently announced that they are going to start reporting that SSL certificates that are signed with a SHA-1 Hash will be treated as having a lower security than those signed with newer, higher strength hashes such as SHA-256 or SHA-512.

May 15, 2018 This video tutorial will show you how to use the openssl command line to encrypt and decrypt a file using a public key. We will first generate a private key then extract the public key from this. Generate an OpenSSL Certificate Request with SHA256 Signature Google have recently announced that they are going to start reporting that SSL certificates that are signed with a SHA-1 Hash will be treated as having a lower security than those signed with newer, higher. I am using OpenSSL libs and programming in C for encrypting data in aes-cbc-128. I am given any input binary data and I have to encrypt this. Anytime upgrade key generator for vista to windows 7. I learn that Java has a CipherParameters interface to set IV and KeyParameters too. Is there a way to generate IV and a key using openSSL?

Tutorial: AES Encryption and Decryption with OpenSSL. In EclipseSource News. Key stretching is performed to create a long, fixed-length key from a short, variable length password. Key stretching uses a key-derivation function. Command line OpenSSL uses a rather simplistic method for computing the cryptographic key from a. My goal was to create a private key and to encrypt it with a strong cipher. That key would be used as a root certificate for an internal Certification Authority. Creating a private key with OpenSSL and encrypting it with AES GCM. Ask Question Asked 5 years, 1 month ago. The changelog of openssl for ubuntu states for a prior version. See KEY GENERATION OPTIONS below for more details.genparam generate a set of parameters instead of a private key. If used this option must precede and -algorithm, -paramfile or -pkeyopt options.paramfile filename Some public key algorithms generate a private key based on a set of parameters. They can be supplied using this option.

Technically at the moment there isn’t anything really wrong with the SHA-1 hash function, but it is now quite old and is starting to show potential cracks. Hence the reason that the security industry is advising to move to something better. In this case SHA-256.

1. Generate a SSL Key File

Firstly you will need to generate a key file. The example below will generate a 2048 bit key file with a SHA-256 signature. /a-primary-key-especially-an-auto-generated-surrogate-key-is-sufficient.html.

If you want extra security you could increase the bit lengths.

** Please note that both these examples will not add a password to the key file. To do that you will need to add -aes256 to the command.

2. Create a Certificate Signing Request (CSR)

Openssl

This step will create the actually request file that you will submit to the Certificate Authority (CA) of your choice.

You can check that your Certificate Signing Request (CSR) has the correct signature by running the following.

It should display the following if the signature is correct.

3. Install the Certificate (CRT)

This step is very dependant of the software you use and I won’t really cover. All I will say is that these certificates are supported by a multitude of software, including Apache HTTPD and NGINX.

4. Test your installed Certificate

This step is extremely important and will show you any security problems with your SSL configuration.

Qualys have a free hosted service that tests the SSL configuration of Internet facing web servers for SSL issues. The sites tested are rated from A to F, and a report is generated. This report is really useful for tuning your SSL configuration.

The SSL Labs tests are regularly updated when new issues are discovered. This means that if your server is rated as A today, next week it maybe rated as C.
