This command uses AES 128 only to protect the RSA key pair with a passphrase, just in case an unauthorized person can get the key file. When your Apache server starts up, it must decrypt the key in memory to use it.
- RandomKeygen is a free mobile-friendly tool that offers randomly generated keys and passwords you can use to secure any application, service or device. KEY RandomKeygen - The Secure Password & Keygen Generator.
- Use the OpenSSL command-line tool, which is included with the Master Data Engine, to generate AES 128-, 192-, or 256-bit keys. The madpwd3 utility is used to create the password.
Symmetic 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: Windows 8 upgrade key generator.
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.

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

What is what:
-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.
