that wouldn't have worked.

Exactly what I was looking for.

RE: [PHP] crypt and decrypt a string

2001-10-05 Thread Nathan 

Here are some simple xor encoding functions that I wrote. This will keep
the average joe from peaking at your data.

function decode($data){
$data = base64_decode($data);
/* XOR data */
for($i = 0; $i < strlen($data); $i++){
$data[$i] = ~ $data[$i];
}
return $data;
}

function encode($data){
/* XOR data */
for($i = 0; $i < strlen($data); $i++){
$data[$i] = ~ $data[$i];
}
$data = base64_encode($data);
return $data;
}

Does anybody have an easy way to crypt and decrypt a string?  I see the
Mcrypt Encryption module but thats a little more gung-ho than I'm
looking for.  I'm not trying to encrypt sensitive data rather I'm more
trying obfuscate it a variable for a hidden tag.

Thought I remember seeing something using XOR?  Any ideas?

Thanks
Joel

[PHP] crypt and decrypt a string

2001-10-05 Thread Joel Ricker 

Does anybody have an easy way to crypt and decrypt a string?  I see the Mcrypt 
Encryption module but thats a little more gung-ho than I'm looking for.  I'm not 
trying to encrypt sensitive data rather I'm more trying obfuscate it a variable for a 
hidden tag.

Thought I remember seeing something using XOR?  Any ideas?

Thanks
Joel
