For symmetic encryption, you can use the following:
- How to generate a AES-256 CBC key/iv that can be shared as a string? Ask Question Asked 3 years, 5 months ago. Active 3 years, 5 months ago. You use a key generator, and if not available, a random number generator to generate a key of the correct size, in this case 32 bytes. You can feed that to the cipher implementation.
- The AES algorithm has a 128-bit block size, regardless of whether you key length is 256, 192 or 128 bits. When a symmetric cipher mode requires an IV, the length of the IV.
To encrypt:
To decrypt:
To decrypt the output of an AES encryption (aes-256-cbc) we will use the OpenSSL C API. Unlike the command line, each step must be explicitly performed with the API. There are four steps involved when decrypting: 1) Decoding the input (from Base64), 2) extracting the Salt, 3) creating the key (key-stretching) using the password and the Salt, and 4) performing the AES decryption.

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

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:

Aes 256 Cbc
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.
Aes 256 Iv
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:
-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.
