note 123361 added to function.openssl-encrypt

Hi, I have a module in Go that encrypts emails with AES-256-CBC. I want to decrypt this in PHP. The PHP module uses openssl_encrypt. The ciphertext generated by Go module fails to decrypt by the PHP module. Both use the exact same IV and KEY. Can someone tell me what am I doing wrong??
