SSL Certificate CSR Creation for Java Based Web Servers.

The encryption param of openssl genrsa command is used to specify which algorithm to use for encrypting your private key (using the password you specify). CSR (Certificate Signing Request) includes your public key and some additional public information to be included into certificate. CSR never includes a private key. Please help me to create AES 128 encrypted openssl certificate which can be used for Apache SSL configuration. I am able to create RSA/DSA keys with AES128 encryption using following command. # openssl genrsa -aes128 -out key.pem Is it possible to create AES 128 encrypted key without using RSA/DSA algorithms.

If you already have your SSL Certificate and just need to install it, see
SSL Certificate Installation :: Java Web Servers.

How to generate a CSR using Java Keytool

**NOTE: You must generate a new keystore through this process. If you try to install a new certificate to an old keystore your certificate will not work properly. Backup and remove any old keystores if necessary before beginning this process.

Recommended: Save yourself some time by using our new Java Keytool CSR Wizard to create your CSR with Keytool. Just fill in the details, click Generate, and paste your customized keytool command into your terminal.

If you prefer to roll your own keytool commands to generate your CSR, just follow our old instructions below:

Create a New Keystore

  1. You will be using the keytool command to create your new key-CSR pairing. Enter the following:

    keytool -genkey -alias server -keyalg RSA -keysize 2048 -keystore yourdomain.jks

    'Yourdomain' is the name of the domain you are securing. However, if you are ordering a Wildcard Certificate, do not include * in the beginning of the filename as this is not a valid filename character.

  2. You will be prompted for the DN information. Please note: when it asks for first and last name, this is not YOUR first and last name, but rather your domain name and extension(i.e., www.yourdomain.com). If you are ordering a Wildcard Certificate this must begin with *. (example: *.digicert.com)

  3. Confirm that the information is correct by entering 'y' or 'yes' when prompted. Next you will be asked for your password to confirm. Make sure to remember the password you choose.

Generate Your CSR with Your New keystore

  1. Next, use keytool to actually create the Certificate Signing Request. Enter the following:

    keytool -certreq -alias server -keyalg RSA -file yourdomain.csr -keystore yourdomain.jks

    Again, 'yourdomain' is the name of the domain you are securing. (without the * character if you are ordering a Wildcard Certificate).

  2. Enter the keystore password.

  3. Then the SSL Certificate CSR file is created. Open the CSR with a text editor, and copy and paste the text (including the BEGIN and END tags) into the DigiCert web order form.

  4. After you receive your SSL Certificate from DigiCert, you can install it.

Symmetic encryption

Openssl Aes Encryption

For symmetic encryption, you can use the following:

To encrypt:

To decrypt:

Asymmetric encryption

For Asymmetric encryption you must first generate your private key and extract the public key.

To encrypt:

To decrypt:

Encripting files

You can't directly encrypt a large file using rsautl. Instead, do the following:

  • Generate a key using openssl rand, e.g. openssl rand 32 -out keyfile.
  • Encrypt the key file using openssl rsautl.
  • Encrypt the data using openssl enc, using the generated key from step 1.
  • Package the encrypted key file with the encrypted data. The recipient will need to decrypt the key with their private key, then decrypt the data with the resulting key.

Ultimate solution for safe and high secured encode anyone file in OpenSSL and command-line:

Encrypt a file

Encrypt binary file:

Encrypt text file:

What is what:

  • smime — ssl command for S/MIME utility (smime(1)).
  • -encrypt — chosen method for file process.
  • -binary — use safe file process. Normally the input message is converted to 'canonical' format as required by the S/MIME specification, this switch disable it. It is necessary for all binary files (like a images, sounds, ZIP archives).
  • -aes-256-cbc — chosen cipher AES in 256 bit for encryption (strong). If not specified 40 bit RC2 is used (very weak). (Supported ciphers).
  • -in plainfile.zip — input file name.
  • -out encrypted.zip.enc — output file name.
  • -outform DER — encode output file as binary. If is not specified, file is encoded by base64 and file size will be increased by 30%.
  • yourSslCertificate.pem — file name of your certificate's. That should be in PEM format.

That command can very effectively a strongly encrypt any file regardless of its size or format.

Decrypt a file

Decrypt binary file:

For text files:

What is what:

Openssl Encryption

  • -inform DER — same as -outform above.
  • -inkey private.key — file name of your private key. That should be in PEM format and can be encrypted by password.
  • -passin pass:your_password — (optional) your password for private key encrypt.
