Web27 de abr. de 2016 · AES supports three key lengths. They are 128, 192 and 256 bits long. You chose to use the 256 bit algorithm that operates in CBC mode. It's a correct choice. Now all you need is: key - 256 bits long initialization vector - 128 bits long You can generate them using the command I found here: openssl enc -aes-256-cbc -k secret -P -md sha1 For AES-128 that means Hash1 is the key and Hash2 is the IV. For AES-256, the key is Hash1+Hash2 (concatenated, not added) and Hash3 is the IV. You need to strip off the leading Salted___ header, then use the salt to compute the key and IV. Then you'll have the pieces to feed into EVP_DecryptInit_ex. granolithic tiles https://remax-regency.com
