(PHP ActiveX) Working with PEM Encrypted Private KeysDemonstrates how to load and save PEM encrypted private keys.
<?php // Starting in v9.5.0.49, all Chilkat classes can be unlocked at once at the beginning of a program // by calling UnlockBundle. It requires a Bundle unlock code. // For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Global') $chilkatGlob = new COM("Chilkat.Global"); $success = $chilkatGlob->UnlockBundle('Anything for 30-day trial.'); if ($success != 1) { print $chilkatGlob->LastErrorText . "\n"; exit; } // For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Pem') $pem = new COM("Chilkat.Pem"); $pemPassword = 'secret'; // To load a PEM file containing encrypted private keys, simply // provide the password. $success = $pem->LoadPemFile('/Users/chilkat/testData/pem/pemContainingEncryptedPrivateKeys.pem',$pemPassword); if ($success != 1) { print $pem->LastErrorText . "\n"; exit; } // For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.FileAccess') $fac = new COM("Chilkat.FileAccess"); $pemText = $fac->readEntireTextFile('/Users/chilkat/testData/pem/pemContainingEncryptedPrivateKeys.pem',$pemPassword); // To load a PEM from a string, call LoadPem instead of LoadPemFile: $success = $pem->LoadPem($pemText); if ($success != 1) { print $pem->LastErrorText . "\n"; exit; } // A few notes: // The PEM may contain both private keys and certificates (or anything else). // The password is utilized for whatever content in the PEM is encrypted. // It is OK to have both encrypted and non-encrypted content within a given PEM. // PEM private keys can be encrypted in different formats. The LoadPem and LoadPemFile // methods automatically handle the different formats. // One format is PKCS8 and is indicated by this delimiter within the PEM: // -----BEGIN ENCRYPTED PRIVATE KEY----- // MIICoTAbBgkqhkiG9w0BBQMwDgQIfdD0zv24lgkCAggABIICgE0PdHJmRbNs6cBX // ... // Another format, we'll call "passphrase" looks like this in the PEM: // -----BEGIN RSA PRIVATE KEY----- // Proc-Type: 4,ENCRYPTED // DEK-Info: DES-EDE3-CBC,A4215544D11C5D0C // // paqy9XRexcSjurHfG0xhCaUD0HrvIdhuC0CbRxxxeMlkLaV6+uT80rBxt2AaibWG // ... // Show the bit length of each private key: $numPrivateKeys = $pem->NumPrivateKeys; if ($numPrivateKeys == 0) { print (('Error: Expected the PEM to contain private keys.')) . "\n"; exit; } for ($i = 1; $i <= $numPrivateKeys; $i++) { // privKey is a Chilkat.PrivateKey $privKey = $pem->GetPrivateKey($i - 1); print $i . ': ' . $privKey->BitLength . ' bits' . "\n"; } ?> |
