How encrypt with vector - omid_student - 01-28-2020 Hi I use encryption library with AES cipher I need encrypt my data with vector but this library dont have any field or method about vector Please help me RE: How encrypt with vector - InsiteFX - 01-29-2020 What library are you using? OpenSSL can use a vector IV. RE: How encrypt with vector - omid_student - 01-29-2020 (01-29-2020, 03:29 AM)InsiteFX Wrote: What library are you using? OpenSSL can use a vector IV.Encryption library I use openSSL but this library dont have any properties or method for vector RE: How encrypt with vector - InsiteFX - 01-29-2020 OpenSSL creates the IV vector like this: iv = initialization vector PHP Code: $iv = openssl_random_pseudo_bytes(openssl_cipher_iv_length('AES-256-CBC')); openssl_cipher_iv_length RE: How encrypt with vector - omid_student - 01-30-2020 (01-29-2020, 09:08 AM)InsiteFX Wrote: OpenSSL creates the IV vector like this:I know it but how do i use it in codeigniter encryption library? RE: How encrypt with vector - InsiteFX - 01-30-2020 Make sure that you are using the library version it has OpenSSL driver. From viewing the library they are doing the vector using the key. PHP Code: $key = openssl_random_pseudo_bytes($length, $is_secure); As you can see above. The vector is from what I read just the length of the key.

Doesn't the vector contain a series of characters? Do you can give me sample for use vector? Thanks RE: How encrypt with vector - InsiteFX - 01-30-2020 This is how it works from php.net openssl_encrypt RE: How encrypt with vector - omid_student - 01-30-2020 (01-30-2020, 01:03 PM)InsiteFX Wrote: This is how it works from php.netThanks |
