| 22 | // 1. Include phpseclib using composer and include the autoloader |

| 24 | |||

||
| 26 | // and only a few algorithms: AES and RSA! Feel free to extend this library! |
||
| 27 | // The sign/verify and encrypt/decrypt functions should be binary compatible with |
||
| 28 | // the actual openssl functions. |
