How to rewrite PHP openssl_decrypt to Ruby?

Question

ruby

Dear PHP experts, please help me rewrite this code in Ruby using openssl.

openssl_decrypt($encrypted, "aes-256-cbc", $key, OPENSSL_RAW_DATA | OPENSSL_ZERO_PADDING, $iv)

$key is the text "abra-cadabra-123", 32 bytes long.
$iv is the text "abra-cadabra-123", 16 bytes long.
At the same time, openssl does not accept key, iv values ​​other than hex.
Are there any peculiarities in the PHP implementation?

Answer 1

In my case, besides

cipher = OpenSSL::Cipher::AES256.new(:CBC)
cipher.decrypt
cipher.key = "..."
cipher.iv  = "..."

it was required to add cipher.resetimmediately after processing the next block with cipher.update.
