is there any other Base64 type encryption and decryption in php?

is there any other Base64 type encryption and decryption in php ?

The problem is that b开发者_Python百科ase 64 give a longer value and increases the size of the data whereas i'm looking for something to reduce the size of the data.

is there any ?

• base64 is not an encryption but an encoding
• pick an encryption algorithm from http://docs.php.net/mcrypt, see also http://docs.php.net/refs.crypto
• to (possibly) reduce the size use a data compression algorithm, see also http://docs.php.net/refs.compression

Base64 isn't so much encrypting and encoding - anyone can return a base64 encoded file/string into the original.

If you want to reduce the data size, try compressing it using for instance http://php.net/zip. If you still need to send the the data to another system, you could then base64 encode the resulting compressed data.

Do you actually want to encrypt the content (a security measure) or just make it viable for transmission inside for instance an XML or JSON stream, or is compression your only concern?
