(PHP 4 >= 4.0.4, PHP 5)openssl_sign -- Generate signature

Description

bool openssl_sign (string data, string &signature, mixed priv_key_id [, int signature_alg])

Возвращает TRUE в случае успешного завершения или FALSE в случае возникновения ошибки.

If successful the signature is returned in

signature.

openssl_sign() computes a signature for the

specified data by using SHA1 for hashing

followed by encryption using the private key associated with

priv_key_id. Note that the data itself is

not encrypted.

Пример 1. openssl_sign() example <?php // $data is assumed to contain the data to be signed // fetch private key from file and ready it $fp = fopen("/src/openssl-0.9.6/demos/sign/key.pem", "r"); $priv_key = fread($fp, 8192); fclose($fp); $pkeyid = openssl_get_privatekey($priv_key); // compute signature openssl_sign($data, $signature, $pkeyid); // free the key from memory openssl_free_key($pkeyid); ?>
