(PHP ActiveX) RSA Signature SHA256withRSA, iso-8859-1, base64See more RSA ExamplesRSA sign the iso-8859-1 byte representation of a string with SHA256withRSA, and return the signature in the base64 encoding.
<?php // This example requires the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. // This example will duplicate the following Java code: // // Signature sign = Signature.getInstance("SHA256withRSA"); // sign.initSign(privateKey); // sign.update(original.getBytes(Charset.forName("ISO-8859-1"))); // // ... // byte[] resultado = sign.sign(); // sello = encodeByteArrayToBase64(resultado); // // Load an RSA private key for signing. // You can load any format file. This example loads a .pem, but you can provide path to any type of file holding a private key. // For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.PrivateKey') $privKey = new COM("Chilkat.PrivateKey"); $success = $privKey->LoadAnyFormatFile('qa_data/pem/rsa_passwd.pem','passwd'); if ($success != 1) { print $privKey->LastErrorText . "\n"; exit; } // For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Rsa') $rsa = new COM("Chilkat.Rsa"); $rsa->ImportPrivateKeyObj($privKey); $originalData = 'This is the string to be hashed an RSA signed.'; // Indicate that we want the iso-8859-1 byte representation of the string to be signed $rsa->Charset = 'iso-8859-1'; // We want the RSA signature in base64 format $rsa->EncodingMode = 'base64'; $sigBase64 = $rsa->signStringENC($originalData,'sha256'); print $sigBase64 . "\n"; ?> |
