(PHP Extension) SFTP Authenticate SecureDemonstrates how to do SFTP password authentication with secure strings. This example requires Chilkat v9.5.0.71 or greater.
<?php include("chilkat.php"); // Use "chilkat_9_5_0.php" for versions of Chilkat < 10.0.0 // This example requires the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. // Imagine we've previously saved our encrypted login and password within a JSON config file // that contains this: // { // "ssh_login": "2+qylFfC56Ck7OQQt/U2/w==", // "ssh_password": "5neIq9Jmn0E3p71N6Yc8TA==" // } $json = new CkJsonObject(); $json->LoadFile('qa_data/passwords/ssh.json'); $crypt = new CkCrypt2(); // These are the encryption settings we previously used to encrypt the credentials within the JSON config file. $crypt->put_CryptAlgorithm('aes'); $crypt->put_CipherMode('cbc'); $crypt->put_KeyLength(128); $crypt->SetEncodedKey('000102030405060708090A0B0C0D0E0F','hex'); $crypt->SetEncodedIV('000102030405060708090A0B0C0D0E0F','hex'); $crypt->put_EncodingMode('base64'); $ssLogin = new CkSecureString(); $ssPassword = new CkSecureString(); // Decrypt to the secure string.
