Description 

Author

This class can be used to encrypt and decrypt data with a given key.

It can take a string of data and encrypt it with a given key using pure PHP methods. The encrypted data can be compressed.

The class can also do the opposite, i.e. decompress and decrypt the previously encrypted data using the same key.

In Spanish:

Clase para php que usa un método propio, basico pero rápido:

Es un metodo simetrico por llave o contraseña, se puede usar un archivo como llave necesitando que el emisor/receptor tengan la misma llave.

Aenean aliquam vehicula nisi et tempor. Morbi commodo justo tincidunt tortor malesuada vitae laoreet augue vehicula.

Praesent dolor nibh, dictum ac volutpat et, pretium ac sapien."; // Encrypt with password phrase 'simpe_pass' $enc = $oCry->encode($lorem,'simple_pass'); // The $lorem is encripted and encode to base64 echo wordwrap($enc,60,"\n",true) ."\n\n"; // Decrypt encrypten content with the same password phrase $enc = $oCry->decode($enc,"clave"); // See the original lorem echo {$enc['data']}\n\n"; ``` Using a key file ---------------- You can use a random and binary byte data to encrypt a message, in linux you can do: ``` $ dd if=/dev/random of=keyfile.bin bs=1024 size=4 ``` This generate a 4KB binary file with random content ```php <?php $key = file_get_contents('keyfile.bin'); $oCry->encode($lorem, $key); ``` Use for passwords encryption? ----------------------------- No recomended, use an irrevertible hash algoritsm like md5, sha1, sha256, etc I wanna crack it! ----------------- You're welcome: - http://www.kriptopolis.org/node/7717 ``` Njg0NTU2NmE1OTM4YTVmZTEzZjYyOGU3MTFjOWNmYmUzNjE2ZTFhZThkMmZk NzQ4YWY0YmQyYzMwODkxZmQxNWqVm22nmZSuVlqtb6xybGpna8jKa5tUnnKb c5Vtp1lvbqWGa5NZbGXVaIdbZmydm6Geo1qek5hbc59pmciWZ1Vrl5aSZWmc ZMmXaZ2XlJpum5fGlZ5yk51jhrZjnZVnlMjHkWeUm5vIxWpim5qUk5icamhu k5ltlpvHZmxpxpaWvqpxgWSzoPZtEP7tiuVUKEzYZpLvJooRsn7iZrK2S6Tz vHI8ibObYh9bKHzaJDVbFfOJhTSeM+Z/uCXdRErmXAt9OYGaiVbcG2Kh8Xi2 wsOwkjxPMuVVzpoGJwjcEeygJUQgrLr730hmdpHO20FmHdVqnNWlkz1btK0o 4reOeuYRlFFGRmf1wGpspcLVnVfAszmaLBssdF5VxIkuaUq9sN12QDdWeSAN jk+Or8Fk23xadkzCqzoR3gjK85opFlsdpLns+KebedTgkzdTjsvTOixV42VY FnNYStIyU+8hWq+P51BJFCVnMbFi2+7JJ8rF9VZUXFFjbr1iAqX3FjOX6o+c bBMx3DkO ``` Vertion 2.0-1 (beta): - http://www.kriptopolis.org/node/9101 ``` YuvzadE6lxI1rsP3+VnhlzBicwXkBYN/Gyuuuxzndd6MDN4Xs81xWCB6PK3p hDzgit9cxMu0eOnpjSOPaIZ+5HnTiUtk32e0sX+7vVzmOvuh4I/IS/XsftC2 92CuerzcyNLYD8Rv0Fi4in7MUAu/W3kQxuR8DbUJQ+27S8BDR+Cjr3CHwqd5 X4uOhLGL1V7sszrNt0i1C7uliXpj04ZCFTvAqDwQltMjxa1io4W8hSfcFpOo cwkMDfAzl9icXBMShbrdy/UfWje+qhiTihTsLk9EhgJFvdwGNZ0Il+Bk+KfA 2fRAQmY2bDoCygx05j9i4vOoAZ31jvJAvpiR98uSohBMOiumiwIEI+9Ls6ht 5zpiJ+HetIuy0mBfEVIEREeKW4Hw2BgZ+Q4CciHagD9SJf4LlxK27MTXKHNm 1HI9TkCSCV5i4XTr5UI3+vGYJ8hJ5aOLOWTbo6cfujaPO4FYa4RiKVzxIPAE Ig9NmOtlsgHXoJiMFCPA8or7cOz4fJkW7+nQ0CMgx5X5 ```
