Use openssl_random_pseudo_bytes (most preferably with the second parameter set to an existing variable, which you should then test that it was set to TRUE). This will generate IVs with appropriate randomness characteristics. OpenSSL - Cryptography and SSL/TLS Toolkit We’ll walk through the following steps: Generate an AES key plus Initialization vector (iv) with openssl and how to encode/decode a file with the generated key/iv pair So, OpenSSL is padding keys and IVs with zeroes until they meet the expected size. Note that if -aes-192-cbc is used instead of -aes-256-cbc, decryption will fail, because OpenSSL will pad it with fewer zeroes and so the key will be different. OpenSSL Key and IV Padding OpenSSL is an omnipresent tool when it comes to encryption, but we're used to native Java implementations of cryptographic primitives. -iv IV The actual IV to use: this must be represented as a string comprised only of hex digits.

The basic command to use is openssl enc plus some options: -P — Print out the salt, key and IV used, then exit -k or -pass pass: — to specify the password to use -aes-256-cbc — the cipher name If you are using this for use in one of the open ssl methods, you can use the function openssl_cipher_iv_length(method) to get the correct length for the method used. The second parameter, &crypto_strong, allows you to pass in a boolean variable that will be set to true or false depending on whether the algorithm used was cryptographically secure. Binaries and Engines. The OpenSSL project does not distribute any code in binary form, and does not officially recommend any specific binary distributions.
